Abstract
Expressed sequence tag (ESTs)-derived microsatellite markers were developed in Lathyrus sativus by screening the National Center for Biotechnology Information (NCBI) database. The usefulness of these novel markers was validated for size polymorphism among grasspea accessions. • Three hundred EST-simple sequence repeat (SSR) primer pairs were identified and loci characterized for size polymorphism among 24 grasspea accessions from worldwide sources. Among them 139 SSR loci produced no PCR product, 117 SSR loci were monomorphic, and 44 SSR loci were polymorphic. The mean number of alleles per locus ranged from two to 11. The observed heterozygosity and expected heterozygosity ranged from 0.000 to 1.000 and 0.042 to 0.836, respectively. • These novel markers will be useful and convenient to study genetic mapping and molecular breeding in grasspea.
