Genetics of BOAA (β-N-oxalyl amino alanine) content from a 5x5 full diallel cross of grasspea indicated importance of both dominant and additive gene action. Variety P 27 emerged as a good general combiner for low BOAA content. Among the crosses, P 28/P 505 exhibited negative and significant sca effect indicating non-additive gene action for low BOAA. Study of various genetic parameters revealed that more than two genes or loci with ‘recessive’ and ‘increasing’ alleles might be involved in the synthesis of BOAA in seeds and involvement of modifiers in the background genotype could not be ruled out.
