Fifteen improved, low toxin grasspea (Lathyrus sativus L.) genotypes received from the International Centre for Agricultural research in the Dry Areas (ICARDA). Aleppo, Syria and a local check were tested for two consecutive winter seasons 2004-05 and 2005-06 in the rainfed conditions of National Agriculture research Centre (NARC), Islamabad. Aim of the study was to select the best genotypes that would give high seed yield with low neurotoxin oxalyl-diamino-propionic acid (ODAP) content. Data on maturity days, plant height, biological yield, grain yield. 100-kernel weight and harvest index were collected. The genotype Set 736 significantly outperformed other genotypes for yield and it was followed by Sel 1327, Sel 1322, and Sel 1328. These genotypes are suggested to be tested at the Quaid-e-Awam Agricultural Research Institute (QAARI), Larkana for their general cultivation/yield potential.
