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.

    STABILITY AND BREEDING POTENTIAL OF NEW CMS LINES, ADVANCED BREEDING LINES AND THEIR HYBRID COMBINATIONS FOR FLORAL AND PRODUCTIVITY PER SE TRAITS IN RICE (Oryza sativa L.)
    (University of Agricultural Sciences, Bangalore, 2022-09-14) ALLAM, CHINNAPA REDDY; Nagaraja, T.E
    Hybrid rice is one of the practically feasible and readily adoptable technologies to increase the production and productivity of rice. The present investigation was undertaken to elicit the information on new CMS lines and restorers, out-crossing performance of CMS lines evaluated for floral traits and estimation of variability, combining ability, heterosis and stability of hybrids for yield and yield components. Validation of candidate gene specific markers for major fertility restorer genes, Rf4 and Rf3 was carried out on twenty male parents. Using eight CMS lines and twenty testers in LxT design one hundred and sixty hybrids were produced. All the testers exhibited complete restoration. The analysis of variance for combining ability revealed significant differences among the genotypes tested for all the traits. The lines 2A, 3A, 4A and 7A and the testers R3, R4, R8, R10, R11, R12, R13, R15, R17, R18 and R19 were found good general combiners as they exhibited high (H) overall gca status. Among the hybrids, the crosses 2A/R18, 3A/R13, 2A/R8, 1A/R12 and 5A/R4 were the best specific combiners. Predominance of SCA variance indicated the presence of non-additive gene action in the inheritance of the traits studied. The hybrids 5A/R19, 7A/R19, 8A/R17, 4A/R11, 3A/R8, 7A/R3, 5A/R4, 6A/R17, 3A/R15 and 3A/R13 were chosen for multi-location testing as they exhibited significantly higher standard heterosis over the check KRH 4 for seed yield. The hybrids 6A/R17, 4A/R11, 5A/R19 and 7A/R19 exhibited stable performance across all the three locations (Mandya, Davanagere and Raichur) evaluated. These hybrids maybe tested over large number of environments for further confirmation before being exploited commercially.
