Screening and Identification of SSR Markers for Genetic Diversity for Mungbean [Vigna radiata (L.) Wilczek]

Mungbean (Vigna radiata) is an economically important pulse crop and is an excellent source of easily digestible proteins with low flatulence which complements the staple rice diet in Asia and particularly in India. Information about mungbean germplasm diversity and genetic relationships among accessions or cultivars is of fundamental importance for breeding and the management of germplasm. To study genetic diversity at molecular level different types of DNA markers can be used. Among the different DNA markers, simple sequence repeat (SSR) markers are highly variable in the genome, also reproducible and cost effective. A total of ten SSR primers that showed stable amplification was used to explore the diversity in six mungbean genotypes. Of these, two SSR primers VrSSR_6_ 746 and VrSSR_1_31 showed polymorphism in the six mungbean genotypes, while the remaining were monomorphic. Collectively, the results of present study can be helpful in planning the utilization patterns and management of mungbean genotypes.
