Description Grass pea (Lathyrus sativus L.) is considered as one of the hardiest crops for
adaptation to climate change, combining drought tolerance with waterlogging tolerance.
It is a highly valued crop for human food and animal feed and fodder, because of its
protein-rich seeds (>30%) and leaves (~17% protein). However, this crop remains
underutilized and neglected because of the poorly characterized genetic resources.
Here, we characterized 101 accessions of cultivated species along with 17 wild
species, each represented by one accession, with 18 EST-SSR markers. A total of 67
alleles were detected with an average of 3.72 alleles per locus and polymorphism
information content (PIC) of 0.515. The STRUCTURE analysis indicated evidence for
the presence of significant population structure in grass pea. The entire population
identified four genetically distinct groups or admixtures within the L. sativus and wild
species. Group I consisted of 34 accessions including the accession of L. cicera, which
showed low ?-N-Oxalyl-L-?, ?-diamino propionic acid (?-ODAP) content. Group II was
represented by 19 accessions, which included the remaining 16 wild species along with
three cultivated accessions, local landrace, Bang-9 and Bang-11. Group III had 36
accessions of cultivated species with high ?-ODAP germplasm, while Group IV
consisted of 29 accessions of cultivated species, which had high ?-ODAP content
under heat and drought stress.
