The present study has been carried out to characterize twenty four horse gram genotypes through morphological and molecular techniques at the University of Agricultural Sciences, Dharwad during kharif season of 2015 and the molecular characterization were carried out in the laboratory of Institute of Agri-Biotechnology. Based on the seed coat colour and the biochemical tests carried out, the genotypes were grouped into four groups viz. brown, light brown, dark brown and black colour (PHG-04). In case of plant growth pattern, all the genotypes were spreading type of growth habit and indeterminate type of growth pattern and further, the variation could not be observed in case of raceme position and leaf pubescence. The wide variation was observed for various phenotypic and yield characteristics such as pod colour, number of pods per plant (123.07 - 233.67), pod initiation (49.8 - 70.67 days), pod length (3.97- 4.83 cm), number of seeds per pod (4.33 – 6.00), pod shattering, pod pubescence, pod curvature, pod maturity (82.73- 123.67 days) and seed yield (8.8- 20.57 g) among 24 horse gram genotypes and were grouped into different categories. The molecular data of 24 varieties using eleven primers revealed monomorphic bands suggesting low genetic diversity and high genetic kinship due to the autogamous nature of pulses.ThesisItem Open Access Influence of Sowing Dates on Seed Setting, Yield and Quality of RABI Sorghum Genotypes(University of Agricultural Science, Dharwad, 2017-07) Chaithra V.; Uppar, D.S.A Field experiment on four sorghum genotypes was conducted to study the influence of dates of sowing on seed yield and quality traits in rabi sorghum during 2016-17 at the Main Agricultural Research Station (MARS), University of Agricultural Sciences, Dharwad. The experiment consisted of six sowing dates and four genotypes assigned to sub plots in a split plot design with three replications. The phenological results indicated that, the days to 50 per cent flowering, complete flowering and pollen fertility per cent was more under 44th SMW (Standard Meteorological Week) in the genotype BJV-44 (83.33 days, 89.19 days and 90.18 %, respectively). However, the pollen germination per cent was found significantly maximum under 39th SMW in the genotype M 35-1 (63.85 %) and the least was recorded by RS-585 (35.56 %) under 44th SMW sowing. Further, the yield and yield associated traits decreased with delayed sowing. Significantly higher number of seeds per panicle, seed weight per ear head, seed set per cent, test weight and seed yield was higher under 39th SMW in the genotype BJV-44 (1,403, 69.80 g, 81.13 %, 45.81 g and 1,508 kg ha-1, respectively). The influence of dates of sowing resulted in reduced test weight and seed yield under delayed sowing conditions. Similarly, seed germination, root length, seedling dry weight and seedling vigour index were found significantly higher under 39th SMW in genotype BJV-44 (94.94 %. 15.52 cm, 3535 and 16.23 mg, respectively). However, the shoot length was maximum under 37th SMW in genotype BJV-44 (23.23 cm). The quality parameters of the genotypes were reduced with delay in sowing dates. The results indicated that, genotype BJV-44 was found to be thermo insensitive and higher reproductive efficiency as compared to other genotypes. Thus, it may provide better source for breeding heat tolerant genotypes in rabi sorghum.ThesisItem Open Access Effect of Date of Sowing and Foliar Application of Salicylic Acid on Seed Yield and Quality of Groundnut (Arachis hypogaea L.) In cv. G2-52(University of Agricultural Science, Dharwad, 2017-07) Subhash G.S.; Uppar, D.S.A field experiment was conducted at the Main Agricultural Research Station (MARS), University of Agricultural Sciences, Dharwad during kharif, 2016 to assess the effect of date of sowing and foliar application of salicylic acid on seed yield and quality of groundnut (Arachis hypogaea L.) in cv. G2-52. The field experiment consisted of four dates of sowing [June 15th (D1), July 7th (D2), August 1st (D3) and August 21st (D4)] and four different dosages [0 (S1), 50 (S2), 100 (S3) and 150 (S4) ppm] of salicylic acid was laid out in split plot design with three replications. Among all the dates, significantly higher plant height and leaf area were recorded under D1 and D2 dates of sowing. The phenological parameters like days to 50 per cent flowering, days to pod initiation and days to physiological maturity took significantly more number of days with optimum growing degree days, heat use efficiency, total dry matter production and its distribution, chlorophyll content and relative water content for June 15th sowing. Yield and yield attributes like, number of pods per plant (30.02), number of seeds per plant (44.03), shelling per cent (73.92), 100 seed weight (39.79 g), yield per plant (17.51 g), haulm yield (4.74 q/ha), pod yield (4.62 kg plot-1) and pod yield (3,852 kg ha-1) was significantly maximum under D1 date of sowing. Seed quality parameters like germination per cent, root length, shoot length, seedling vigour index and seedling dry weight were also showed significantly maximum in D1 (June 15th) date of sowing. Significantly higher morpho-physiological parameters, yield and yield components were recorded in S3 (100 ppm), followed by S2, S1 and S4. The similar trend was observed in seed quality parameters. Thus the application of 100 ppm of salicylic acid was optimum to increase the groundnut productivity under D1 date of sowing.
