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 VARIABILITY ANALYSIS IN JACKFRUIT (Artocarpus heterophyllus Lam.) GENOTYPES WITH DIFFERENT PULP COLOURS USING RAPD MARKERS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-01-12) ABIO, MARAK; Shyamalamma, S.
    Jackfruit is an important underutilized Horticulture crop, suitable for dry regions. The fruits are rich in several minerals, vitamins and flavonoids. The genetic diversity in terms of fruit size, shape, pulp colour, taste, aroma and yield of fruits is huge. This genetic variability can be exploited for selection and crop improvement. Thus, in the above study on genetic variability in Jackfruit genotypes with four different pulp colours viz, cream, yellow, light orange and deep orange was carried out for morphological traits. The fruit weight varied from 4.60 to 29.66 kg. Number of flakes per kg fruit varied from 11.33 to 26.66, the weight of flakes per kg fruit also varied significantly among genotypes. The higher weight was recorded in Byrachandra (710 g), NKT 2 (656.66 g), Swarna halasu (619.66 g) and KT 3 (612.33 g). The seed weight was lower in NKT 3 (27 g), KT 7 and KM 2 (40.33 g). The average seed weight was 76.60 g. The Jackfruit genotypes with different pulp colours were screened using RAPD marker to assess genetic diversity. The study, revealed that the RAPD markers OPAH 4, OPAH 5, OPP 1, OPP 4, OPP 5, OPP 6, OPP 7, OPN 1, OPA 2 and OPA 3 amplified distinct polymorphic markers in genotypes with cream colour pulp. Similarly the RAPD markers OPAH 20, OPP 4, OPP 5, OPP 6, OPN 1 and OPA 7 amplified distinct fragments in Jackfruit genotypes with deep orange pulp colour. These markers can be further screened for development of SCAR markers linked to pulp colour.
