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.

    MARKER ASSISTED SELECTION FOR ENHANCED ZINC CONTENT IN RICE
    (University of Agricultural Sciences, Bengaluru, 2018-08-20) NGUYEN PHUONG, THUY; SHASHIDHAR, H. E.
    A study was carried out using F3 and F4 progeny from a cross between ‘Gopaldoddiga’ and ‘ARB6’ cultivars. Analysis of variance for the traits evaluated showed highly significant differences (P < 0.001) among the genotypes for all traits. High estimates of GCV and PCV were observed for total number of tillers, number of productive tillers, biomass per plant, grain yield per plant and harvest index. GCV and PCV estimates were moderate for day to 50 % flowering, plant height, panicle length, 100 grains weight and brown grain Zn. PCV values were only slightly higher than GCV values under investigation for all traits. High estimates of broad sense heritability along with high GAM was observed for all the characters except GAM of plant height in F3 generation. Presence of positive relationship between grain yield and brown rice Zn concentration implies these traits can be used as a selection criterion from F4 generation onwards. To understand expression in Zn content at the sequence level, genes were identified as members of the ZIP family were chosen to design Zn transporter specific primers. Among twenty primers used three primers viz, OsZIP2-1, OsZIP3-2, OsZIP4-4 showed strong positive association with brown grain Zinc content. Brown rice Zn content and grain yield were high for hybrid progenies namely, GA 247-12-101, GA 247-12-141, GA 247-12-984, GA 240-450-35, GA 240-450-58, GA 240-450-21, GA 287-621-48, GA 287-63-172, GA 287-63-245, GA 287- 63-25, GA 214-132-20, GA 214-132-51, GA 214-132-136, GA 214-132-26 and GA 214- 132-279, and therefore can be recommended for planting under suitable aerobic conditions. These zinc enriched high yielding lines can be effectively utilized in rice biofortification programs across the globe.
