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.

    MOLECULAR ANALYSIS FOR GRAIN ZINC AND IRON CONTENT, ROOT MORPHOLOGICAL TRAITS AND WHOLE PLANT ARCHITECTURE IN RICE (Oryza sativa L.) ACCESSIONS UNDER AEROBIC CONDITION
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2019-06-27) BHARATH PRASAD, C. T.; SHASHIDHAR, H. E.
    The present study was aimed at apprehending the information regarding micronutrient acquisition by various genotypes of rice under aerobic condition. Fifty germplasm accessions which were highly contrasting in their characters for shoot, root and mineral (Zn and Fe) content were chosen and replicated in the field and innovative PVCpipe- root experiment was employed to study the rooting behavior during kharif-2015 and summer-2016 in aerobic condition. A significant variance among the accessions were observed for all the characters. Genetic parameters (GCV, PCV, h2, and GAM) showed significant higher difference for iron and zinc content in brown and polished grains in both the seasons. Among the genotypes, Azucena and AM-65 exhibited highest zinc, while Dodda mullare recorded the lowest. Gopal doddiga and Kuduve karanji recorded highest iron in both brown and polished rice whereas Kaduvalai recorded the lowest. Polishing of brown rice results in less percentage loss of zinc compared to iron. Molecular marker analysis was done using 87-candidate gene and SSR primers, only 7 candidate gene primers and 10 SSR primers were found to be polymorphic, while rest were monomorphic and generated unique alleles of various band size and are source of new alleles. Single-marker analysis exhibited statistically significant association with grain brown Zn (BZn), polished Zn (WZn), maximum root length (MRL), root number (RN), root dry weight (RDW) and root fresh weight (RFW). This proves that the markers were tightly linked to concerned traits. The study reveals that adequate diversity still exists in the cultivar genepool for steady varietal improvement.
