Abstract

The seeds of twelve Lathyrus species were analyzed for crude protein, ODAP, ash, mineral contents and thousand seed weight. CP content varied from 20.78% in L. cicera to 30.92% in L. ochrus. ODAP content was the most variable trait (CV= 97.81%), being highest (10.31 mg g(-1)) in L. clymenum (cultivar) and lowest (0.65 mg g(-1)) in L. laxiflorus (wild). This was followed by thousand seed weight (TSW) being highest in L. sativus (114.54 g) and lowest in L. nissolia (3.45 g). These species also exhibited a reasonable variation regarding mineral contents, especially for Ca (CV= 40.29%) and Mn (CV= 40.96%). Correlation analysis, based on interspecies means indicated that ODAP was highly correlated with TSW (r = 0.762), Zinc (r= 0.732) and B (r=- 0.507), while there was no significant correlation of ODAP with CP and ash contents.
