A total of twenty-five grass pea (Lathyrus sativus L.) genotypes of released varieties, advanced lines, mutants and local collections were explored in this study. These genotypes were cultivated for two succeeding years in three different locations namely red lateritic zone (Shekhampur), gangetic alluvial zone (Kalyani) and saline zone of Sundarban region of west Bengal (Kakdwip) to evaluate the performance on the basis of yield and quality traits. The stability of the genotypes was established by AMMI and Biplot analysis. It was found that the neurotoxin content of grass pea, β-L-oxalyl-2,3diaminopropionic acid (β-ODAP), did not show any difference under various environmental conditions and the gangetic alluvial zone was proved to be the ideal test location for grass pea genotypes. The BK-37-2 advanced line was found to be the most stable genotype in respect of yield under all the tested environments and can be used in future breeding programmes.
