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 GENETICS OF STERILITY MOSAIC DISEASE (SMD) RESISTANCE IN PIGEONPEA (Cajanus cajan (L.) Millsp.)

    The present investigation was carried to understand the genetics of resistance to SMD in pigeonpea. Genetic variability was studied among 70 pigeonpea genotypes for twelve leaf morpho-anatomical traits. Analysis of variance and descriptive statistics revealed presence of higher variability for these traits. The traits such as trichome numbers, length on both surfaces of leaf and leaf chlorophyll content showed highest GCV, PCV, broad sense heritability, genetic advance for direct selection. Screening of 70 genotypes against Bengaluru isolate of SMD revealed, only two cultivars (ICPL 7035 and BRG 3) and 11 wild genotypes were resistant. Correlations study on extreme 23 resistant and susceptible genotypes revealed significant negative association of trichome numbers on both leaf surfaces with other leaf traits. While, significant positive correlation was observed for trichome lengths on both surfaces of leaf with leaf thickness. The specific leaf area, weight, trichome numbers and length on lower surface of leaf showed higher discrimination function in relation to per cent disease incidence. Biochemical analysis revealed all susceptible genotypes with higher mean protein content (15.96) compared to resistant genotypes (9.06). SSAP and TRAP markers were developed based on active retroelement CcRT8 and two R genes. SSR markers revealed BRG 3 and ICP 7035 were the best resistant donors. The frequency distribution graph of F6 84RIL population against SMD revealed platykurtic (Kurtosis= -0.019) and negatively skewed (Skewness= -1.124) suggesting involvement of two or more genes for resistance. Parental polymorphism revealed, out of 55 SSR primers 40 were polymorphic between ICP 8863 (S) × BRG 3(R). Through bulk segregant and single-marker analysis three markers viz., AHSSR 50150, AHSSR 34130 and AHSSR 20125 were found closely associated with SMD resistance and explaining 21, 8 and 6 per cent of phenotypic variations. The information generated will be very useful for resistance breeding in pigeonpea.
