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.

    Mapping quantitative traits loci, and prediction and validation of genomic estimated breeding values for seed yield and its component traits in dolichos bean (Lablab purpureus L. Sweet)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2018-04-02) CHANDRAKANT; Ramesh, S.
    DNA marker-assisted identification and introgression of the key quantitative trait loci (QTL) into elite genetic background effectively complement phenotype-based selection and help enhance pace and efficiency of breeding crops, dolichos bean being no exception to this. The linkage map was constructed using genotypic data of 58 polymorphic SSR markers (after excluding 2 markers exhibiting significant segregation distortion and 31 markers which did not fit to the threshold recombination frequency of 0.3, on 109 F10 recombinant inbred lines (RIL) derived from HA 4 × CPI 60125 (HACPI 6). At LOD 2.0, 58 markers among 91 polymorphic markers were mapped on to 11 linkage groups (LG). The total length of the map spanned 2008.55 cM with an average density of 34.63 cM. Five QTLs, one controlling days to 50 % flowering, two each controlling dry seed yield plant-1 and test weight were detected based on each of the three years’ (Kharif-2014, Kharif-2015 and Kharif-2016) as well as three-years average quantitative traits data. One common QTL flanked by KTD 250 and LABT 2 with a distance of 37.69 cM controlling test weight was detected at 154 cM on LG 6 across Kharif-2014, Kharif-2015 and three-year’ average data. Another common QTL flanked by LABT 25 and LABRRT 43 with a distance of 41.12 cM controlling days to 50% flowering was detected at 41 cM on LG 9 across Kharif-2016 and three-year’ average data. The linkage of LABRRT 36 with QTL controlling days to 50 % flowering; KTD 63 with raceme length; LABRRT 36 with pods plant-1 and LABRRT 35 with dry seed yield plant-1 in HACPI 6-derived RIL population was confirmed in HACPI 3-derived RIL population. It is proposed to saturate the linkage map (of HACPI 6), confirm and validate the identified QTL for use in marker-assisted dolichos bean breeding.

    DYNAMICS OF QUANTITATIVE TRAITS IN F2 DERIVED FULL-SIB AND INBRED PROGENIES OF DOLICHOS BEAN [Lablab purpureus (L.) Sweet]
    (2014-07-05) CHANDRAKANT; RAMESH, S
    Taking the cues from beneficial effects of F2 bi-parental (BIP) mating in several self-pollinated crops, an investigation was carried out to assess the impact of inter se mating in F2 population derived from HA 4 (a high yielding photoperiod in-sensitive released variety) × GL 37 (a photoperiod sensitive germplasm accession) on quantitative traits mean, range, variance, additive genetic variance (σ2A), narrow-sense heritability (NS-h2) inter-relationships and frequency of transgressive segregants in Dolichos bean. F2 BIP mating derived (BIP F3) progenies and selfed (F3) progenies of parents of BIP mating were evaluated for 10 quantitative traits (QTs) at the experimental plots of Department of Genetics and Plant Breeding, UAS, GKVK, Bangalore following Augmented design during 2013 kharif season. Random mating in F2 population in Dolichos bean was effective in increasing the means, variances, σ2A and NS-h2 of traits such as racemes plant-1, fresh pods node-1, fresh pods plant-1 and fresh pod yield plant-1. BIP mating also resulted higher frequency of individuals that surpassed higher scoring parent for racemes plant-1, fresh pods node-1, fresh pod yield plant-1 and 100-fresh seed weight. The results suggested rapid genetic gain per selection cycle for longer-term and better prospects of deriving superior pure-lines with desired traits/combination of traits from inter-mated population. Further, significant shift in correlation coefficient of fresh pod yield plant-1 with racemes plant-1 from -0.33* (in F3 progenies) to 0.19 (in BIP F3 progenies) suggested the possibility of increasing the number of racemes plant-1 without penalty in fresh pod yield plant-1 through selection.
