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 MAPPING AND LOCALIZATION OF STABLE QTLs FOR CHARCOAL ROT RESISTANCE IN SORGHUM {Sorghum bicolor{L,) Moench)
    (University of Agricultural Sciences GKVK, Banglore, 2007-08-30) PALAMREDDY S. REDDY; B. FAKRUDIN
    The genetic architecture of charcoal rot resistance and drought tolerance through the construction of molecular linkage maps and identification of QTLs can expectedly hasten the development of charcoal rot and drought tolerant sorghum cultivars. A set of 93 Recombinant Inbred Lines (RlLs) derived from 1822380 and E36-1 were evaluated for charcoal rot incidence and its related traits in sick plot at Main Agricultural Research Station, Dharwad and Regional Agricultural Research Station, Bijapur during rabi 2004. The RlLs displayed highly significant differences in their mean performance for all traits. A total of 240 RAPD, 262 genomic SSR and 20 genie SSR markers were used and of which 19 RAPD, 62 genomic SSRs and 4 genie SSR markers were found to be polymorphic between parents. All 85 markers genotyped across RlLs and a genetic linkage map was constructed by using MAPMAKER/EXP b 3.0 in which 80 markers were assigned to A, B, C, D, E, F, G, H, 1 and J linkage groups. A total genomic length of 650.3 cM was covered in this map. QTL analysis by composite interval mapping using QTL Cartographer (v2.5) indicated five and four QTLs for charcoal rot component traits at Dharwad and Bijapur locations respectively on A, B, D and 1 linkage groups. Three QTLs, one each for length of infection [xtxp297 on B), number of internodes crossed by the fungus (AC13 on A) and per cent lodging (xtxp343) explaining a phenotypic variance of 9.29, 12.54 and 15.2 per cent respectively were detected consistently between two locations and are considered to be the stable across environments.
