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.

    GENETICS OF LEAF CURL VIRUS RESISTANCE AND FRUIT YIELD IN INTER-SPECIES CROSS OF CHILLI (Capsicum spp.)
    (University of Agricultural Sciences, Bangalore, 2020-11-07) A. R., RAVIKIRAN; MOHAN RAO, A.
    Chilli leaf curl virus (ChiLCV) disease is one of the most devastating biotic constraints of chilli production in India. Development and deployment of cultivars resistant to ChiLCV disease is considered as eco-friendly and cost-effective method of mitigating production losses. Knowledge on number and mode of action of genes controlling resistance to ChiLCV disease and productivity per se traits is a pre-requisite to breed cultivars with improved productivity per se traits and resistance. Inter-species F1 derived between Byadagi Kaddi (P1) and Bhooth Jalokia (P2), parents, F2, F3 and BC1F1 plants were screened for responses to ChiLCV infection by artificial screening method at Main Research Station (MRS), Hebbal, UAS, Bangalore during Rabi 2018. All F1 plants were susceptible suggesting resistance to ChiLCV disease is recessive. A good fit of F2 and F3 population segregation to 15 susceptible: 1 resistant ratio and BC1F1 segregation to 3 susceptible: 1 resistant ratio suggests the involvement of two recessive loci in imparting resistance to ChiLCV disease. Genetics of fruit yield and its component traits was unravelled using six generation mean analysis. Both main genetic effects and duplicate digenic-epistatic effects were found to be involved in expression of productivity per se traits. These results are discussed in relation to selection strategy to breed chilli for enhanced productivity per se traits with resistance to ChiLCV disease.
