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.

    Line x Tester analysis for yield and bacterial wilt resistance in green brinjal (Solanum melongena L.)
    (University of Agricultural Sciences GKVK, Bangalore, 40865) MURTHY RAMIREDDY, S. R. K; LINGAIAH, H. B
    The study entitled Line x Tester analysis for yield and bacterial wilt resistance in green brinjal (Solanum melongena L.) with the objectives of estimating magnitude of heterosis, combining ability effects and to identify the resistant sources for bacterial wilt resistance. The experimental material comprised of three lines viz., Arka Shirish, Mattugulla and Arka Kusumakar and four testers viz., IIHR-3, IIHR-7, WCGR and SM6-6 in Line x Tester mating design. Wide range of heterosis was manifested by the 12 F1 hybrids for all the characters. Among the 12 hybrids, 7, 4 and 1 hybrids exhibited significantly positive heterosis for fruit yield per plant over mid parent, better parent and commercial check, respectively. Maximum positive significant heterosis was observed in the cross Arka Shirish x WCGR (84.93%) over mid parent, Arka Shirish x WCGR (60.71%) over better parent and Arka Shirish x IIHR-7 (31.02%) over commercial check. The hybrid Mattugulla x WCGR exhibited highly significant heterosis for number of fruits/cluster and number of flowers per cluster while the same hybrid Mattugulla x WCGR showed significant heterosis for average fruit weight. Combining ability analysis revealed that the majority of the characters were under the control of non additive gene action as SCA variances were greater than GCA variances. Highly significant variation was observed due to genotypes and environments for all the 16 characters studied. Both gca and sca variances showed significant interactions. The genotypes Arka Shirish, Arka Kusumakar, IIHR-7 and SM6-6 were found to be good general combiners and Arka Shirish x IIHR-7 was identified as best specific combiners for fruit yield and other related traits as it showed high sca effect and per se performance (2.01 kg). For bacterial wilt disease, Mattugulla x WCGR and Mattugulla x SM6-6 were identified as best as they showed high resistant reaction

    EVALUATION OF F1 HYBRIDS IN ORIENTAL PICKLING MELON (Cucumis melo var. conomon)
    (University of Agricultural Sciences GKVK, Bangalore, 40768) THYAGARAJ, G. N; PUTTARAJU, T. B
    Oriental pickling melon is one of the melon group vegetable of the Cucurbitaceae. In Karnataka it is called by local name as samber southe or Mangalore southe. Which contain moderate amount of vitamins and minerals and the fruits possess cooling properties and are used as a skin moisturizer and as a digestive agent. Present field experiment was carried out at Department of Horticulture, GKVK, UAS, Bengaluru during the year 2010-2011 to evaluate 25 Oriental pickling melon F1 hybrids for yield, quality and pest and diseases. The F1 hybrid CMC GKVK 1 X CMC GKVK 2 have shown better performance for characters such as fruit length and fruit diameter, while the F1 hybrid CMC GKVK 2 X CMC GKVK 4 performed well for other characters such as per cent fruit set, number of fruits, total fruit yield per vine and also it was moderately resistant to powdery mildew. However, the fruit flesh thickness and total soluble solids where high with the F1 hybrid CMC GKVK 1 X CMC GKVK 12. Finally it can be inferred that among the F1 hybrids CMC GKVK 2 X CMC GKVK 4, CMC GKVK 1 X CMC GKVK 2, CMC GKVK 5 X CMC GKVK 8 and CMC GKVK 9 X CMC GKVK 2 were high yielding. For the purpose of processing F1 hybrids CMC GKVK 1 X CMC GKVK 12, CMC GKVK 7 X CMC GKVK 9, CMC GKVK 1 X CMC GKVK 2 and CMC GKVK 2 X CMC GKVK 4 were suitable.

    GENETIC VARIABILITY STUDIES IN SNAKE GOURD (Trichosanthes cucumerina L.)
    (University of Agricultural Sciences GKVK, Bangalore, 26-08-11) PADMARAJA, S. R; PUTTARAJU, T. B
    Snake gourd is an important cucurbitaceous vegetable having considerable nutrition and medicinal properties. The present study was undertaken to elicit information on the nature of variability, correlation and path analysis of snake gourd genotypes during 2010-2011 at Department of Horticulture, UAS, GKVK, Bangalore. The analysis of variance indicated highly significant variation among the genotypes for all the characters. The phenotypic co-efficient of variation was more than the genotypic co-efficient of variation for almost all the character under study. Both growth and yield attributing characters like number of primary branches per plant, productive length of vine, number of nodes per vine, inter nodal length, node at which first female flower appearance, number of fruits per plant, mean fruit weight, fruit length, fruit girth, flesh thickness, size of the cavity, number of seeds per fruit, fruit fly infestation, downy mildew incidence and yield per plant showed high genetic advance over per cent mean with high heritability. Yield per plant was positively and significantly correlated with vine length, productive length of vine, number of fruits per plant, mean fruit length and fruit weight at both genotypic and phenotypic levels. Path analysis revealed mean fruit weight, number of fruits per plant contributed positive direct effect on fruit yield and other growth and fruit related characters contributed indirectly through fruit yield. The genotypes GKVK SG-16, GKVK SG-7, GKVK SG-13, GKVK SG-8 and GKVK SG-14 were found to be early flowering and higher yield per plant. The genotypes GKVK SG-9, GKVK SG-8, GKVK SG-14, GKVK SG-5, GKVK SG-13, GKVK SG-7 and GKVK SG-16 were found to be moderately resistant to fruit fly and downy mildew disease.

    EVALUATION OF ADVANCED POTATO (Solanum tuberosum L.) HYBRIDS FOR GROWTH AND YIELD IN SOUTHERN TRANSITIONAL ZONE OF KARNATAKA
    (University of Agricultural Sciences GKVK, Bangalore, 40828) SANTHOSH, N; INDIRESH, K M
    Potato (Solanum tuberosum L.) is one of the world’s most important food crop. A study was conducted at Agricultural Research Station, Madenur, Hassan, during kharif-2010. Two experiments consisting of evaluation of early and medium maturing advanced potato hybrids were carried out. Among early maturing advanced potato hybrids, high GCV and PCV were observed for plant height, number of stems, number of tubers per plant, marketable and total tuber yield. High heritability coupled with high GAM were observed for plant height, number of tubers per plant, marketable and total tuber yield, tuber diameter, non-reducing sugars, potato leaf roll virus and Spodoptera. Path co-efficient analysis revealed that plant height, number of leaves, number of tubers per plant, tuber weight per plant and marketable tuber yield at both genotypic and phenotypic level had a positive direct influence on the yield. Genotypes J/97-168 and Kufri Pukhraj performed well under southern transitional zone of Karnataka. Among medium maturing advanced potato hybrids, high GCV and PCV were observed for plant height, number of stems, number of tubers per plant, marketable and total yield and total sugars. High heritability coupled with high to moderate GAM were observed for all the characters except chlorophyll content. Path co-efficient analysis revealed that number of stems, number of leaves, number of tubers per plant, tuber weight per plant and marketable tuber yield at both genotypic and phenotypic level had a positive direct influence on the yield. Genotypes 200/P-26, MS/99-1871 and Kufri Pukhraj performed well under southern transitional zone of Karnataka.
