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.

    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.
