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.

ThesisItem Open Access ASSESSMENT OF GENETIC VARIABILITY AND IDENTIFICATION OF ZINC RICH AND HIGH YIELDING GENOTYPES FROM COWPEA (Vigna unguiculata (L.) Walp.) GERMPLASM(University of Agricultural Sciences, Bangalore, 2022-01-17) PULIGUNDLA TH; Marappa, N.To assess genetic variability for yield and to identify zinc rich genotypes the present study was carried out using 263 cowpea germplasm accessions sown in augmented block design. Analysis of variance was significant for yield and its attributes indicating the sufficient variability among the genotypes used for study. Genetic variability estimates, PCV and GCV were found to be high for seed yield plant-1, moderate for clusters plant-1, pods cluster-1, pods plant-1 and 100-seed weight. Characters seed yield plant-1, 100-seed weight, pods plant-1 and clusters plant-1 recorded high heritability coupled with genetic advance as per cent of mean indicating the influence of additive genes in controlling these traits. Cowpea germplasm were grouped into 3 clusters following K-mean clustering maximum number of (167) accessions were grouped in cluster Ⅱ. Maximum inter cluster distance (53.20) was observed for cluster Ⅰ and Ⅲ and maximum intra cluster distance (22.70) was observed for cluster Ⅱ. The nearest cluster distance (46.4) was observed for cluster Ⅰ and Ⅱ and farthest distance (53.2) for cluster Ⅰ and Ⅲ. Sixty promising genotypes were used for estimation of zinc content. Germplasm accessions EC100087, IC426801 (Cluster Ⅰ) and EC18118 (Cluster Ⅲ) were identified as genetically divergent with zinc rich and high seed yield plant-1. These accessions could be used as parents in cowpea biofortification programmes.ThesisItem Open Access DEVELOPMENT AND EVALUATION OF INBRED LINES AND HYBRIDS FOR OIL YIELD AND QUALITY IN SUNFLOWER (Helianthus annuus L.)(University of Agricultural Sciences, Bangalore, 2020-10-21) VIJAYA KUMARA, L; Dr. SHADAKSHARI, Y GF1 hybrids are the major cultivar types used for commercial sunflower production. Use of genetically diverse parents is the key for development of broad based hybrids. Such hybrids contribute to sustainable sunflower production. Under these premises, an investigation was carried out to (i) identify high oil yield and oleic acid heterotic hybrids developed using existing inbred lines (ii) to develop and assess GCA of existing inbred lines for oleic acid and develop new inbred lines with high oleic acid content. A total of 50 hybrids, involving the existing 5 lines and 10 testers, along with parents and checks (KBSH-41, KBSH-44, KBSH-53 and RFSH-1) were evaluated during Kharif 2012 at Zonal Agricultural Research Station (ZARS), University of Agricultural Sciences,Bangalore. Three cross combinations, CMS 54A × RHA 23, CMS 54A × RHA-87and CMS 135A × RHA 23 were identified as desirable hybrids for seed yield plant-1, volume weight, 100 seed weight, oil content, oil yield and oleic acid content. Among the 50 hybrids, the best 15 hybrids were evaluated for stability across three seasons (kharif, rabiand summer). Four of these 15 hybrids, viz., CMS 58A × CSFI 5387, CMS 103A × RCR39, CMS 59A × CSFI 5387 and CMS 135A × RHA 23 were found stable across three seasons for all the characters. Three lines, CMS 103B, CMS 135B, CMS 58B and two testers CSFI 5387 and DRSF 106 were identified as high overall general combiners. A total of 412 and 423 plants were selected from B × B and R × R gene pools, respectively based on the allele specific SSR markers. The best ten of these lines were derived from two B × B gene pools (CMS 103B × CMS 135B, CMS 54B × CMS 103B) and three R × R gene pools (CSFI 5387× RCR 39, RCR 39 × RHA 87 and RCR 39 × CSFI 5387)ThesisItem Open Access COMBINING ABILITY OF EXOTIC ADVANCED BREEDING LINES (ABLs) IDENTIFIED AS PERFECT RESTORERS FOR FRUIT YIELD AND ITS ATTRIBUTING TRAITS IN CHILLI (Capsicum annuum L.)(University of Agricultural Sciences, Bangalore, 2022-12-06) PRASHANTHA, V; . MOHAN RAO, ACombining ability is one of the widely used criteria for selection of parents forhybrid cultivar development. Continuous use of new and diverse parents help broaden thegenetic base of hybrid cultivars which would eventually contribute to sustainable chilli U m , mb b l y x BL’ wusing line × tester mating design. Seventy-five chilli hybrids, their 20 parents and fivechecks were evaluated during early Rabi, 2021-22 for seven quantitative traits. Analysisof variance revealed significant differences among parents and crosses for all the sevenproductivity traits, justifying the material used in the study. Further, ANOVA ofcombining ability emphasized equal role of GCA and SCA variance in the inheritance offour of seven productivity traits; fruits plant-1, green fruit yield plant-1, average red fruitweight and red dry fruit yield plant-1 BL’ m ly, V , V V wfound good general combiners for most of the productivity traits. Top ranking hybridsexcelling the standard check, Arka Meghana for most productivity traits involved at leastone parent with good overall GCA status, establishing the reliability of selection of parentsbased on overall GCA status to realize heterotic hybrids. Two test hybrids namely, CMSUAA × AV 44 and CMS UAA × AV 43 registered high magnitude of heterosis overchecks for most of the productivity traits. These hybrids are suggested for extensiveevaluation in multilocation trials for confirming their yield uperiority and subsequentcommercialization.ThesisItem Open Access DETERMINATION OF DIRECTION OF PARENTS FOR USE IN CROSSES TO GENERATE VARIABILITY FOR FRUIT YIELD AND ITS COMPONENT TRAITS IN CHILLI (Capsicum annuum L.)(University of Agricultural Sciences, Bangalore, 2022-12-06) SHIRISHA, K M; MADHUSUDAN, KAssessing spectrum of variability among F2 populations derived from straight andreciprocal crosses helps to explore cytoplasmic influence, if any, on trait expression. Besidescytoplasmic effects, breeding potential differences between reciprocal cross derived progeniesassist in identifying the direction of use of parents in crosses to derive segregating populations.Under this premise, reciprocal cross differences, if any, between two sets of reciprocal crosses[(ADL-4 × S-343), (S-343 × ADL-4), (BD × S-343) and (S-343 × BD)] were assessed basedon trait mean, absolute range (AR), standardized range (SR), absolute phenotypic variance(σ2 p),phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV),transgressive segregation index (TSI) and Usefulness criterion (Uc). Further, breeding potentialof F2 populations derived from six crosses [(ADL-4 × S-343), (S-343 × ADL-4), (BD × S-343),(S-343 × BD), (AP × S-343), and (PDL-1 × S-343)] were assessed based on trait mean, AR,SR, PCV, GCV, TSI and Uc at one and five per cent selection intensities. For productivitytraits, F2 populations derived from two sets of reciprocal crosses differed significantly. F2populations derived from S-343 × ADL-4 and S-343 × BD displayed higher mean, TSI and Ucfor green fruit yield plant-1 than its reciprocal cross. Breeding potential of F2 population derivedfrom S-343 × ADL-4 irrespective of the direction of cross was better than those derived fromremaining crosses for green fruit yield plant-1. The study suggests the need to use S-343 asfemale parent to enhance variability for fruit yield and its component traits.ThesisItem Open Access GENETIC VARIABILITY FOR GAMMA RAYS INDUCED MUTAGENESIS FOR PRODUCTIVITY PER SE TRAITS AND MALE STERILITY IN ADVANCE GENERATIONS OF RAGI (Eleusine coracana L. Gaertn.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-07-22) PRASHANT VASISTH; RANGAIAH, S.important traits. Therefore, an investigation was aimed to study the gamma rays induced mutagenesis for male sterility and productivity traits in ragi. M3 seeds suspected for partial male sterility of two irradiated genotypes, GPU 28 with 3 doses (300,400,500 Gy) and KMR 204 with 2 doses (300,400 Gy) were used in present study. Screening for pollen sterility was done using acetocarmine test in M3 generation and observations were recorded on ten quantitative traits (except for sterile plants). Seventy six partial sterile mutants were identified having above 70% pollen sterility, were forwarded for evaluation of progenies in two experiments. In experiment (a) Sixty three (31 from M3 –GPU 28 and 32 from M3 –KMR 204) were evaluated in progenies phenotypically and 43 progenies were non segregating (fertile), 20 were segregating for fertility in M4 of GPU 28 and KMR 204. In experiment (b) a total of 13 partial sterile mutants (6 from M3 –GPU 28 and 7 from M3 –KMR 204) were evaluated in M4 and found 9 mutants with both male and female sterility. Fifty eight mutants (31 from M3 –GPU 28 and 27 from M3 –KMR 204) were advanced from M3 to M4 for the evaluation for yield. Ten M4 families (5 from M4 – GPU 28 and 5 from M4 –KMR 204) and 20 individual mutants (11 from M4 –GPU 28 and 9 from M4 –KMR 204) were found in M4 generation having higher seed yield than checks.ThesisItem Open Access ASSOCIATION OF MORPHOLOGICAL CHARACTERS AND DEVELOPMENTAL STAGES WITH GREEN POD AND DRY SEED YIELD IN Phareolus oulgaris L.(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1996-11-15) PRAKASH, K.S.; Hari Har Ram, Dr.ThesisItem Open Access MUTAGENIC RESPONSES OF GRAIN AMARANTHUS (Amaranthus cruentus L.)
