Abstract :Fifty-one landraces and one released variety ‘Gurbuz-2001’ of grass pea insert ignore into journalissuearticles values(Lathyrus sativus L.); collected from Turkey and grown in Samsun-Turkey condition were characterized by morpho-agronomic traits, protein and neurotoxic ȕ-ODAP insert ignore into journalissuearticles values(ȕ-N-oxalyl-L-Į,ȕ-diaminopropionic acid); contents in seed. High variation was observed among landraces regarding all the studied traits. ȕ-ODAP content was determined by using capillary zone electrophoresis insert ignore into journalissuearticles values(CZE); and extreme levels of ȕ-ODAP were 1.40 and 3.05 mg g-1 in among the landraces insert ignore into journalissuearticles values(average 1.96 mg g-1);. Also the correlations between traits were investigated and, the strongest positive correlations were between main stem number and leaflet length and, between seed yield per plant and pod number per plant. Seed yield significantly insert ignore into journalissuearticles values(p< 0.01); and positively correlated with most of the investigated traits. Correlations between ȕ-ODAP content and other traits were negative or no significant. In general, many of the landraces were superior than released variety ‘Gurbuz-2001’ with their seed yield, protein content and ȕ-ODAP content
