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.

    Studies on seed longevity with packaging materials, genetic variability and molecular diversity of soybean (Glycine max (L.) Merrill)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-08) Bhakuni, Vandana; Shukla, P.S.
    The present study was taken up to study seed longevity of soybean seeds stored in different packaging materials, effect of priming on seed quality parameters, analysis of genetic variability and molecular marker diversity analysis using sixteen different SSR primers for effective selection and improvement of crop plant. For field experiment 12 varieties were planted in randomized complete block design with three replications during Kharif 2013 and 2014 at N. E. Borlaug Crop Research Centre. All the lab experiments were conducted in the seed testing laboratory at Breeder Seed Production Centre and department of Genetics and Plant Breeding, G. B. Pant University of Agriculture and Technology, Pantnagar. The analysis of variance for different field characters indicated highly significant differences among varieties for all the ten characters studied in both the years. This indicated that the experimental material contained sufficient amount of variability. In both the years estimated values of phenotypic coefficient of variation were higher than genotypic coefficient of variation for all the characters studied. Plant height exhibited highest phenotypic coefficient of variation followed by yield per plant in both the years. Most of the traits included in this investigation were considered highly heritable as they have shown to be associated with moderate to high estimate of broad sense heritability. In 2013 as well as 2014 highest heritability in broad sense was obtained for plant height i.e., 97 and 98% respectively. The expected genetic advance in 2013 varied between 0.26% for number of seeds per pod to 35.61% for plant height. Similarly, in 2014 expected genetic advance varied from 0.09% (number of seeds per pod) to 37.44% (plant height). High heritability coupled with high genetic advance was observed for plant height and number of pods per plant in both the years. Analysis of variance revealed that storage periods, packaging materials and the variety to be stored had a significant effect on all the thirteen seed quality parameters studied in both the years. During both the years it was observed that there was a decrease in germination per cent and vigour with time. Highest values for germination and vigour were observed at P1 (after 45 days of storage) while it decreased at P3 (after 135 days of storage). The present study revealed that after 135 days of storage varieties like PS 1024, PK 327, Bhatt and Bragg had germination per cent below 70% while all the remaining varieties, Ankur, PS 1225, PK 472, PS 1092, Kalitur, JS 335, PS 1347 and PK 1029 maintained their germination upto 70%. With respect to containers, it is apparent from the results that tin container maintained seed quality the most; followed by jute bag, paper bag and cotton bag. Seeds stored in earthen pot lost their vigour and quality the most. All the varieties exhibited decrease in oil per cent with time while the effect of packaging material was not significant on oil per cent. Mean value for oil content reduced from 15.72 (after 60 days of storage) to 12.99% (after 120 days of storage). It was observed that packaging material, priming agents and varieties to be treated had a significant effect on seed quality parameters. Highest germination was recorded in seeds primed with CaCl2.2H2O (62.51), followed by GA3 (61.83) and nSiO2 (57.18%) while unprimed seeds had the lowest germination per cent (44.12%). Highest germination per cent was recorded for seeds stored in jute bag when primed with GA3 (70.75) which was at par with the seeds stored in tin container primed with CaCl2.2H2O (69.44%). The assessing of SSR diversity of twenty soybean genotypes revealed that the Jaccard’s similarity coefficient estimates between pair of different varieties varied from 0.59 [between Kalitur and JS 335, Ankur and Bhatt] to 0.92 [between PK 472 and Ankur]. The average number of alleles per primer was 4.125, while percentage of all bands that showed polymorphism was 100%. The UPGMA ordered the population of twelve varieties into two main groups namely Group A and Group B and five clusters. Based on dendrogram PS 1347 and Ankur were found to be most distant.

    Heterosis and gene effect studies for seed yield and related traits in Indian-mustard (Brassica juncea L. Czern & Coss)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-07) Pathak, Sanjana; Pant, Usha
    Indian mustard (Brassica juncea (L.) Czern and Coss) is a largely self-pollinating major oilseed crop with upto 15 % out crossing under natural field conditions. Due to its wide cultivation it is essential to identify high yielding genotypes and formulate effective breeding programmes on the basis of genetic parameters. Devising a suitable improvement programme for desired improvement would depend on the knowledge of gene effects operating in the breeding population. Therefore, the present investigation was under taken to (1) test the adequacy of different models, (2) detect additive, dominance and epistatic gene effects (3) generate information about the genetics of heterosis in different crosses. The present investigation was carried out during rabi 2013-14, 2014-15 and 2015-16 in Indian mustard (Brassica juncea L.) comprising four families viz; PR-2009-6 × Albeli (Family A), PR-2009-6 × RGN-73 (Family B), PR-2009-6 × NDYR-8 (Family C) and KMR-13-3 × PR-20 (Family D). The study was based on six generations of these crosses which were sown in Compact Family Block design with 3 replications. The data were subjected to generation mean analysis following joint scaling test (Cavalli, 1952) for obtaining the necessary information. Analysis of variance showed presence of significant variability among families and also within families (among progenies) for various traits under study except for days to maturity, seeds per siliquae and siliquae length. Fixable effects [d] and [i] were found important in the inheritance of plant height, seed yield per plant and glucosinolate content. Among non fixable effects, dominance [h] gene action was significantly important for determining length of main raceme, number of siliquae on main raceme, siliquae length, oil content, seed yield per plant and glucosinolate content. Interaction gene effects were found significant in controlling plant height, length of main raceme, number of secondary branches per plant, siliquae on main raceme, siliqua length,1000seed weight, oil content, seed yield per plant and glucosinolate content. Thus both main effects and epistatic effects were found important in controlling the various traits under study. Family A showed considerable interaction effects for siliquae on main raceme, number of seeds per siliquae and oil content. Family B displayed epistatic interactions for characters such as plant height, length of main raceme, siliquae on main raceme, siliquae length, oil content seed yield per plant and glucosinolate content. Both main and interaction effects were found significant in Family C for characters namely, plant height, siliquae on main raceme, seed yield per plant and glucosinolate content. Family D had significant interaction effects important for the improvement of characters such as plant height seed yield per plant and glucosinolate content. The estimates of genetic parameters under adequate model were employed to calculate the value of expected heterosis. Close agreement between observed and expected heterosis implies that non-allelic interaction is important for heterosis. The heterosis manifested in different crosses studied was of high magnitude, significant in all the four families for seed yield per plant and number of primary branches per plant. For secondary branches pre plant significant positive heterosis was realized in Family B and D. The estimate of observed heterosis for seed yield per plant ranged from 15.67% in Family D to 11.97% in Family A. For primary branches per plant observed heterosis was highest for Family A and lowest in Family B. Observed heterosis for secondary branches per plant was significantly high for Family B and D. Considering the overall results, it is apparent that most of the characters in all the four families were found under the control of both fixable (additive, additive x additive) and non fixable (dominance and epistatic) gene effects coupled with duplicate type of epistasis. In such situations hybridization system such as multiple or reciprocal recurrent crossing which exploit both additive and non additive gene action simultaneously are important for genetic crop improvement. The duplicate epistatsis was found to be associated most of the traits which slows down the progress of breeding programme and hinders the isolation of desired type in the early segregating generations therefore, selection must be practiced in the advanced generations

    Study of genetic variability character association and path analysis in Jatropha curcas L.
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-08) Joshi, Lalit; Bandyopadhyay, B.B.
    Efficient utilization of energy determines the development and prosperity of economic growth of a country. Mostly solar energy, nuclear energy and chemical energy are used by developing and developed countries. Chemical energy is used in the form of petroleum fossil fuel. Limited availability and resource crunch of petroleum fossil fuel oil appears as major constraints in the process of economic development among these countries and draws special attention of the scientists for developing an alternative source of petroleum oil. The seeds of Jatropha curcas plant are used as an alternative source of biofuel productions. An experiment was carried out during 2014-2015 with seven years old healthy, disease and insect free plants of sixteen Jatropha genotypes from a set of germplasm collections collected from different regions of India. The original seeds of germplasms were planted on 27-29 July, 2008 in Randomized Block Design with three replications at Medicinal Plant Research and Development Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, India. Schedule agronomic practices were carried out to obtain good plant stand. Data were recorded during 2014-15 on five randomly selected plants from each plots of each genotype separately. Field observations were recorded on twelve characters viz., plant height (m), collar diameter (cm), number of primary branches per plant, number of secondary branches per plant, days to flowering (after 31st July), post floral period (days), number of fruit clusters per plant, number of fruits per cluster, fresh weight of hundred fruits (kg), dry weight of hundred fruits (kg), 100 seed weight (g) and seed yield per plant (kg). The analysis of variance revealed that highly significant differences among all the sixteen genotypes for all characters. The study on genetic parameters showed high genetic variance, genetypic coefficient of variation, heritability, genetic advance and genetic gain over percent of mean for days to flowering, secondary branches per plant, seed yield per plant and fruit clusters per plant suggesting the presence of additive genetic control for these traits. The number of primary branches per plant, number of fruit cluster per plant were significantly positively correlated with seed yield per plant, while 100 -seed weight established negative and significant correlation with seed yield per plant both at genotypic and phenotypic level. Path analysis at phenotypic and genotypic level revealed that number of fruit cluster per plant emerged as a major direct and indirect contributor for seed yield. Residual effect indicated that the involvement of these twelve characters could explain 73 and 77 % variability respectively at phenotypic and genotypic level. Four Jatropha genotypes viz., Pant JCP-2, Pant JCP-1, CRJ-29 and LBJJ-23 were identified as promising and could be utilized for genetic improvements in breeding of Jatropha population for biofuel production

    Studies on association of yield and quality characters in advanced promising clones of sugarcane (Saccharum species complex.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-07) Rajeshwar Ram; Jeena, A.S.
    The present investigation was carried out in randomized block design, with 30 advanced clones/varieties of sugarcane including four checks viz., CoPant 05224, CoPant 97222, CoS 8436 and CoS 767 planted as plant and ratoon crop during the year 2014-15 and 2015-16 at Norman E. Borlaug Crop Research Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Distt. U. S. Nagar, Uttarakhand. Genetic variability and character association was studied for different yield and quality parameters like number of tillers, number of millable canes, cane weight, juice brix, sucrose %, purity %, CCS % percent, cane yield and CCS yield in plant crop as well as in ratoon crop. The statistical analysis was carried out to estimate character mean, coefficients of variation, heritability, genetic advance, correlation coefficients and path coefficient for different yield and quality characters. Analysis of variance revealed highly significant differences among all the clones for all yield and quality characters under study. Study of coefficient of variation in plant and ratoon crops revealed relatively high contribution of genotypic variance in determining phenotypic variation for most of the characters except for juice purity. Highest PCV was exhibited by commercial cane sugar yield (28.99%) followed by cane yield (28.92%) and lowest PCV (1.64%) was observed for juice purity in plant crop. In ratoon crop, highest PCV was exhibited by cane yield (32.04%) followed by commercial cane sugar yield (31.3%) and lowest PCV (1.82%) was observed for juice purity. The high value of heritability and genetic advance in plant crop for the characters viz., number of tillers, number of millable canes, single cane weight, cane yield and commercial cane sugar yield and in ratoon crop, characters viz. number of tillers, cane height, single cane weight, average number of nodes, inter-nodal length, cane yield and commercial cane sugar yield indicated additive gene effects and suggesting that direct selection of these traits would be effective for improvement of clones. The correlation coefficient study at genotypic and phenotypic level revealed highly significant positive correlation of the characters number of tillers per plant, number of millable canes, single cane weight and commercial cane sugar yield with cane yield in both plant crop as well as ratoon crop. This shows that the improvement of these characters will result in improvement of cane yield. Path analysis revealed that the characters number of tillers, number of millable canes, single cane weight and commercial cane sugar yield have direct positive effect on cane yield at phenotypic level in the plant as well as ratoon crop while the characters number of millable canes, single cane weight, sucrose percent, juice purity percent and commercial cane sugar yield have direct positive effect on cane yield at genotypic level in the plant as well as ratoon crop. These characters could be used as selection indices for yield improvement in sugarcane.

    Studies on genetic parameters for quantitative and qualitative traits in soybean [Glycine max (L.) Merrill]
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-07) Bharath, Kunduru; Singh, Kamendra
    The present investigation was carried out at N. E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India, during kharif, 2014 with 165 genotypes (160 entries and 5 checks) of soybean for eight qualitative and fifteen quantitative characters to assess genetic divergence, genetic variability, inter-character correlation and their direct and indirect effects, screening of genotypes against YMV, BP and RAB and protein profiling of selected genotypes using SDS-PAGE to evaluate the diversity in protein content. Results showed that qualitative characters played an important role in crop diversity and the characters flower colour and hilum colour contributed maximum towards genetic diversity. Analysis of variance showed significant differences among the genotypes for all the characters under study, which indicated adequate genetic variability among the experimental material. Based on Hierarchical cluster analysis, the 165 genotypes were grouped into 10 clusters. The maximum numbers of genotypes (124) were grouped in Cluster VII and minimum (1) in Clusters I and VI. The maximum divergence was observed between Clusters II and III (91.59) followed by I and IX (79.32) and III and X (78.13), while the least divergence was observed between Clusters IV and V (33.06). Cluster IX was found to include the most desirable genotypes as it exhibited highest cluster mean values for majority of the characters under study. Based on inter-cluster distance, cluster mean values and per se performance, the potential parental combinations that could be considered for enhancing the overall yield levels in soybean were, PS 1225 x Jupiter, PS 1225 x JS 20-79, PS 1225 x Cat 209, PS 1225 x SL (E) 1, PS 1225 x AMS 100-16-4-1-3, Jupiter x JS 20-79, Jupiter x Cat 209, Jupiter x AMS 100-16-4-1-3, JS 20-79 x Cat 209, JS 20-79 x SL (E) 1, JS 20-79 x AMS 100-16-4-1-3, Cat 209 x SL (E) 1, Cat 209 x AMS 100-16-4-1-3, SL (E) 1 x AMS 100-16-4-1-3, while the crosses Jupiter x SL (E) 1 and Cat 209 x AMS 50B would be promising to recover superior segregants for oil and protein contents, respectively. In general, the magnitudes of PCV were higher than those of GCV and ECV for all the characters with a close correspondence between the values of PCV and GCV for majority of the characters under study. This indicated a minimum role of environment in their expression and hence, selection based on phenotype could be rewarding for such characters. Highest and lowest values of PCV, GCV and Genetic advance as % of mean was observed for seed yield per plant and protein content, respectively. High estimates of heritability and genetic advance were reported for plant height, number of nodes per plant, number of pod bearing nodes per plant, number of pods per plant, 100-seed weight, dry matter weight per plant, harvest index, seed yield efficiency, oil content and seed yield per plant which indicated a role of additive gene effects in their expression. Correlation studies showed that seed yield exhibited significant positive correlations with majority of the characters like plant height, number of primary branches per plant, number of nodes per plant, number of pod bearing nodes per plant, number of pods per plant, number of seeds per pod, 100-seed weight, dry matter weight per plant, harvest index, seed yield efficiency and oil content. However, a significant but negative correlation was recorded between oil and protein contents. Path analysis indicated that, dry matter weight per plant, seed yield efficiency, number of pods per plant, 100-seed weight, number of seed per pod and number of primary branches per plant exhibited positive direct effect in influencing seed yield. Screening of genotypes against YMV, BP and RAB showed that only two genotypes i.e., PS 1225 and PS 1480 were highly resistant against these three diseases. Also, 31 genotypes showed high resistance to YMV and BP, however, the rest all were found to be susceptible to one or the other of these three concerned diseases. Based on the estimates of protein content, 11 significantly divergent genotypes were selected from three arbitrary groups containing high, medium and low protein contents to study the diversity in total seed protein using SDS-PAGE. Although, significant differences in protein content were observed among the 11 selected genotypes, results obtained from their protein profiling through SDS-PAGE revealed only qualitative differences with a few bands absent in certain genotypes, but no quantitative differences in terms of protein content were observed. On the basis of genetic diversity analysis, the genotypes PS 1225, AMS 100-16-4-1-3, JS 20-79, Jupiter, Cat 209, SL (E) 1 and AMS 50B were identified as superior donors for yield contributing traits, whereas the studies on genetic variability, correlation and path coefficient analysis showed that the number of primary branches per plant, number of nodes per plant, number of pods per plant, number of seeds per pod, 100-seed weight, dry matter weight per plant, seed yield efficiency and oil content were the most important yield attributes to be emphasized during selection programs for increasing the overall yield levels in soybean.
