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.

    Estimation of genetic diversity based on morphological and molecular markers in lentil (Lens culinaris Medikus)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2014-08) Kuldeep Kumar; Panwar, R.K.
    Lentil (Lens culinaris Medikus) is one of the versatile food legumes with diversified uses as food, fodder and fuel. The present investigation on 206 lentil genotypes was carried out in Rabi 2012-2013 to study the extent of variability, heritability and genetic advance, extent of association between yield and its components, to ascertain direct and indirect effects of component characters on seed yield, to study genetic diversity through Mahalanobis D2 Statistics based on twelve characters and assessing molecular diversity through ISSR marker. In general, phenotypic coefficients of variation (PCV %) were greater than genotypic coefficients of variation (GCV %) and in same direction. Highest PCV % and GCV % were found for number of primary branches per plant followed by number of secondary branches per plant, economic yield per plant (gm), harvest index (HI), number of pods per plant, number of seeds per pod. Number of pods per plant, harvest index (HI), Economic yield per plant (gm) showed high values of broad sense heritability and the expected genetic advance was observed highest for harvest index and number of primary branches. Correlation studies showed that indicated that economic yield showed positive and highly significant at genotypic and phenotypic correlation level with number of primary branches per plant and number of pods per plant. Path coefficient analysis based on phenotypic correlation coefficient revealed that harvest index had highest positive direct effect on economic yield followed by biological yield, number of secondary branches per plant and plant height. Biological yield exhibited high positive indirect effect on economic yield followed by number of primary branches per plant followed by days to maturity, pods per cluster, number of secondary branches per plant,100 seed weight and plant height. On the basis of Mahalanobis D2 Statistics fifteen clusters were formed. The Cluster I comprised of seventeen genotypes, Cluster II and XV comprised ten genotypes, Cluster III and XI had twelve genotypes, Cluster IV and XIII had fifteen genotypes, V and XIV consisted of eighteen genotypes, Cluster VI had twenty two genotypes, Cluster VII had nine genotypes, Cluster VIII had nineteen genotypes, Cluster IX had five genotypes, Cluster X had sixteen genotypes, Cluster XII had eight genotypes. The relative divergence of each cluster from other cluster (inter-cluster distance) indicated high degree of divergence between cluster IV and XIII, followed by cluster IV and XIV. Number of pods per plant contributed maximum towards genetic divergence followed by number of secondary branches per plant, biological yield, number of primary branches per plant, number of seeds per pod, 100-seed weight, harvest index and economic yield. In the present study 14 ISSR primers were taken, out of them five primers gave amplification. These primers gave a total of 28 loci, all primers are polymorphic. A dendrogram generated by cluster analysis derived from ISSR markers divided 24 lentil genotypes into two group A and B. Major group A have 22 genotypes and major group B have 2 genotypes. EC78511 and EC267528-B were most similar and EC223191 and EC78511 were most distant. This Indicates ISSR as a useful tool in determining the genetic diversity among genotypes in lentil because it is not influenced by environmental conditions.
