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 SEED PHYSIOLOGICAL QUALITY OF SUNFLOWER (Helianthus annuus L.) HYBRIDS FOR ABIOTIC STRESSES
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-12-27) YASHASWINI., B; DEVARAJU, P. J.
    Sunflower seed production affected due to biotic and abiotic stresses. High drought and salinity are common environmental problems which affecting seed germination and plant growth especially in arid and semi-arid regions. Sunflower is an oilseed crop rated moderately salt and drought tolerant crop, but it is sensitive to salt and drought at germination and seedling stages. The effect of salt stress (NaCl) and water stress (PEG-6000), on germination and early seedling growth was studied KBSH-1, KBSH-41, KBSH-44 and KBSH-53 of sunflower hybrids. Among hybrids, highest germination and seedling emergence was observed in KBSH-44, while at -0.6 M Pa concentrations of PEG-6000 were found to be critical lethal dose for all the characters. Among hybrids, the highest germination and seedling emergence was observed in KBSH- 1, whereas increased salt concentration rendered in germination and seedling growth. Plant growth also decreased with increasing PEG concentrations. In addition, there were differences between the sunflower hybrids in terms of their response to drought and salinity. Among the hybrids, highest seed yield per plant was observed in KBSH-44 in PEG induced stress and the seed yield per plant found to be significant under non moisture stress condition than moisture stress conditions. Among the hybrids highest seed yield per plant was recorded in KBSH-1 (H1) in salinity stress.

    CHARACTERIZATION AND IDENTIFICATION OF CULTIVARS BY USING BIOCHEMICAL AND MOLECULAR MARKERS IN RICE (Oryza sativa L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-11-11) RANJITHA, H. P.; RAME, GOWDA
    Genetic purity assessment is an important criteria in seed production and seed certification programme. Therefore, simple and reliable techniques need to be developed for variety identification and seed genetic purity testing. An attempt was made to characterize thirty rice cultivars and hybrids along with their parental lines based on their morphological, biochemical and molecular markers during 2014 to 2017. Seed morphological characters were used for the broader classification of rice. Both standard and modified phenol tests with FeSO4 and CuSO4 were found effective in identifying some of the rice cultivars like MSN-36 (R) from CRMS-32(A) and KRH-4. Besides, KOH test was useful in identification of red kernel cultivars like CTH-1, CTH-3, JGL- 1798 and Jyothi. The zymogram of total soluble seed protein found to be useful in distinguishing the rice cultivars, parental lines and hybrids based on the relative intensity and mobility of bands. Among the tested isozymes, alcohol dehydrogenase (ADH) banding pattern found useful in differentiating the cultivars like CTH-1, IR-30864 and IR-64 at Rm value of 0.54 based on the intensity of bands. Out of 84 markers studied, 63 markers found to be polymorphic and 37 markers were unique for the cultivars and parental lines used in the study. These cultivar specific markers found useful for cultivar identification and characterization. Seven markers were confirmed hybridity of KRH-2 with its parental polymorphism and in case of KRH-4, 20 markers were confirmed hybridity of KRH-4 with its parental polymorphism. Unique markers were identified for the KRH-2 (RM164 and 263) and KRH-4 (RM21, RM 1385, RM 444 and RM 400). These primers can be effectively used for genetic purity assessment in KRH-2 and KRH- 4. This was the unique study to assess the genetic purity of these line at the seed/seedling stage and very useful in rice hybrid seed industry.

    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-11-02) HARISH, M.S.; RAME, GOWDA
    In view of the wide spread cultivation of groundnut in India and in other parts of the world, both laboratory and field experiments were carried out to examine the influence of seed treatment with nanoparticles on ‘morpho physiological and biochemical changes in groundnut (Arachis hypogaea L.)’ during 2014-15 and 2015-16. In laboratory experiment, medium vigour groundnut seeds were separately treated with four nano particles and four bulk micro nutrients viz., nano Zinc Oxide (ZnO), FeO NPs, CaCO3 NPs, TiO2 NPs and Bulk ZnO, Bulk FeO, Bulk CaCO3, Bulk TiO2 . Among the different treatments imposed, seed treatment with nanoscale ZnO (25 nm) @1000 ppm significantly promoted seed quality attributes of germination (82%), root length (9.02 cm), shoot length (18.7 cm) and SVI (2280), SVI-II (1903), TDH (0.40 A480 nm) with lower seed infection (6.75%) when compared to control (64%, 6.75 cm, 14.28 cm, 1349, 1117, 0.34, 16.17%, respectively, for above parameters). Besides, the positive impact of nanoparticles seed treatment was also observed for the changes in biochemical attributes both in laboratory and pot culture experiments. The amylase activity (22.97 & 23.97 mm), peroxidase activity (0.30 & 0.28 μmol/ml) super oxide dismutase (8.23 & 9.67 unit/mg) catalase activity (0.32 & 0.39 μmol/ml) were found to be higher in Zinc oxide nanoparticles @ 1000 ppm compared to control (20.73 & 20.53 mm, 0.27 & 0.22, 7.93 & 7.67 unit/mg, 0.3, 0.3 μmol/ml). In field experiment, plant growth parameters viz., field emergence (82.9%), plant height at 45DAS, 60DAS, harvest (21.78, 28.86, 37.33 cm), number of branches at 45, 60, 90 DAS (4.82, 5.72 & 6.78), days to initiation of flowering (25 days) and yield parameters like, pod yield plant-1 (29.2 g), number of pods plant-1 (23.5) and haulm yield plant-1 (192 g) SMK % (88 %), shelling per cent (79.6) also differed significantly with ZnO (25 nm) @1000 ppm compared to traditional source of Zn application with ZnO @ 30 g/15 liter of water + RDF with the foliar application and seed application. The inhibitory effect noticed with higher dose of nanoparticle @2000 ppm suggested the need of judicious usage of these nano-particles in such applications. The first ever report on the effect of nanoscale elements on plant growth and yield of groundnut revealed the positive influence and that could be used as seed treatment to enhance yield and quality of seeds.

    MAXIMIZATION OF SEED YIELD AND QUALITY OF PADDY (Oryza sativa L.) THROUGH ANTIOXIDANTS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-21) LOKESH, K. S.; VISHWANATH, K.
    Rice (Oryza sativa L.) is a “Global Grain” cultivated widely across the world and feeds millions of mankind, is the staple food for more than half of the human population. In Asia alone more than two billion people depend on rice and its products for their food intake. Rice being grown in Asia for at least 10,000 years and it has become deeply embedded in the cultural heritage of Asian societies and is the life, heart and soul of the people throughout Asia. It can be considered as “Rice Basket” of the world, as 90 per cent of world‟s rice is grown and consumed by 60 per cent of the population and where, about two-thirds of world‟s poor live (Khush and Virk, 2005). Only 4-5 per cent of world rice production enters the global market. Hence, any shortfall in rice production especially in the major rice growing countries could be disaster for food security. World acreage under rice cultivation is 158.8 m. ha. with a production of 738.2 m. t. (FAO, 2015). In India, rice is the second most produced commodity cultivated on an area of 43.95 m. ha. with production and productivity
