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 BIOCHEMICAL PARAMETERS IN BAMBARA GROUNDNUT
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK, BENGALURU, 2019-08-19) CHANDANA, B. S.
    Bambara groundnut is an important underutilized crop rich in protein and comparable to cowpea and groundnut having nutritional benefits and also has certain constraints like presence of antinutritional factors which hinder its utilization. The present investigation was conducted to study the nature and magnitude of genetic variability and identification of protein rich genotypes with lower levels of antinutrional factors in bambara groudnut. Thirty genotypes were sown in kharif 2018 in experimental field plots of Genetics and Plant Breeding UAS, GKVK, Bengaluru. The genopypes were evaluated by following RCBD design with five replications and observations for ten quantitative traits were recorded. Analysis of variance revealed significant differences among all the genotypes. The estimates of genetic variability parameters and heritability coupled with genetic advance were higher for most of the characters. Grouping of genotypes into clusters using Tocher’s method resulted in the formation of 4 clusters. Thirteen out of thirty genotypes were selected for nutritional and antinutritional estimation. Analysis of variance for nutritional and antinutritional factors revealed significant differences among the genotypes. Protein content was highest for S-165A and lowest for SG-8. Antinutrients such as phenol content was lowest for SG-7 and highest for S-165A, phytic acid content was lowest for SG-8 and highest for DODRTZ, tannin content was lowest for SG-7 and highest for S-165A. The genotypes such as S-165A, uniswa red, SG-7 had high yield and high protein content. SB-42 derived mutant SG-7 had higher yield, higher protein and lower levels of phenol, phytic acid and tannin content.

    IDENTIFICATION OF DIAGNOSTIC MOLECULAR MARKERS FOR GENETIC PURITY TESTING IN COWPEA [Vigna unguiculata (L.) Walp.]
    (University of Agricultural Sciences, Bengaluru, 2018-09-08) CHANDANA, B. S.; Nethra, N.
    Genetic purity is one of the important quality criteria required for successful seed production and seed certification. Hence, the experiment was set to evaluate the usefulness of SSR markers to determine genetic purity of commercial seed lots of cowpea, which are present in the seed chain of Karnataka. Out of 55 SSR markers studied, 10 SSR markers showed polymorphism for each of the 7 varieties, which revealed 25 alleles at 10 loci with an average of 2.5 alleles per locus. The SSR 6292 showed the highest number of alleles with the PIC value of 0.71. PKB-4 cultivar was found to be most divergent from dendrogram constructed by UPGMA clustering. The genetic purity of the seed lots was tested by following the 20 × 20 matrix, where the purity levels recorded cent per cent for all the seed lots except for KBC-2, IT-38956-1 and C-152 varieties, for which the purity levels are 98%, 96% and 97%, respectively. This analysis revealed that SSR marker is a potential tool for fingerprinting of varieties as well as for the genetic purity testing of the seed lots. Thus, it is helpful for delivering pure seed lots to the farmers.
