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.

    GENETIC ANALYSIS FOR FRUIT YIELD AND YIELD COMPONENTS AND TAGGING TRAITS RELATED TO WATER USE EFFICIENCY IN TOMATO (Solanum spp.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2018-12-07) SURESH, K; SAVITHRAMMA, D. L.
    The present investigation was carried out to assess the variability and diversity for traits to water use efficiency and fruit yield in tomato germplasm during 2013 at GKVK, UAS, Bengaluru. The study revealed moderate to high PCV and GCV in most of the traits studied. K-mean cluster analysis revealed high level of morphological diversity as indicated by diverse clusters which is informative for breeding programs. Drought tolerance analysis identified MP, GMP, HAM and STI as more effective indices and EC 677068, EC 608271, EC 676792, EC 586980 and EC 676783 as most drought tolerant accessions. Further, twelve inter-specific hybrids developed from seven parents selected on basis of SCMR, SLA and Δ 13C were evaluated in RCB design during Kharif 2014. The parents EC 771612 and LA 2567 and crosses VRCT 174 × EC 519100, EC 771597 × EC 771612 × LA 2657 recorded significant gca and sca effects for most of traits related to WUE and fruit yield respectively. Moderate to high coefficient of variability was noticed in F2 and F3 populations of cross EC S. lycopersicum cv. EC 771612 × S. pennellii cv. LA 2567 and positive platykurtic skewed distribution indicating dominance based complementary gene interaction in the inheritance of traits studied. Five generations of the cross EC 661257 × LA 2657 revealed additive gene effect (d) and presence of duplicate dominant epistasis in all the traits except specific leaf area. Out of 212 SSRs surveyed for polymorphism only 24 were found to be polymorphic between the parents and were used in Bulk segregant analysis. SSR 19 and SSR 218 showed putatively linkage to SCMR and SLA respectively, can be used for selection of high water use efficient genotypes.

    GENETIC AND PHYSIOLOGICAL STUDIES FOR SEED YIELD AND YIELD ATTRIBUTING TRAITS IN COWPEA [Vigna unguiculata (L.) Walp.]
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-10-23) LOKESH, G. Y.; Niranjana, Murthy
    Investigation was carried out in cowpea at Dry Land Agriculture Project, GKVK, UAS, Bangalore during 2008-2010 to study the variability and five generation mean analysis for days to first flowering, days to maturity, plant height, primary branches and secondary branches per plant, pods per plant, pod length, seeds per pod, seed yield per plant and test weight in three crosses of cowpea viz., IT-38956-1 × KBC-2, IT-38956-1 × CP-12 and KBC-2 × CP-12. In addition, the genetic variability parameters and character association studies for the two physiological traits viz., specific leaf area and spad chlorophyll meter reading were studied in the F3 for the cross IT-38956-1 × KBC-2. The mean and variance in three F2 populations of ten quantitative characters indicated wide variability for plant height, days to maturity, pod length, seeds per pod and seed yield per plant. Moderate to high GCV, PCV, genetic advance and heritability were observed for plant height, secondary branches per plant, pods per plant, seeds per pod and seed yield per plant in all three crosses. Significant and high positive correlation for seed yield per plant with secondary branches per plant, pods per plant, pod length and seeds per pod were observed in all three crosses. Five generation analysis in three crosses indicated non-additive gene action. Minimum number of effective factors ranged from one to five pairs. Potence ratio indicated the presence of over-dominance and partial dominance in maximum traits. SLA and SCMR has showed week association with the seed yield.

    ANALYSIS OF MORPHO-MOLECULAR DIVERSITY, COMBINING ABILITY AND STABILITY IN MAIZE (Zea mays L.)
    (University of Agricultural Sciences GKVK, Bangalore, 2013-11-20) VIVEK, B. C.; Lohithaswa, H. C.
    An investigation was carried out at ZARS, V.C. Farm, Mandya; ARS, Bavikere and Farmer's field, Yatnahalli village, Ranibennur Tq. to analyze the morphological and molecular (SSR) diversity, combining ability of inbreds and stability of hybrids for 16 morphological characters during kharif 2012. Pooled analysis of variance revealed significant differences among 100 inbreds and 225 hybrids for all the 16 characters. One hundred inbreds were grouped into 10 clusters and cluster I (48) accommodated maximum number of inbreds. The character days to brown husk contributed highest for total divergence and the inbred MAI- 706 recorded highest mean values for more number of characters. At the molecular level, inbreds were grouped into seven clusters and cluster III was the largest with 35 entries. A total of 213 SSR alleles were detected and the marker umc2078 sampled highest number of alleles and maximum PIC was observed for umcl542. There was no agreement between morphological and molecular diversity. Predominance of additive genetic variance was noticed for characters grain yield, test weight, grain rows per cob, cob length and cob girth. The inbreds LM-13,V-1712-1, V-1154 and CIMMYT-5 were good general combiners and the crosses MAI-117 x LM 13, Z-62-67 x MAI 105 and Z-62-55 x LM 13 were good specific combiners.The crossesCIMMYT-5 x LM 13, LTP-1 x SKV 50 and CIMMYT-5 x SKV 50 manifested significant standard heterosis for highest number of characters.The test hybrids V-2232 x MAI 105, V-1649 x MAI 105, CIMMYT-5 x LM 13, V-1712-1 x MAI 105, Z-63-30 x LM 13, V-632-112 x LM 13, V-1168 x LM 13, V-291-2 x LM 13, V-632-67 x LM 13, CML-172 x MAI 105, V-1154 x LM 13, V-241-2 x LM 13, CIMMYT-47 x LM 13, Z-51-1 x LM 13, HKI-193-1 x LM 13, V-2232 x LM 13 and V-1649 x LM 13 were stable with high grain yield and could be further evaluated for confirmation of their superiority.
