Abstract
Indian mustard has the share of over 80% to the total rapeseed-mustard production in the country. Present investigation is conducted to guesstimate the possible presence of diversity among 38 germplasm lines and 5 cultivated varieties of Indian mustard by using 12 morpho-physiological parameters as well as microsatellite markers. Phenotypic analysis of variance for 12 yield and its attributing traits revealed that, the genotypes taken for this investigation had significant amount of genetic variation. Variances due to genotypes were highly significant for all the characters except numbers of primary branches per plant, siliqua length, numbers of seeds/siliqua and 1000-seed weight. In our study, a total of eleven polymorphic SSR molecular markers were used and showed sufficiently high sensitivity to detect DNA polymorphisms. Information generated from the current study would be helpful in the improvement of Indian mustard by the means of conventional and/or molecular breeding in impending days.
