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.

    ANTHER CULTURE STUDIES IN RICE (Oryza sativa L.)
    (University of Agricultural Sciences GKVK, Bangalore, 41124) DALPAT, LAL; ASHOK, T H
    Rice (Oryza sativa L., 2n=24), a member of the family Poaceae is the most important cereal food crop in the world and feeds over half of the global population. Anther culture is useful technique in rice breeding programs, as production of haploid plants speeds up the breeding cycle by fixing homozygosity in one generation. The investigation was conducted to standardize culture media for callus induction and regeneration from anther derived callus of Azucena (O. sativa subsp. japonica) and Budda (O. sativa subsp. indica) rice varieties. Anthers from the panicle, with a distance of 11cm and 8 cm length between the subtending leaf and the flag leaf in Azucena and Budda respectively, were selected for the study. At this length, anthers contained uninucleate pollen grains. Before inoculation of the anthers, a cold pretreatment of 50C for 8 days was given to the selected panicles. Callus induction frequency in different media combination ranged from 0.66% to 6.66% was observed in N6 medium supplemented with 1.0 mg l-1 2, 4-D, 2.0 mg l-1 NAA and 0.5 mg l-1 Kinetin. In Azucena variety, highest callus induction (6.66%) while no callusing was found in Budda variety. Highest shoot regeneration (0.33%) from callus was observed in MS medium supplemented with 0.5 mg l-1 BAP, 0.5 mg l-1 Kinetin and 80 mg l-1 adenine sulphate. But all the regenerated shoots were albinos. Root formation was observed in MS medium without any growth regulator.
