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.

    FRUITING HABIT GENETICS AND ITS INFLUENCE ON FRUIT TRAITS AND YIELD IN CHILLI (Capsicum annuum L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2018-12-17) ANILKUMAR, C.; MOHAN RAO, A.
    ruits node-1 and fruit orientation are economically important fruiting habit traits in chilli. Fruiting habit(s) could be solitary-erect (SE), solitary-pendant (SP), clustered-erect (CE) and clustered-pendant (CP). Farmer preferences for fruiting habit traits varies from region to region. An understanding of genetics of fruiting habit traits help accelerate breeding chilli cultivars with farmer-preferred desired combination of fruiting habit traits in high fruit yield background. Nine diverse genotypes contrasting for fruiting habit traits were crossed to develop fourteen F1 hybrids of seven distinct fruiting habit trait combinations, namely CE × SE, CP × SP, CE × CP, CE × SP, CP × SE, SE × SP and SE × SP during 2015 rainy season; The F2 and backcross generations (B1 and B2) were developed during 2016 summer. F1, F2, B1 and B2 of all the seven distinct types of crosses were evaluated and pattern of segregation for fruiting habit traits was recorded during 2016 and 2017 rainy seasons at the experimental plots of the Department of Genetics and Plant Breeding, University of Agricultural Sciences, Bengaluru. Results indicated bi-allelic monogenic inheritance of fruits node-1 and fruit orientation with solitary being dominant over clustered and pendant being dominant over erect orientation, respectively. Genes controlling fruits node-1 and orientation of fruits segregated independently. Magnitude and direction of additive genetic effects [a] and dominance genetic effects [d] and additive genetic variance (σ 2 A) and dominance genetic variance (σ 2 D) varied with the genetic background of the crosses and traits. Non-significant differences between fruiting habit classes such as (1) S & E, (2) S & P and (3) CE & CP for fruit yield and its contributing traits in both F2 and back cross populations and one pair of near isogenic lines (NILs) indicated the lack of influence of fruiting habit traits on fruit yield and its contributing traits.
