Seeds of grasspea contain an unusual amino acid, B-(N)-Oxalyl-amino-L-alanine (BOAA) which is responsible for an incurable paralysis of the lower limbs of men, called lathyrism. This study included sixteen local and seven exotic cultivars of grasspea to ascertain the variability and the relationship existing among seed size and content of protein and BOAA in the seeds. Weight of 1000 seeds varied from 40-67 gm and the exotic germplasm had comparatively bigger seeds than the local cultivars. The protein and BOAA percent ranged from 24.54 to 34.05 and 0.22 to 2.08, respectively. A significant positive correlation was obtained only between seed size and protein content (0.775) but negative associat1427ion was obtained between seed size and BOAA. There was no association between the content of protein and BOAA. Therefore, it may be feasible to develop low neurotoxin varieties by selecting for bold seed size following hybridization of bold seeded and low neurotoxin types with those having small seeds and high neuroto
