Abstract:

Seed dormancy is an important trait affecting grain yield and quality in cereal crops. It is controlled by its own complicated genetic and environmental factors. The polymorphism pattern study of 24 rice genotypes for RM primers used in the present molecular study were clearly classified the rice genotypes into dormant (Cluster I, Cluster IIA) and non-dormant (Cluster II B, Cluster III). In the present study, a total of 40 alleles were detected across the 24 rice genotypes by 11 polymorphic SSR markers. The number of alleles generated per locus by each marker ranged from 2 to 6. Maximum number of alleles (6) produced by RM 520. The PIC values among the SSR loci tested are ranged from 0.1411 (RM 480) to 0.7025 (RM 520) with an average of 0.495 per locus. Among the polymorphic SSR markers detected, RM 520 showed maximum numbers of alleles (6) as well as the highest PIC value (0.709). The markers showed average PIC value of 0.4954 that almost showed 49 % polymorphism, which confirms that SSR markers used in this study were highly informative for genetic studies and are extremely useful in distinguishing the polymorphic rate of a marker at a specific locus.
