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 FODDER YIELD AND ITS CONTRIBUTING TRAITS IN FODDER COWPEA (Vigna unguiculata L. Walp.)

    There is an essential need to develop high yielding varieties in fodder crops to meet out the current increasing demand for green fodder. So useful information on genetics of fodder yield and its contributing traits helps in enhancing pace and efficiency of breeding programmes for developing high yielding varieties. Genetics of fodder yield and its contributing traits was unraveled using simplified triple test (STTC) and combining ability cross analysis during 2018-2019, at the experimental plots of Zonal Agricultural Research Station (ZARS), University of Agricultural Sciences, Bengaluru. STTC analysis revealed the important role of epistasis in the inheritance of fodder yield and its contributing traits. The estimates of additive and dominant genetic variance were biased due to epistasis but magnitude and direction of bias varied with traits. The results suggests not to ignore epistasis in the studies designed for determining the relative magnitude of additive and dominant genetic variances controlling the target traits. Combining ability analysis revealed predominance of dominant gene action in the inheritance of all the traits except for days to plant height, leaves plant-1 and green fodder yield plant-1 for which additive gene action was predominant. The lines MFC-09-1 and EC-394839 (for productivity per se traits) and testers KBC-5 and IC-402101 (for productivity per se traits) identified as good general combiners, could be used as parents in the development of high biomass yielding varieties.
