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.

    DEVELOPMENT OF MYMV RESISTANCE IN GREENGRAM [Vigna radiata (L.) Wilczek] USING BULK SEGREGANT ANALYSIS
    (2023-01-20) POOJITHA; K. M. HARINIKUMAR
    Greengram (Vigna radiata (L). Wilczek) is an important pulse crop owing to its short growth duration, low water requirement, and its suitability for crop rotation and nutritional security being a rich source of protein. Greengram’s yield is greatly affected by numerous abiotic and biotic factors. Biotic stress produced by viruses especially Mungbean Yellow Mosaic Virus (MYMV) is the main constraint in mungbean production causing substantial yield reduction up to 85 per cent. In present study, 96 F2 genotypes from the cross between GG-ABL-449 x GG-ABL-265 were subjected to natural screening to assess their resistance or susceptibility against MYMV. F2 mapping population segregated in 70 susceptible: 26 resistant genotypes i.e., 3:1 ratio showing that resistance to MYMV is governed by monogenic recessive gene. Among 96 genotypes, seven were resistant, nineteen were moderately resistant, forty-one were moderately susceptible, twenty-two were susceptible and seven were highly susceptible. All the 96 genotypes were phenotypically evaluated for seven quantitative traits under field conditions. The GCV and PCV were found higher for important yield contributing traits and seed yield is positively correlated with major yield contributing traits. The parental polymorphism study showed two markers, CYR1 and VMYR1 polymorphic out of four Resistance Gene Analogue (RGA) primers linked to MYMV resistance which showed segregation in Bulk Segregant Analysis (BSA). The markers CYR1 and VMYR1 showed differences between bulks and parents with a fragment size of 445 bp and 1236 bp respectively in resistant bulks indicating that these markers are tightly linked to the MYMV resistance gene.
