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 VARIABILITY FOR GAMMA RAYS INDUCED MUTAGENESIS FOR PRODUCTIVITY PER SE TRAITS AND MALE STERILITY IN ADVANCE GENERATIONS OF RAGI (Eleusine coracana L. Gaertn.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-07-22) PRASHANT VASISTH; RANGAIAH, S.
    important traits. Therefore, an investigation was aimed to study the gamma rays induced mutagenesis for male sterility and productivity traits in ragi. M3 seeds suspected for partial male sterility of two irradiated genotypes, GPU 28 with 3 doses (300,400,500 Gy) and KMR 204 with 2 doses (300,400 Gy) were used in present study. Screening for pollen sterility was done using acetocarmine test in M3 generation and observations were recorded on ten quantitative traits (except for sterile plants). Seventy six partial sterile mutants were identified having above 70% pollen sterility, were forwarded for evaluation of progenies in two experiments. In experiment (a) Sixty three (31 from M3 –GPU 28 and 32 from M3 –KMR 204) were evaluated in progenies phenotypically and 43 progenies were non segregating (fertile), 20 were segregating for fertility in M4 of GPU 28 and KMR 204. In experiment (b) a total of 13 partial sterile mutants (6 from M3 –GPU 28 and 7 from M3 –KMR 204) were evaluated in M4 and found 9 mutants with both male and female sterility. Fifty eight mutants (31 from M3 –GPU 28 and 27 from M3 –KMR 204) were advanced from M3 to M4 for the evaluation for yield. Ten M4 families (5 from M4 – GPU 28 and 5 from M4 –KMR 204) and 20 individual mutants (11 from M4 –GPU 28 and 9 from M4 –KMR 204) were found in M4 generation having higher seed yield than checks.
