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.

    EVALUATION OF NEW INBRED LINES OF MAIZE (Zea mays L.) FOR TOLERANCE TO HEAT AND MOISTURE STRESS AND IDENTIFICATION OF POLYMORPHIC MARKERS BETWEEN CONTRASTING INBRED LINES
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-03) BUKKE KUTTI BAI; Ravikumar, R. L.
    Twenty one new inbred lines of maize derived through different cycles of pollen selection for heat stress tolerance were evaluated along with nine other inbred lines for seed yield and yield per se traits under field conditions during kharif 2018. Significant differences among inbred lines were observed among inbred lines for 14 quantitative traits except number of cobs per plant, cob diameter and number of kernels per row. High PCV and GCV were observed for plant height at 45 DAS, Anthesis Silking interval (ASI), number of kernels per row and seed yield per plant. High heritability coupled with high GAM was observed for plant height at harvest and seed yield per plant. Significant variability was observed among inbred lines for seedling heat and moisture stress tolerance in the laboratory testing. The inbred lines TPGB09 and TPGB03 were identified as heat stress tolerant while the inbred lines CPGB32 and TPGB12 were considered as moisture stress tolerant at seedling stage. Inbred lines developed through three cycles of pollen selection were more tolerant to heat stress at seedling stage compared to those developed through two and one cycle of pollen selection. Seven polymorphic SSRs markers each were identified between heats stress tolerant (BTM 2) and heat sensitive (CPGB30) and moisture stress tolerant (CPGB32) and moisture stress sensitive (BTM10) inbred lines. Expression of selected abiotic stress related genes viz., Hva22, Hsp, Sus1 and Sh1 was more in heat stress tolerant inbred line compared to heat stress sensitive inbred line under heat stress.
