The experiment was conducted in RCBD with three replications at OFRC, UAHS, Shivamogga during kharif 2021. Out of sixty four traits studied, significant variations were observed for all qualitative and quantitative characteristics. Out of 31 land races, Ambemohari showed maximum number of productive tillers/plant (26), Jasmine obtained highest panicle length (27.90cm), Karigajavale showed maximum panicle weight (5.30 g), Rathnasagara recorded the highest number of seeds per panicle (218) and seed yield per plant (85.80 g). Seedling and plant characters are major identification and differentiating characters among cultivar. Out of 25 markers, the highest Polymorphic Information Content (PIC) value (0.49) was obtained in RM 481 and RM 25, remaining markers showed less PIC value. It was observed that the highest PIC value results were genetically diverse land races and some markers showed related land races. In respect of seed dormancy, three (Navara, Jyothi and Misebhatta) land races showed very weak, one (Raichursanna) land race weak, one (Puttabhatta) land race moderate, five (Gowrisanna, Kiruvani, Rathnasagara, Ambemohari and MTU-1001) land races strong and twenty one land races as very strong dormancy reaction signifying considerable amount of variability among the land races. Seed dormancy positively correlated with seed length, presence of awns and germination percentage.EnglishThesis
