Seed health evaluation was attempted for seed lots of different pea varieties viz., IPFD 10-12, Paras, Indira matar, KPMR 400, Shubhra, Ambika and local variety from randomly selected village by physical methods. In dry seed examination, seed lots of different pea varieties showed distinct variation in healthy seeds, damaged, discoloured, small/undersized, shrunken seeds, weed seeds and inert matters. Dry seed examination revealed that IPFD 10-12 variety showed highest purity where as local variety were recorded as least pure as compared to other pea varieties taken in the study. In washing test, maximum spore load was recorded from seed lot of local variety which include six spores of Aspergillus flavus, four spores of Aspergillus niger, two spores of Aspergillus fumigatus, one spore of Trichoderma sp, one spore of Alternaria sp, sevens pores of Rhizopus sp., one hyphal fragment of Rhizoctonia sp. and two spores of Fusarium sp. while Shubhra variety showed the minimum spore load among all the pea varieties taken in the study.
