There is a strong relationship between the consumption of grasspea (Lathyrus sativus L.) and “lathyrism” disease caused by a neurotoxin, β-N-oxalyl-L-a,β-diaminopropionoc acid called ODAP or BOAA. The objective of this study was to compare α, β and total ODAP found in grasspea genotypes sown in winter and spring seasons during 2007/08 and grown under rainy conditions in semi-arid regions of Turkey. Biochemical compounds of α, β and total ODAP were found to be higher in spring-sown grass peas than those of winter-sown ones. Grasspea 452, 508 and 519 genotypes had lower β-ODAP levels in winter- and spring-sown.
