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.

    Genetics of yield and quality characters in basmati rice (Oryza sativa L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-06) Anil Kumar; Mani, S.C.
    Rice (Oryza sativa L.), the second most important crop after wheat, is staple food for nearly 60 per cent of world population and contributes over 20 per cent of total calorie intake of human population. More than 90 per cent of rice is grown in the developing countries of Asia, where the problem of food supplies are acute. Globally, it is cultivated in about 146 million hectares, which produce 520 million tonnes of rough rice annually. In India, rice is grown in an area of 44.0 million hectares with a production of about 91.05 million tonnes and a productivity of 3.1 tonnes per hectare. Genetic improvement in rice has contributed significantly to food security in Asia during the last three decades, but to meet the growing demand of ever-increasing population, it is necessary to produce new rice varieties combining higher yield potential with excellent quality. The present investigation was conducted during Kharif, 2004 to Kharif, 2006 at the Crop Research Centre of G.B.P.U.A.T., Pantnagar. The main objectives of this study were (1) To apply simple and joint scaling tests for the detection of non-allelic interaction (2) To study the simple additive ±dominance and digenic models for the estimation of genetic components of variation (3) To study the gene action for grain yield, its components and certain quality traits in basmati rice (4) To estimate the extent of heterosis and inbreeding depression. Genetic analysis to grain yield ,its components and certain quality traits were based on 7 intraspecfic crosses (UPRI 2003-13 × Taraori Basmati, UPR 2879-98-105 × Pusa 1121-92-8-1-3-3, UPR 2879-98-105 × Type 3, UPRI 2003-18 × UPRI 93-104, UPRI 2003-19 × UPR 2879-98-105, UPR 2879-98-105 × Taraori Basmat, and UPRI 2003-13 × Type 3) involving 8 parents( UPRI 2003-13, Taraori Basmati, UPR 2879-98-105, Pusa 1121-92-8-1-3-3, Type-3, UPRI 2003-18, UPRI 93-104, UPRI 2003-19)and their F1¶s, F2¶s and backcross progenies. Six generations (P1, P 2, F 1¶s, F2¶s, BC1P1¶s and BC1P2¶s) of same 7 crosses, mentioned above, were evaluated by generation mean analysis in a Compact Family Block Design in three replications. Observations were recoded on days to 50% of flowering, plant height, number of effective tillers per plant, number of grains per panicle, panicle length, 1000-grain weight, grain yield per plant, kernel length, kernel breadth, kernel L/B ratio, cooked kernel length, cooked kernel breadth, cooked kernel L/B ratio, kernel elongation ratio, alkali digestion value, gel consistency and amylose content . Additive (d) component was found to be important for day to 50% flowering, plant height, number of grains per panicle, panicle length, 1000- grain weight, gel consistency and amylose content. Dominance gene effect (h) played an important role in governing the inheritance of days to 50% flowering, plant height, number of effective tillers per plant number of grains per panicle, panicle length, 1000- grain weight, grain yield per plant, kernel length, kernel L/B ratio, cooked kernel L/B ratio, kernel elongation ratio, alkali digestion value, gel consistency and amylose content. Both additive and dominance effects contributed significantly in the expression of day to 50% flowering, plant height number of grains per panicle, panicle length and 1000- grain weight. Among the digenic interactions, additive x additive (i) was found most important for days to 50% of flowering, plant height, number of effective tillers per plant number of grains per panicle, panicle length , grain yield per plant, kernel length and kernel L/B ratio, kernel elongation ratio, alkali digestion value, gel consistency and amylose content The dominance x dominance component (l) was relatively more important for days to 50% of flowering, plant height, number of effective tillers per plant number of grains per panicle, kernel length, kernel L/B ratio, cooked kernel length, cooked kernel breadth, kernel elongation ratio, alkali digestion value, and gel consistency , whereas additive x dominance (j) gene effect played important role in the expression of days to 50% of flowering, plant height, number of effective tillers per plant, number of grains per panicle, panicle length, 1000- grain weight, grain yield per plant, kernel elongation ratio, alkali digestion value, and gel consistency. Duplicate epistasis was observed in almost all the crosses for various quantitative and qualitative characters. Most of the crosses exhibited maximum heterosis for grain yield, 1000-grain weight; numbers of grains/panicle, panicle length, number of effective tillers/plant and plant height.

    Heterosis, combining ability, stability analysis and protein profiling in cowpea (Vigna unguiculata (L.) Walp.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-10) Pandey, Bhawna; Singh, Y.V.
    Present investigation was carried out during kharif, 2007, spring-summer 2007 and 2008 at the vegetable research center of GBPUA&T, Pantnagar. Eleven genotypes were evaluated for stability and out of these 11 genotypes 6 selected ones were crossed in diallel fashion. The experiment was laid out in randomized block design with three replications. During sprin-summer 2007 crosses were made and evaluated in kharif, 2007 and spring-summer 2008. The observations were recorded on 8 characters viz., plant height, days to 50% flowering, pods per plant, pod length, seeds per pods, seed yield per plant, 100 seed weight, insect incidence and virus incidence. The data was subjected to appropriate statistical analysis. Further, seed protein profiling of nine cowpea genotypes were done using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The pooled analysis of variance in stability analysis showed the significant difference among the genotypes for all the characters under study. For seed yield per plant IT-97K-1042, IT-98K-1111, IT-98K-452 and Pusa Komal were the most desirable genotypes showing their stability over a wide range of environments. Similarly, IT-82D-889 also showed higher yielding capacity but under high yielding environment. Two genotypes namely, Pusa Komal & Arka Garima exhibited greater stability for pods per plants and IT-82D-889, IT-97K-1042, Pusa Komal & Arka Garima were found stable for the character seeds per pods. Analysis of variance for combining ability revealed that GCA and SCA mean squares were highly significant for all the characters except virus incidence. For the parents, the GCA mean squares were larger in magnitude than SCA mean squares. The parents identified as promising were IT-98K-205 (plant height, days to 50 per cent flowering, pods per plant, insect incidence and virus incidence), IT-97K-1042 (pods per plants, number of seeds per pod, seed yield per plant, virus incidence and insect incidence). IT-93K-452 X Pusa Komal and IT-93K-452 X Swarn Harita were early flowering crosses as compared to their parents. The crosses found promising for pods per plants were IT-93K-452 X IT-98K-1111, IT-93K-452 X IT-98K-205 and IT-97K-1042 X IT-98K-1111; for pod length IT-98K-1111 X Pusa Komal , IT-98K-205 X Pusa Komal , IT-97K-1042 X IT-98K-205 and for seeds per pods IT-98K-1111 X Pusa Komal, IT-98K-205 X Pusa Komal , IT-93K-452 X Pusa Komal having high sca effect. For seed yield per plant IT-97K-1042 X IT-98K-1111, IT-98K-205 X Pusa Komal and IT-98K-205 X Swarn Harita were found best combinations. On the basis of standard heterosis, it can be concluded that heterosis breeding would be advantageous for the improvement of cowpea for yield and its quantitative traits. The crosses IT-97K-1042 X IT-98K-1111, IT-98K-205 X Pusa Komal and IT-97K-1042 X Pusa Komal were best heterotic crosses for seed yield as they demonstrated highly significant heterosis, over standard cultivar Pusa Komal. These crosses can be utilized for commercial exploitation of heterosis for getting maximum yield. Nine genotypes were distinguished into 7 groups on different banding pattern on 4 zones. The UPGMA analysis showed that there were two major groups consisted of I megagroup (IT-93K-452, IT-97K-1042, IT-98K-205, IT-98K-1111, IT-82D-889) and II megagroup consisted of Pusa Komal, Arka Garima, Local and Swarn Harita. The highest protein content was reported in IT-97K-1042 (30.46%) followed by IT-98-1111 (27.22%). These lines could be used in breeding programme for increasing protein content of local cultivars.

    Studies on inheritance of major quantitative and qualitative traits in soybean {Glycine max (L.) Merrill}
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-10) Singh, Rajneesh Kumar; Pushpendra
    The present investigation was carried out to know the nature and magnitude of gene effects governing the seed yield and its components along with correlation, heritability, genetic advance and certain qualitative traits at the G.B. Pant University of Agriculture and Technology, Pantnagar(India) during Kharif 2008-09. Four parental soybean genotypes three of which were released varieties viz., UPSM 534, PS 1347, JS 335, along with a wild spp. G. soja, were used to develop three crosses viz., PS 1347 x G. soja, PS 1347 x JS 335 and JS 335 x UPSM 534. Five generations namely, P1, P2, F1, F2 and F3 of each of these three crosses in a Compact Family Block Design with three replications were evaluated for the study of various genetic parameters. Observations on nine major quantitative characters viz., days to 50 % flowering, days to full maturity, plant height, number of pods per plant, seed yield per plant, dry matter weight per plant, harvest index, oil and protein content. Five qualitative traits viz. growth habit, leaf shape, flower color, pubescence color and yellow mosaic virus incidence were also studied for finding goodness of fit to the Mendelian segregation ratio. Highly significant/significant mean squares values for most of the characters suggested inherent genotypic differences in the experimental material for different quantitative traits. The broad sense heritability estimates were higher for dry matter weight per plant. However, number of pods per plant, dry matter weight per plant and plant height revealed high genetic advance. Thus breeding program should be planned to increase seed yield having low heritability and have good associations between certain agronomical characters and seed yield. Knowledge of relationship among yield and the other agronomic traits is of great importance in plant breeding, especially for the selection of genotypes for higher seed yield. Correlation studies showed that seed yield had significant positive correlation with plant height, number of pods per plant, dry matter weight and harvest index. The estimates of scaling test and five genetic parameters revealed predominance of both additive as well as non additive gene action for most of the characters. Both types of epistasis were also found in the present study. Presence of duplicate type of epitasis in almost all the crosses for various quantitative characters indicated complex nature of inheritance. Therefore, in this situation simple selection is likely to be useful for effective utilization of both types of additive and nonadditive gene effects simultaneously. The inheritance of qualitative traits revealed that growth habit, leaf shape, flower color, pubescence color segregated in 3:1 ratio and governed by monogenic inheritance whereas, inheritance of yellow mosaic virus resistance was found to follow 15:1 pattern and governed by two recessive genes in JS 335 x UPSM 534 cross. Based on the observations derived from the present investigation, it is therefore suggested that more emphasis should be given for the improvement of yield components viz., dry matter weight per plant, number of pod per plant, harvest index in soybean crop.

    Elucidating the genetics and physiology of seed longevity in soybean {Glycine max (L.) Merrill
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-09) Bhardwaj, Pushpak Mani; Pushpendra
    The present investigation was carried out at Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India. Using soybean as experimental material with objectives; to screen out different soybean genotypes for seed longevity; to study the genetics of seed longevity; to evaluate the selected genotypes (parents and crosses) for the level of ABA content and to study the ABA response for expression of LEA proteins level and seed germination. Three soybean genotypes viz., AGS 334, Bhatt and T-49, were selected to investigate the genetics of seed longevity. The significant differences were reported for seed longevity at different time periods of seed storage for both methanol stress and standard germination test at room temperature. The genotypic and phenotypic coefficients of variation for standard germination test was high after eight months of seed storage followed by six months of seed storage, while for methanol stress, the genotypic and phenotypic coefficients of variation was high after two months of seed storage fallowed by at after four months of seed storage. ABA content was highest in T-49 (10.04) and lowest in AGS 334 (1.01). The progenies which had T-49 in its pedigree showed that ABA content was half of the ABA content of T-49. High heritability estimates were reported for ABA content, plant height, germination percentage and 100 seed weight. High genetic advance was recorded for plant height followed by germination per cent, ABA content and 100 seed weight. ABA content reported to have significant and positive genotypic and phenotypic correlation with plant height. Four out of six crosses except for AGS 334 x Bhatt and Bhatt x AGS 334 exhibited highly significant positive standard heterosis for ABA content with Bhatt used as check parent. Highly significant combining ability variances due to GCA, SCA and reciprocals for plant height, germination, ABA content and 100 seed weight indicated presence of additive, non-additive and maternal gene effects for these traits. Segregation pattern of crosses AGS 334 x Bhatt; AGS 334 x T-49; and their reciprocals in F2 and F3 generation revealed the presence of one dominant gene whereas, cross Bhatt x T-49 and its reciprocal crosses revealed the presence of two dominant genes responsible for seed germinability. SDS-PAGE analysis of nine genotypes using NTSYS-pc v 2.1., separated the genotypes into two main cluster I and II at 0.794 similarity coefficient, comprising of four and five genotypes, respectively. SDS-PAGE analysis revealed the presence of good amount of LEA like proteins in the genotype T-49 and in the progenies involving it as one of the parents in the cross.
