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 DIVERSITY OF Sclerotium rolfsii Sacc. AND SCREENING OF GROUNDNUT COLLECTIONS AGAINST STEM ROT DISEASE
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2019-09-06) SACHIN HAWALADAR; Jahir Basha, C. R.
    Studies on diversity of Sclerotium rolfsii Sacc. and screening of groundnut collections against stem rot disease were carried out during 2018-19 at the Department of Plant Pathology, University of Agricultural Sciences, Bangalore. Survey was conducted in major groundnut growing districts of Karnataka to know the prevalence of groundnut stem rot disease. The disease is prevalent in the entire groundnut growing areas surveyed with maximum (18.65 %) and minimum (11.63 %) incidence recorded in Bagalkot and Dharwad district, respectively. Ten isolates of Sclerotium rolfsii were collected from different locations of Karnataka and its variability were studied. The morphological and cultural characters of these isolates varied with respect to their growth rate, time taken to initiate sclerotia, size and weight of sclerotial bodies. Guledagudda isolate (SrB2) produced largest sclerotial body (2.33 mm) and Madhugiri isolate (SrT2) proliferated much faster compared to other isolates (12 days). Variability of these isolates were analyzed by amplifying and sequencing the ITS rDNA region. Among the ten isolates, seven isolates viz., SrY1, SrY2, SrD1, SrD2, SrC1 and SrT1 shared more per cent identity with Athelia rolfsii, two (SrB2 and SrC2) share more identity with Sclerotium delphini and two (SrB1 and SrT2) share identity with both Athelia rolfsii and Sclerotium dolphini. The groundnut genotypes were screened against the stem rot disease to identify the resistance source. Among the 31 genotypes screened in disease sick plot, 15 genotypes were moderately resistant with disease incidence ranging from 10.10-30.00 per cent, 15 genotypes were susceptible and one genotype TMV-2, was highly susceptible.
