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.

    Studies on Physiological, Biochemical and Molecular changes associated with seed priming in Maize hybrids (Zea mays L.)

    The present study was conducted to standardize the hydro-priming protocol in two maize hybrids viz., Hema and Nithyashree to know the physiological, biochemical and molecular changes associated with priming in maize seeds. The crop specific efficacy of different combinations of temperature and duration of soaking were standardized based on the performance of seed quality attributes and the best priming temperature was 25±10C, optimum duration of soaking was 24h. All the physiological attributes such as first count germination, final count germination, T50, BRI, MSL, MSDW, SVI-I and SVI- II were significantly higher (82%, 90%, 2.64 days, 0.409, 32.83cm, 6.05mg, 2990, 549, 81% and 81%, 90%, 2.39 days, 0.406, 32.08 cm, 5.77mg, 2925, 526, 79% in Hema and Nithyashree respectively). Biochemical attributes such as TDH, TSP and DNA content were significantly higher (2.293, 282.58 μg/g, 44.45 μg/g and 2.074, 268.29 μg/g, 42.30 μg/g respectively in Hema and Nithyashree respectively). Whereas, EC and TSS activity were significantly lower (209.9 μSm-1, 145.37 μg/ml, and 200.52μSm-1, 142.17 μg/ml) in both hybrids. The ability to distinguish and identify the hybrids is fundamental for the operational aspects in the seed trade. SSR molecular markers were employed to distinguish the hybrids and their parental lines. Among 48 SSR markers Only five viz., bnlg 1018, p-phi 435417, Umc 1388, UMC 2362 and Phi 001 were found to be polymorphic between hybrids and its parental lines. Based on the complementary banding pattern between the hybrids and their parents the SSR marker bnlg 1018, P-phl 435417, Umc 1388 were identified as specific markers to distinguish F1 maize hybrids. The SSR primers UMC 2362 and Phi 001 were identified as more useful primers which can differentiate the Hema hybrid from Nithyashree and also from other hybrids. The chemical method of varietal identification needs to be standardized and can be successfully employed with other reliable methods of varietal identification.
