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.

    Morphological, physiological and molecular characterization for heat tolerance traits in bread wheat (Triticum aestivum L. em. Thell)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-06) Amarjeet Kumar; Swati
    Research work on combining ability analysis and gene action for yield and heat tolerance contributing traits along with characterization of wheat genotypes on the basis of morpho-physiological traits and linked SSR markers for heat tolerance of wheat genotypes was carried out using line x tester analysis. Randomized Block Design with three replications in two environments was used to study combining ability, gene action and heterosis, at Norman E. Borlaug Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar. 20 characters were used viz., days to 75% heading, days to maturity, plant height (cm), peduncle length (cm), tillers per plant, flag leaf area (cm2), spike length (cm), spikelets per spike, grains per spike, grain weight per spike(g), 1000 grain weight (g), biological yield per plant (g), grain yield per plant (g), harvest index (%), awn length, grain filling duration, heat susceptibility index, chlorophyll content, canopy temperature depression and relative injury (%). Field and molecular screening of genotypes was undertaken to classify the genotypes according to thermo tolerant and thermo sensitive response. JOB666 was identified as best general combiner for maximum number of traits spike length , number of productive tillers per plants, grain yield per plant, biological yield per plant, grain filling duration followed by HD3091 for heat susceptibility index, relative injury (%), chlorophyll content at 15 days after at anthesis, peduncle length, WAXWING for plant height, awn length, chlorophyll content at anthesis and HPW211 for number of grains per spike, grain weight per spike, spikelets per spike in timely sown condition(E1) whereas, in late sown (E2) HD2961was recognized as good general combiner for maximum number of traits viz., grains per spike, canopy temperature depression (CTD) at anthesis, tillers per plant, spikelets per spike followed by HD3091 for relative injury (%), harvest index, peduncle length, WH1124 for chlorophyll content at anthesis, grain yield per plant, 1000 grain weight and JOB666 for CTD and Chlorophyll content at 15 days after anthesis. However, JOB666 emerged as best general combiner for maximum number of traits in pooled condition viz spike length, tillers per plant , grain yield per plant, biological yield per plant, CTD, grain filling duration followed by HD3091 for peduncle length, harvest index, heat susceptibility index and WH1124 for 1000 grain weight, chlorophyll content at anthesis. Among the tester, WH1105 was best general combiner for chlorophyll content at 15 days after anthesis. WAXWING x HD3059 were identified as good specific combination for grains per spike, spikelets per spike, WAXWING x HD2967 for 1000 grain weight , grain yield per plant, HD3091 x WH1105 for relative injury (%), DBW90 x HD3059 for CTD at anthesis in E1. CBW12 x HD3059 was good specific combination for grains per spike, spikelets per spike and awn length, CTD at 15 days after anthesis, respectively. Whereas, UP2843xHD3059 for tillers per plant, DBW90 x HD3059 for grain yield per plant and HD2329 x WH1105 for relative injury (%) were good specific combination in E2. However, HD2961 x HD2967 for grain yield, UP2843 x WH1105 for grain filling duration, biological yield per plant, HD2329 x WH1105 for relative injury (%) were good specific combiner. In timely sown condition, JOB666 x HD3059, WAXWING x HD3059, WAXWING x HD2967, HPW211 x WH1105, JOB666 x HD3059, WH1021 x HD3059, WH1021 x WH1105, WAXWING x WH1105, CBW12 x HD2967, MACS6272 x WH1105, WH1124 x HD3059, JOB666 x HD3059, HPW211 x HD2967 and HD3091 x WH1105 were recognized as the best heterotic hybrids over all the levels, for the characters tillers per plant, spikelets per spike, 1000 grain weight, weight of grain per spike, grain yield per plant, biological yield per plant, harvest index, chlorophyll content at anthesis, CTD at anthesis, relative injury%, days to 75% heading, grain filling duration, grains per spike and heat susceptibility index, respectively. In late sown condition, HD2961 x HD2967, WH1124 x HD3059, HD2329 x HD3059, WH1124 x HD2967, HD2961 x HD3059, WH1124 x HD3059, JOB666 x HD3059, HD2961 x WH1105, JOB666 x WH1105, HD2329 x HD2967, WH1124 x HD3059, WAXWING x HD3059, HD2329 x WH1105 and HD3091 x WH1105 were recognized as the best heterotic hybrids over all the levels for the characters tillers per plant, 1000 grain weight, weight of grain per spike, grain yield per plant, biological yield per plant, chlorophyll content at anthesis, CTD at anthesis, Chlorophyll content at 15 days after anthesis, relative injury %, days to 75% heading, grain filling duration, flag leaf area and heat susceptibility index, respectively. Genotypes HD2329, DBW90, HD3091, JOB666, HD2329, DBW90, JOB666, WH1021 and JOB666 were selected as heat tolerant on the basis of morpho physiological basis. Three primers Xgwm 268, Xgwm 484 and Xcfd 43 showed polymorphic bands out of fourteen primers, which were further used for molecular analysis.
