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.

    Standardization of picking time and comparative study of seed quality parameters of parents, hybrids and F2 seeds of bell pepper (Capsicum annuum L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-07) Amit Kumar; Rajendra Prasad
    The present investigation was conducted during Kharif, 2004, at Hill Campus, Ranichauri with six parents and sixteen hybrids. The experiment was laid out in randomized block design with three replication. Characters were studied for genetic variability viz. Plant growth habit, shape of fruits, fruit colour at marketable maturity, days to first picking, plant height, fruit length, fruit diameter, fruit weight, number of fruits per plant, fruit yield per plant, seed yield per plant, TSS, ascorbic acid and chlorophyll content. Seed quality parameters viz. number of seed per fruit, weight of 100 seeds, germination per cent, seedling vigour index I and vigour index II under four pickings to compute comparison of different picking for seed quality and comparative study of parents, hybrids and F2 seeds for different seed quality parameter. Character associations between seed quality parameters were also computed for dependency of one character to on another. Data were analyzed statistically to work out for various traits and their comparative account were made. Significant differences in different characters were found for morphological and biochemical parameters. The days to first picking ranged from 53 days (HC X Pz ) to 81 days(SSP), Plant height 24.66 cm (Pg X Pz) to 49.66 cm (Pz X Pg), fruit length 4.01 cm (Oshrogion) to 6.39 cm (Osh X SSP), number of fruits per plant 9.50(HC X Pz) to 3.12 (SSP X HC).Chlorophyll „a‟ was found to be maximum in Osh X SSP (9.48) and minimum in Pg X SSP (2.5). Chlorophyll „b‟ ranged from 1.738 (Pg X SSP) to 5.98 (Pg X Yw). Comparative study of four picking showed maximum germination per cent in III picking, maximum 100 seed weight in III Picking. Seed vigour index I was maximum in second picking and highest vigour index II in fourth picking. Comparison for seed quality parameters for parents, hybrids and F2 showed the significant superiority of F1 over the F2 with respect of germination per cent but there was no significant differences recorded among parents hybrids and F2 for vigour index I and vigour index II. The character associations were also made for morphological parameter with seed quality yield and positive significant association fruit length, fruits diameter, flesh thickness, and number of fruits per plant with seed yield per plant. Similarly phenotypic correlation of seedling parameters was also made among germination per cent, shoot length, root length, fresh weight, Dry weight and vigour index I and vigour index II. Number of seedling character also showed positive association. From the present investigation it can be concluded that various morphological trait can be used to asses fruit and seed quality more precisely along with the biochemical parameters. Present study clearly showed that picking time is definitely going to affect the seed quantity and quality. Laboratory techniques also showed helpful method to judge the seed quality. Character association can be used as an alternative to estimate the seed quality and quantity. It is difficult to give general recommendation with respect to picking to all seed quality and quantity attributes but more précised study can be done with respect to genotype and case specific.

    Morphological and molecular diversity in sorghum (Sorghum bicolor (L.) Moench) genotypes in relation to grain mold
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-08) Amit Kumar; Vishunavat, Karuna
    The present investigation on “Morphological and molecular diversity in sorghum (Sorghum bicolor (L.) Moench) genotypes in relation to grain mold” was carried out Crop Research Centre and Seed Pathology Laboratory, Department of Plant Pathology, G.B. Pant University of Agriculture and Technology, Pantnagar, Uttrakahand, India, during the year 2005-07 with twenty six genotypes. The investigation was undertaken to study the screening of sorghum genotypes for grain mold, analysis of means and variance for plant and seeds parameter, biochemical and molecular characterization of sorghum cultivars in relation to grain mold and Inter-character correlation for plant, seeds and mold incidence. Twenty six sorghum genotypes were categorized into five groups for the mold infestation on the basis of visual assessment which revealed that three varieties viz. HC-136, MP Chari Red and GFS-4 were found to be highly resistant, which was further conformed by the blotter method. The analysis of variance revealed significant differences among the varieties for the quantitative characteristics. Higher estimates of phenotypic and genotypic variance were recorded for the characters viz. total height of the plant at maturity, natural height of the foliage up to base of flag leaf, time of panicle emergence and the length of panicle without peduncle. The PCV and GCV were of the same magnitudes for majority of the characters. However, relatively higher magnitude of difference between PCV and GCV was observed for three characters viz., anther length, visible length of panicle neck above the sheath and 1000 seed weight indicating the greater role of environment in their expression. The present experimental material possess high heritability coupled with high to low moderate genetic advance for majority of the characters except for the character anther length indicating substantial proportion of additive genetic variance in their expression thereby, confirming their consistency over the years. Among the seed quality parameters high significant correlation was observed between seed weight per 25 seeds with seed density and volume per 25 seeds. Weight per 25 seeds with vigour index I, germination percentage with vigour index I and vigour index II. Association studies between mold incidence and seed quality parameters revealed significant positive correlation between electrical conductivity with mold incidence. However, quality parameters viz., density per seed and percent germination showed negative but significant correlation with mold incidence. Out of a total of 14 quantitative plant parameters only one characters viz., anther length showed significant and positive correlation with mold incidence. Inter-correlation among fungal complex (Curvularia lunata, Fusarium moniliforme and Phoma sorghina) were mostly positive. Seed storage protein profiling and RAPD analysis revealed that clustering of the varieties could roughly be coincided with their mold infestation percentage at laboratory conditions.
