Genotyping of Low β-ODAP Grass Pea (Lathyrus sativus L.) Germplasm with EST-SSR Markers

Abstract

Grass pea (Lathyrus sativus L.) is an important protein source in arid regions as both human and animal food. Despite its significance, the use of grass pea is limited by the presence of β-N-oxalyl-L-a,bdiaminopropionic acid (β-ODAP) which can cause neurological disorders. Breeding studies in grass pea have therefore focused on developing high-yielding varieties with low β-ODAP content. However, the narrow range of genetic diversity and the restricted genomic tools in grass pea have slowed progress in such bre…
