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 STUDIES AND VALIDATION OF TRANSPORTER SPECIFIC MARKERS FOR ZINC FORTIFICATION IN HYBRIDS OF RICE (Oryza sativa L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-10-07) ASHLESHA C, PATIL; Shashidhar, H. E
    Biofortification is a genetic approach and one of the most cost effective apporaches to alleviate micronutrient malnutrition. Compared to varieties hybrids offer an added advantage of biofortification as for mineral heterosis be explored. Seven hybrids, sixty one rice genotypes and three hundred F2 progenies of Gopal Doddiga x BI 33 were grown in University of Agricultural Sciences, GKVK, Bengaluru: The objectives of study were to estimate grain Zn content and productivity, design Zn transporters specific primers and validation of markers associated for grain Zn content. Significant genotypic differences were observed for all the quantitative traits in hybrids, F2 population and rice genotypes, indicating considerable amount of variation exists in these genetic materials. All hybrids manifested significant positive standard heterosis for most of the traits except for days to first flowering, plant height and panicle length. All hybrids except KRH 2 showed significant positive standard heterosis for grain Zn content. Only two hybrids exhibited significant positive standard heterosis for leaf and root Zn content. To understand variations in Zn content at sequence level, twenty primers were designed for eight genes. Amplified primer products of five primers viz. OsZIP2-l, OsZIP3-2, OsZIP4-3, OsZIP5-3, OsZIP6-1 were sequenced. Amplicon of primers exhibited nucleotide variation and manifested significant association with grain, leaf and root Zn content except OsZIP5-3. Four candidate gene primers found associated with grain Zn content in F2 population and only two primers manifested significant positive association with grain Zn content in rice genotypes. Highest Zn content and productivity was manifested for segregant (GB 224) from F2 population
