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.

    STUDIES ON GENETIC DIVERSITY IN OKRA (Abelmoschus esculentus (L.) Moench)
    (University of Agricultural Sciences, Bangalore, 2010-07-12) PRAKASH, KERURE; KITCHAIMUTHU, M.
    Okra is a popular green vegetable crop grown in India for its delicious tender pods. The extent o f initial genetic variability or genetic diversity determines the level o f crop improvement to large extent. Hence, the investigation on genetic variance was carried out with 44 okra genotypes. The high GCV and PCV were observed for plant height, inter-nodal length, first flowering node, first fruit producing node, average fruit weight and number o f seeds per fruit. High heritability coupled with high GAM were observed for all the characters sUidied, except for days to 50% flowering and days to 80% maturity showed high heritability with low GAM. In genetic divergence study, 44 okra genotypes had differed significantly for the 12 quantitative morphological characters and grouped into 12 clusters based on D2 analysis. The cluster III was the largest with eight genotypes followed by cluster I and VIII with seven, cluster II with five, cluster XII with three genotypes while, clusters IV, V, VI, IX, X and XI were included two genotypes each. Maximum inter-cluster distance was observed between the cluster VI and VIII (35.57) and intra-cluster distance was in cluster XII (28.14). The characters namely days to 50% flowering (35.62%), 100 seed weight (28.44%), number o f seeds per fruit (17.23%) and average fruit weight (8.14%) were directly contributed towards maximum divergence. The extent o f genetic diversity at molecular level was estimated for 44 okra genotypes using DNA marker (RAPD). Total genomic DNA was extracted and subjected to RAPD analysis using 14 arbitrary decamer primers, produced good polymorphic bands across the genotypes. RAPD data were subjected to calculate a SED matrix using Ward’s method. It clearly showed two major groups, first consisting o f three genotypes and second one further grouped into 11 subgroups included 41 genotypes. The present study also clearly grouped the six wild okra species in one cluster and five cultivated species in another cluster from the total o f eleven okra types, these results were holds good with by using ITS markers.
