Govind Ballabh Pant University of Agriculture and Technology, Pantnagar
After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960.
The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

ThesisItem Open Access GENETIC DIVERSITY AND CHARACTER ASSOCIATION FOR YIELD AND ITS ATTRIBUTING TRAITS IN BITTER GOURD (Momordica charantia L.)(G. B. Pant University of Agriculture & Technology, Pantnagar-263145, 2023-07) Shalvi; Maurya, S. K.In the present research, forty genotypes including two check varieties Pusa Vishesh and Pant Karela-1 were evaluated in randomized complete block design during spring-summer, 2023 at the Vegetable Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, to study the sixteen growth and yield related characters. The analysis of variance of the data revealed extremely significant treatment values for all of the characters. The magnitudes of GCV and PCV were found to be higher for number of primary branches per vine, number of internodes per vine, main vine length (m), stem diameter (mm), average fruit length (cm), number of node to first male flower, number of fruits per vine, average fruit diameter (mm), average fruit yield per vine (kg), fruit yield per ha (q) and average fruit weight (g). High heritability together with high genetic advance was reported for the characters, number of internodes per vine, average fruit weight (g), average fruit yield per vine (kg), average fruit diameter (mm) and fruit yield per ha (q), suggesting that these characters had additive-additive gene action and were suitable for direct phenotypic selection. Average fruit yield per vine (kg) revealed a significant positive association with variables such as main vine length (m), average fruit weight (g), average fruit length (cm), average fruit diameter (mm), and fruit yield per hectare (q), indicating the importance of these traits in selection for yield. The inter cluster D2 values of the six clusters revealed that highest inter cluster generalized distance was observed between cluster III and VI, followed by cluster II and cluster III indicating that the genotypes in these clusters can be used as parents in hybridization programme to develop high heterotic hybrids. Relative contributions of the characters to the overall divergence showed that among all the characters, average fruit diameter contributed maximum. The Principle Component Analysis (PCA) depicted that the first five components contributed to 80.02 % of the total variance. The bi-plot of PC-I and PC-II revealed significant heterogeneity, displaying a dispersion pattern of demarcated genotypes. The scatter plot created by PCA highlights the varied genotypes located further away from the place of origin and hybridization between these various genotypes may be used as a parent. Among the 40 genotypes under study, four genotypes namely PBIG-7/23 (259.26), PBIG-18/21 (229.95), PBIG-6/21 (187.16) and PBIG-9/21 (172.22) were found superior against standard check Pant Karela 1 (147.88) for fruit yield per ha (q) and they may be utilized as a commercial cultivar after following standard release procedure as well as future bitter gourd breeding programme.ThesisItem Open Access Genetic divergence in potato (Solanum tuberosum l.)(G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-01) Singh, Pappu; Maurya, S.K.The current study was carried out at Vegetable Research Center of G.B. Pant University of Agriculture and Technology, Pantnagar during rabi season of 2020-21. Twenty- six genotypes including two check namely Kufri Pukhraj and Kufri Chipsona-4 and evaluated in Randomized Block Design using three replications at spacing of 60 cm × 20 cm. Observations were recorded for 15 horticultural traits including emergence percent at 30 DAP, plant height at 40 DAP, number of shoots per plant, number of leaves per shoot, girth of shoot, number of internodes per stem at 80 DAP, number of tubers per plant, average tuber weight, tuber weight per plant, tuber yield, tuber dry matter content, specific gravity of tuber, total soluble solid, ascorbic acid content and protein content. Statical analysis of data was done using the standard programmes for genetic variability in general performance, PCV and GCV, heritability, genetic advance as percent of mean, correlation coefficient, path coefficient analysis and D2 analysis, analysis of variance revealed significant difference for most of the characters. A narrow range of genetic differences between the PCV and GCV indicates that the traits are mostly governed by genetic factors with minimum environmental influence on the phenotypic expression of these traits. High heritability coupled with high genetic advance as percent of mean were found for tuber yield (97.13), average tuber weight (96.21), total soluble solid (93.50), protein content (92.72), number of leaves per shoot (92.29), ascorbic acid content (90.56), tuber weigh per plant (83.56), number of internodes per stem at 80 DAP (80.06) and number of shoots per plant (70.75) suggested that there is high scope for improvement in these characters through direct selection. Tuber weight per plant, number of tubers per plant, number of leaves per shoot, number of shoots per plant, average tuber weight, plant height at 40 DAP, specific gravity of tuber, number of internodes per shoot at 80 DAP, girth of shoot and emergence percent at 30 DAP were highly significant and positively correlated with the tuber yield. The phenotypic path coefficient showed a direct positive effect by traits like number of leaves per shoot, average tuber weight, plant height at 40 DAP, specific gravity of tuber, tuber weight per plant, tuber dry matter content, number of tubers per plant, emergence percent at 30 DAP on tuber yield, whereas number of internodes per stem at 80 DAP, girth of shoot, protein content, ascorbic acid content, number of shoots per plant, total soluble solid on tuber yield. All the twenty- six genotypes of potato were classified into clusters on the basis of D2 analysis and maximum inter-cluster distance were found between cluster X and VIII (21.73) This indicate that inter genotypic crosses between the members of cluster X and VIII would exhibit high heterosis and is also likely to produce new recombinants with desired traits. Highest cluster mean value for tuber weight per plant (439.83) and for average tuber weight (82.73) were presented in cluster V and X respectively. Among the twenty-six genotypes, six genotypes namely Kufri Pukhraj, Kufri Ganga, P-57, Kufri Lalit, Kufri Surya and Atlantic were found most promising for most of the characters. Thus, with this study it may be concluded that above information about genetic divergence can be utilized in potato future breeding programme for the development of high yielding and commercial cultivar.ThesisItem Open Access Study on heterosis breeding, combining ability and gene action in bitter gourd (Momordica charantia L.)(G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Nawani, Amit; Maurya, S.K.The present investigation entitled “Study on heterosis breeding, combining ability and gene action in bitter gourd (Momordica charantia L.)” was carried out at the experimental field of Vegetable Research Centre of G.B.P.U.A.&T., Pantnagar during summer season of 2022. The six diverse monoecious bitter gourd genotypes viz., PBIG-3, PBIG-6, PBIG-8, PBIG-9, PBIG-10, PBIG-18, and PBIG-18 were selected and crossed during rabi season (2021-22) in diallel mating design (without reciprocal) to develop 15 F1 crosses. The F1s and parents were sown at a spacing of 150 cm × 75 cm in randomized complete block design with three replications. Observations were recorded on five randomly tagged plants in each entry for 16 quantitative traits of bitter gourd. The data were subjected to appropriate statistical analysis. The analysis of variance indicated significant difference among all the genotypes for all the characters. The combining ability analysis revealed that both gca and sca variance were significant for all the characters. Non-additive gene action played a major role in controlling the characters like days to anthesis of first male and female flower, node number to first male and female flower, primary branch per plant, internodal length (cm), main vine diameter (m), days to first harvest, average fruit yield per plant (kg) and fruit yield (q/ha). On the basis of gca effects, among parental lines, PBIG-18 showed highest gca effects for days to anthesis of first male and female flower, days to first harvest, internodal length, number of fruits per plant, average fruit yield per plant (kg) and fruit yield (q/ha). Among hybrids, PBIG-8 × PBIG-18 showed highest sca effects for days to anthesis of first male and female flower, days to first harvest and primary branch per plant, whereas, hybrid PBIG-6 × PBIG-18 showed ideal sca effects for fruit yield per plant (kg) and fruit yield (q/ha). The gene action, predictability ratio and average degree of dominance was observed 1.0, respectively for all the characters except average fruit length, indicating the predominance of non-additive (dominance and epistasis) gene action in the expression of different traits under study, hence heterosis breeding will be an effective tool for genetic improvement of these traits in bitter gourd. The two crosses namely PBIG-6 × PBIG-18, PBIG-9 × PBIG-10 were found best heterotic combinations along with best sca effects for most of the important economic traits and are worth exploiting on commercial scale. These crosses yielded 276.5 q/h, and 259.2 q/ha as compared to the 156.1 q/ha of the standard check i.e. Pant Karela-1.ThesisItem Open Access Genetic variability and interrelationship of yield and its contributing traits in okra [Abelmoschus esculentus (L.) Moench](G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-08) Beri, Sonakshi; Verma, AlkaThe present investigation on “Genetic Variability and Interrelationship of Yield and its Contributing Traits in Okra [Abelmoschus esculentus (L.) Moench]” was carried out during the Kharif season 2021 at Vegetable Research Centre, Govind Ballabh Pant University of Agriculture & Technology, Pantnagar, with the objectives to assess genetic variability, heritability and genetic advance, correlation coefficient, path coefficient and genetic divergence for different quantitave traits. Nineteen genotypes including check were evaluated in Randomized block design with three replications. Analysis of variance revealed that highly significant genetic differences were present among the genotypes of okra for ten characters studied. Moderate to wide range of mean values among the genotypes for different characters were observed. Moderate to high genotypic and phenotypic coefficient of variation were reported for majority of characters under study except days to 50% flowering and days to first harvest. High heritability coupled to high genetic advance were recorded in average pod weight, pod yield per plant, number of primary branches per plant, plant height and total fruit yield indicating direct selection for these traits will be effective. Highly significant and positive correlation of total pod yield was observed with pod yield per plant followed by number of pods per plant and average pod weight indicating the possibility of simultaneous selection for these traits. The higher magnitude of positive direct effect on total fruit yield was contributed through pod yield per plant followed by pod length and number of primary branches per plant. Therefore, direct selection of these traits will be gratifying. Genotype PO 405 which was early as well high yielder than the check and PO 414 also found good yielder as well immune to YVMV can be recommended for cultivation. Clustering through D2 analysis revealed maximum inter-cluster distance between cluster II and cluster VI, thus the genotypes grouped under cluster II and cluster VI may yield maximum heterosis upon hybridization and also create wide variability including transgressive segregants in selfed generation.ThesisItem Open Access Study of genetic diversity in Bitter gourd (Momordica charantia L.)(G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Dhathri, Mondeddula; Singh, D.K.Bitter gourd (Momordica charantia L., 2n=2x=22) is a tropical and subtropical vegetable of the family Cucurbitaceae, widely grown in Asia and Africa for its edible fruit. Twenty-eight genotypes including two check varieties Kashi Mayuri and Pant Karela-1 were evaluated in randomized block design during March-July, 2022 at the Vegetable Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, to study the nineteen growth and yield related characters namely., main vine length(m), number of primary branches per vine, internodal length(cm), number of nodes per vine, days to first male flower, days to first female flower, node number at which first male flower appears, node number at which first female flower appears, days to 50% flowering, sex ratio, days to first fruit harvest, fruit length (cm), fruit diameter (cm), fruit weight (g), number of fruits per plant, number of seeds per fruit, number of pickings, fruit yield per plant(kg), fruit yield per hectare(q). The pooled data was subjected to statistical analysis. The result of analysis of variance revealed that difference among bitter gourd genotypes was highly significant for all the characters. High PCV and GCV were recorded for main vine length(m), number of primary branches per vine, number of nodes per vine, node number at which first male flower appears, node number at which first female flower appears, sex ratio, fruit length (cm), fruit weight (g), number of fruits per plant, number of seeds per fruit, fruit yield per plant(kg), fruit yield per hectare(q). High heritability and high genetic advance as percentage of mean reported in the character number of fruits per plant followed by days to first female flower, fruit yield per hectare(q), fruit weight (g), number of nodes per vine, number of primary branches per vine, sex ratio, fruit yield per plant(kg), days to first fruit harvest, fruit length (cm), main vine length(m), days to 50% flowering, days to first male flower, number of seeds per fruit, node number at which first male flower appears, fruit diameter(cm), node number at which first female flower appears, number of pickings and internodal length(cm). Fruit yield per plant(kg) exhibited highly significant and positive association with fruit weight(g), fruit length(cm), fruit diameter(cm), number of pickings and number of seeds per fruit indicating the importance of these traits in selection for yield. The path coefficient analysis reported that highest positive direct effect on fruit yield per plant(kg) was contributed by the character fruit weight(g) followed by number of fruits per plant, days to first male flower, number of pickings, fruit diameter(cm) and days to first fruit harvest. The inter cluster D2 values of the eight clusters revealed that highest inter cluster generalized distance was observed between cluster VIII and VII indicating that the genotypes in these clusters can be used as parents in hybridization programme to develop high heterotic hybrids. Five genotypes namely Pusa Rasdar, Punjab karela-15, Pusa Vishesh, PBIG-36 and Kashi Mayuri were superior for fruit yield per plant(kg) and these genotypes may be considered as promising ones for the improvement of the bitter gourd cultivars in breeding programme.ThesisItem Open Access Assessment of genetic diversity using morphological traits in Brinjal (Solanum melongena L.) germplasm(G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Chandra, Kavya; Verma, AlkaThe present experiment entitled “Assessment of Genetic Diversity Using Morphological Characters of Brinjal (Solanum melongena L.) Germplasm” was conducted at Vegetable Research Centre of GBPUA&T, Pantnagar, Uttarakhand, during the kharif season of 2021-22. Seventy genotypes including two checks were evaluated in Augmented block design II. During the experiment observations of fifteen parameters were taken. The quantitative parameters which were recorded were days to 50% flowering, days to 1st harvest, fruit length, fruit diameter, number of fruits per plant, average fruit weight, fruit yield per plant, total fruit yield, plant height and number of primary branches. Analysis of variance revealed that all the characters under study showed highly significant differences except fruit diameter. High genotypic and phenotypic coefficient of variation were observed for fruit diameter, number of fruits per plant, average fruit weight, fruit yield per plant and total fruit yield. A narrow range of difference between PCV & GCV was seen which indicates a little influence of environment on phenotypic expression of these traits. High heritability along with high genetic advance as per cent mean was observed for all the characters studied indicating direct selection for these traits would prove useful. Fruit yield per hectare showed positive correlation with number of fruits per plant, average fruit weight, fruit yield per plant suggesting that selection for these traits would be effective for improving the yield in brinjal. Higher magnitude of positive direct effect on yield was observed in number of fruits per plant, average fruit weight, fruit yield per plant which indicates their true positive and significant association with yield. Hence, direct selection for these traits will be rewarding. Seventy genotypes were classified into four clusters following cluster analysis. Maximum inter-cluster distance was found between cluster I and III indicating that genotypes in these clusters can be used as parents in hybridization programme. Among the characters studied, fruit yield per plant showed maximum contribution towards total diversity followed by total fruit yield, number of fruit per plant, fruit diameter, number of primary branches, average fruit weight, fruit length and days to 50% flowering. Based on above observations, the genotypes PB-229, PB-262, PB-228, PB-261, PB-242 and PB-239 in long group, with PB-219 and PB-264 in round fruited group were found superior and can be recommended for cultivation under Tarai region of Uttarakhand.ThesisItem Open Access Genetic divergence studies on morphological and biochemical traits in tomato (Solanum lycopersicum L.)(G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-07) Subhashree, Subhasmita; Singh, DhirendraTomato (Solanum lycopersicum L.) is an autogamous diploid (2n = 2X = 24) vegetable belonging to nightshade family (Solanaceae). Tomato is believed to be originated from the mountainous regions of Andes in Peru, Ecuador and Bolivia regions of South America. The present investigation entitled “GENETIC DIVERGENCE STUDIES ON MORPHOLOGICAL AND BIOCHEMICAL TRAITS IN TOMATO (Solanum lycopersicum L.),” was carried out at the Vegetable Research Centre, G.B.P.U.A.&T., Pantnagar. The experiment was comprised of 34 genotypes, i.e., JTL-1908, BT-2-5-21, ATL 18-08, Kashi Aman, Punjab Ratta, RHTHY-01, VNR-17019, ARTH-3689, RCDTH-21, Improved Bhagya, VNR-17017, VNR- 13008, RCDTH-11, RCDTH -2, RCDTH-15, VNR-15067, Julie, VRTH-16-112, CRPVRTH-70, Arka Rakshak, 2019/ TODVAR-1, 2019/ TODVAR-2, 2019/ TODVAR-4, 2019/ TODVAR-5, 2019/ TODVAR-6, 2019/ TODVAR- 10, Kashi ToLCV Hybrid-2, Kashi ToLCV Hybrid-3, PUSA ToLCV Hyb-10, Arka Aditya along with four checks, i.e., Pant T3, Kashi Chayan, Punjab Chhuhara and Kashi Tomato Hybrid-2 were sown in Augmented-II design with five blocks during Rabi season, 2021 to study sixteen morphological and biochemical parameters, namely, days to first flowering, days to 50%flowering, days to first fruit set, days to first picking, plant height (cm), number of fruits per plant, average fruit weight (g), yield per plant (kg), number of locules, pericarp thickness, TSS ( 0 Brix), acidity, ascorbic acid (mg/ 100 g fruit weight), total carotenoids (mg/ 100 g fruit weight), lycopene content (mg/ 100 g fruit weight) and total phenol (mg/ 100 g fruit weight) content . Molecular characterization was carried out by using lycopene specific SSR molecular marker to check polymorphism in genetic level among the thirty four genotypes.The pooled data were subjected to statistical analysis for analysis of variance (ANOVA), estimation of genetic variability, heritability h2(b), genetic advance, correlation studies, path coefficient analysis and genetic divergence analysis (D2 statistics). The traits, such as, number of fruits per plant, average fruit weight (g), yield/plant (kg), pericarp thickness (mm), ascorbic acid content (mg/ 100 g fruit weight), lycopene content (mg/ 100 g fruit weight), and total phenol content (mg/ 100 g fruit weight), high phenotypic coefficient of variability (PCV) and genotypic coefficient of variability (GCV) along with higher heritability was reported. Average fruit weight and number of fruits /plant is found to be positively correlated with yield per plant and also has a high direct positive effect on yield. Yield per plant contributes the maximum percentage towards the genetic divergence of the current study. Polymorphic information content (PIC) value of all the primers was laid between 0.469 to 0.614, symbolizes medium range of polymorphism between the genotypes. The genotypes grouped under major cluster A and cluster B are more diverse in nature with having 60% of similarity which symbolizes maximum divergence clusters. Based on the results of the study, it was revealed that the genotypes varied widely, indicating that there was opportunity for selection-based improvement of the tomato genotypes. The yield will be significantly increased by selection based on characteristics such as, number of fruits per plant and average fruit weight. The genotypes 2019/TODVAR 5, CRPVRTH-70, Pant T3 (C), 2019TODVAR 4, and Arka Rakshak were highlighted as promising ones for the yield related attributes based on the mean performance of the genotypes studied for different traits. The processing traits of Arka Aditya, Punjab Chhuhara, and VNR- 17019 were confirmed to be superior.ThesisItem Open Access Response of potato (Solanum tuberosum L.) to zinc application(G.B.
