University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    GENETIC ANALYSIS FOR FRUIT YIELD AND YIELD COMPONENTS AND TAGGING TRAITS RELATED TO WATER USE EFFICIENCY IN TOMATO (Solanum spp.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2018-12-07) SURESH, K; SAVITHRAMMA, D. L.
    The present investigation was carried out to assess the variability and diversity for traits to water use efficiency and fruit yield in tomato germplasm during 2013 at GKVK, UAS, Bengaluru. The study revealed moderate to high PCV and GCV in most of the traits studied. K-mean cluster analysis revealed high level of morphological diversity as indicated by diverse clusters which is informative for breeding programs. Drought tolerance analysis identified MP, GMP, HAM and STI as more effective indices and EC 677068, EC 608271, EC 676792, EC 586980 and EC 676783 as most drought tolerant accessions. Further, twelve inter-specific hybrids developed from seven parents selected on basis of SCMR, SLA and Δ 13C were evaluated in RCB design during Kharif 2014. The parents EC 771612 and LA 2567 and crosses VRCT 174 × EC 519100, EC 771597 × EC 771612 × LA 2657 recorded significant gca and sca effects for most of traits related to WUE and fruit yield respectively. Moderate to high coefficient of variability was noticed in F2 and F3 populations of cross EC S. lycopersicum cv. EC 771612 × S. pennellii cv. LA 2567 and positive platykurtic skewed distribution indicating dominance based complementary gene interaction in the inheritance of traits studied. Five generations of the cross EC 661257 × LA 2657 revealed additive gene effect (d) and presence of duplicate dominant epistasis in all the traits except specific leaf area. Out of 212 SSRs surveyed for polymorphism only 24 were found to be polymorphic between the parents and were used in Bulk segregant analysis. SSR 19 and SSR 218 showed putatively linkage to SCMR and SLA respectively, can be used for selection of high water use efficient genotypes.
