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.

    Studies on combining ability, molecular diversity and response to late blight (Phytophthora infestans (Mont.) de Bary) in tomato (Solanum lycopersicum L.) under polyhouse condition
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Panchbhaiya, Ankit; Singh, Dinesh Kumar
    The present investigation was carried out at Vegetable Research Center of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, with the objectives to assess the genetic variability, molecular diversity, heterosis, combining ability, gene action, screening for late blight disease and estimation of percentage fruits damage due to Tuta absoluta in tomato. The analysis of variance for RBD and combining ability revealed significant genetic differences among 36 tomato genotypes for the fifteen yield related and ten quality traits under study. The magnitudes of PCV estimates were higher than the corresponding GCV estimates for all the characters. Moderate to high GCV together with moderate to high heritability and genetic advance as per cent of mean was reported for majority of the characters under study except characters related to earliness viz., days to 50 per cent flowering, day to first fruit set and days to fruit ripening. A total of 20 SSR markers tested out of which 16 were polymorphic and 4 markers had shown monomorphic on agarose gel. Among eight genotypes of tomato total number of 46 bands exhibited by these 16 SSR primers and among them 43 was polymorphic and 3 were monomorphic. The range of amplified products was 100-700bp approximately and number of alleles per locus varied from two to six. Average number of bands per primer was 2.86. A range of polymorphism was observed from 50 per cent to 100 per cent with an average of 93.23 per cent. The PIC value ranged from 0.117 to 0.891 with an average 0.596. Jaccard’s similarity coefficient varied from 0.52 to 0.94 with an average value of 0.70. PBT-9 and PBT-13 (0.94) were found to be the most similar genotypes among the eight genotypes studied followed by PBT-10 and PBT-13 (0.90). Minimum Jaccard’s similarity coefficient was found in PCT-1 with PBT-2 and PBT-5 (0.52). The clustering pattern obtained by SSR primer showed that PCT-1 (cherry tomato line) and PBT-4 (potato leaf type) showed deviation from existing cluster. Hybrids, PCT-1 x PBT-5, PBT-9 x PBT-5, PBT-9 x PBT-2 and PBT-2 x PBT-13 were found promising for earliness while, for fruit yield, PCT-1 x PBT-5, PBT-2 x PBT-13, PBT-9 x PBT-4 and PBT-5 x PBT-4 were found promising hybrids. For most of the fruit quality traits promising hybrids were PCT PCT-1 x PPT-2, PBT-9 x PBT-2, PBT-2 x PBT-4 and PPT-2 x PBT-10, hence these crosses could be utilized as commercial hybrids for earliness, high yielding and industrial processing, respectively. PCT-1 was identified as a best general combiner for maximum number of yield related and fruit quality traits followed by PPT-2 and PBT-5. The best specific combiner were PBT-2 x PBT- 13 followed by PBT-13 x PBT-10, PBT-9 x PBT-5, PCT-1 x PBT-5 and PBT-9 x PBT-4 for most of the yield related and fruit quality traits studied. Among all yield related and fruit quality traits most of the characters were under the control of non additive gene action with over or partial dominance effect except fruit firmness, hence these characters are suitable for hybrid breeding. For late blight disease resistant reaction, out of all F1 hybrids six cross combinations showed resistant and thirteen hybrids showed moderately resistance reaction. Among 28 hybrids, minimum average percentage fruits damage due to Tuta absoluta was found in PCT-1, PCT-1 x PBT-5 and PCT-1 x PBT-13.

    Genetic divergence and path coefficient analysis for yield and it’s related traits in French bean (Phaseolus vulgaris L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-06) Panchbhaiya, Ankit; Singh, Dhirendra Kumar
    The present investigation was carried out at Vegetable Research Center, G.B. Pant University of Agriculture and Technology, Pantnagar, Udham Singh Nagar (U.K.) during Jan – May, 2014. Seventy-four genotypes of french bean were grown in Randomized Block Design with three replications to assess variability, heritability, genetic advance, correlation coefficient, path coefficient, principal component analysis and D2 analysis. Observations were recorded on 22 quantitative characters viz., days to 1st flowering, days to 50% flowering, days to 50% pod setting, days to 50% maturity, days to 1st picking, days to 2nd picking, , number of pods per cluster, number of pod clusters per plant, number of pods per plant, pod dia, pod length, leaf length, leaf width, single pod weight, plant height, number of seeds per pod, seed length, seed width, 100 seed weight, seed yield per plant, pod yield per plant and pod yield per hectare. Analysis of variance revealed significant differences among all the genotypes for all the characters. On the basis of yield contributing characters the following genotypes were found superior viz., FB-202, followed by FB-209, FB-236, Arka Suvidha and FB-205. High heritability coupled with greater genetic advance was observed for plant height. Pod yield per plant showed positive and highly significant correlation with days to 50% flowering, seed yield per plant, plant height, number of pods per plant and weight of single pod. Path coefficient analysis revealed that single pod weight exerted high order of positive direct effect towards pod yield followed by number of pods per plant and number of pods per cluster. However, days to 2 picking, followed by 100 seed weight and days to 50% maturity, exerted negative direct effect towards pod yield. Principal component analysis showed that the first principal component had maximum of 30.85% variation of total variation, while the first seven principal component axes together with explained 83.41% variation, suggesting first seven principal axes are adequate to explain the variation in reduced dimension. Clustering through D2 analysis revealed maximum inter-cluster distance of clusters V and IX followed by cluster III and IX therefore, it is recommended that genotypes grouped under cluster IX, V and III were found promising for most of the traits including fruit yield, can be utilized as potent lines in french bean future breeding programme for the development of superior varieties.
