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.

V.An investigation was carried out at ARS, Mugad involving 25 native "and improved genotypes of rice to estimate the extent of fertility restoration 'by different genotypes and to identify maintainers and restorers for the two CMS lines, wz., IR58025A and IR62829A. An assessment of heterosis for yield and yield attributing characters in the hybrid combinations involving effective restorers as one of the male parents was done. A wide range was observed for the extent of restoration in both the CMS lines, assessed in terms of pollen and spikelet fertility. A highly significant correlation was observed between pollen fertility and spikelet fertility. The ability of fertility restoration differed in a given genotype with the CMS lines, indicating change in the penetrance and expressivity of fertility restoring genes according to the nuclear background of male sterile parent. However, a restorer and three maintainers did not exhibit this type of nuclear-cytoplasmic interaction. Out of the 25 native and improved rice genotypes screened against WA'®type CMS lines, for IR58025A, Antarsali and Champakali restored the fertility effectively and in case of IR62829A, Beeraga, Champakali and Jeerasali were the effective restorers. Three genotypes wz., Gopaldoddiga, Huggibhatta and Ptb-7 were effective maintainers for both the CMS lines. Most of the hybrids studied involving effective restorers as one of the parents exhibited positive heterobeltiosis for long duration, tallness, jiroductive tiller number and length of panicle. But in certain hybrid ppmbinations due to different degree of spikelet sterility in the hybrids, these characters do not reflect as increase in yield per plant. All hybrids studied showed significantly positive standard heterosis considering Amrut as the standard check variety. This indicates the potentiality of the hybrids for possible commercial utilization. Among the five hybrids studied, IR62829A/ Beeraga, 1R62829A/ Jeerasali and 1R58025A/ Antarsali were found to be promising.ThesisItem Open Access EVALUATION OF SPANISH TYPE GROUNDNUTS FOR RESISTANCE TO STEM-AND POD-ROT CAUSED BY Sclerotium rolfsii Sacc.(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) KRISHNAKANTH, A.; CHANNABYRE GOWDA, M.V.SderotiuTn rolfsii incited stem and pod rots is a major constraint to groundnut productioa in many groundnut growing regions of India, Though considerable research has been carried out on the management of the disease, information on the reaction of the currently grown Spanish type cultivars to the fungus in India is larlring Evaluation of 13 genotypes along with resistant (ICGV 86590 and GBFDS 272) checks under artificially inoculated conditions indicated significant difference among genotypes and seasons as well as genotype x season interaction for disease, yield and yield related parameters. M^'ority of ruling Spanish type cultivars of Karaataka (TMV 2, JL 24, Dh 40, KRG 1 and R 8808), two germplasm lines (ICG 5125 and ICG 5247) and three leaf spot resistant Spanish mutants {VLl-28-2, VLl-45 and VLl-llO) were susceptibie, while a released cultivar Dh 8 was comparable or superior to the resistant checks. To assess the scope for selection in hybrid populations, two crosses were generated using JL 24, a popular but susceptible Spanish type cultivar and Dh 8, a resistant but deficient in shelling outturn and hundred seed mass. The crosses exhibited significant variability for all characters and it was highly heritable for disease inadence and yield per unit area. The fi^quency of superior sregants were high for disease resistance (48%), but low for shelling outturn (7%) and hundred seed mass (11 %) leading to recovery of very few desirable lines. None of the genotypes tested in the present study was completely resistant. Other controal measures (cultural, chemical and biological) when applied individually are known to be incompletely effective, necessitating integration of different approaches to achieve effective control of the pathogen.

Apical meristems (domes) were used as explants. Among three levels of BA used, one with 2 mgT* resulted in maximum estabhshment of the meristem culture in all three cultivars. Out of the various combinations and concentrations of BA and NAA tried, the treatment 1.0 mgl"' BA was found to result in reasonably high average rate of shoot multiplication (6.26) across all the cultivars and the shoots were also of desirable quality. The treatment with 2.0 mgl"' BA gave the highest average rate of shoot multiplication (20.09). But the plantlets were very tiny, weak and non-separable. All four sources of sucrose, viz., analytical grade, laboratory grade, diamond sugar and ordinary (commercial) sugar were found to be equally effective for shoot multiplication in all three cultivars studied. The sucrose at 30 gl'* resulted in the highest over all shoot multiplication rate (5.40), which is significantly superior to other concentrations. Alternative supportive agents, viz., peat, sand and sabudani were unsuitable as supportive agents as a replacement for agar in producing desired rate of shoot multiplication. Very high rooting frequency was observed with 0.5, 1.0 and 2.0 mgl"' NAA in all three cultivars. Good response was also observed with plain MS and 0.25 mgl* NAA. The survival of the potted plants during rainy season in an uncontrolled glasshouse with RH of 88 per cent was maximum (94%) for the cultivar 'Co 8014' followed by 'Co 85002' (88%) and 'CoC 671' (72%).ThesisItem Open Access NATURE OF GENE ACTION FOR AGRONOMIC TRAITS IN TWO CROSSES OF PROSO MILLET (Panicum miliaceum L.)(University of Agricultural Sciences, Bangalore, 1997) H U, UMASHANKAR; GOWDA, B T SHANKAREAbstract not availableThesisItem Open Access IN VITRO REGENETRATION OF PLANTLETS AND STUDY OF SOMACLONAL VARIATION IN LITTLE MILLET (Panicum sumatrense Roth.)
