Seed Health Evaluation of Different Varieties of Lentil by Physical Methods

Abstract

Seed health evaluation was attempted for seed lots of different varieties of lentil viz. DPL-62, IPL-81, JL-3, K-75, L-4076 and local variety from randomly selected village. Dry seed examination showed the status of healthy seeds, damaged seeds, shrunken seeds, small or under sized seeds, discoloured seeds, inert matter and other crop variety seeds in seed lots. Dry seed examination revealed that JL-3 variety showed the maximum purity as compare to other lentil varieties taken in the study and local variety were found as minimum pure among all the varieties. Washing test was also performed and maximum spore load was recorded from seed lot of local variety which include i.e. 20×10² which includes eight spores of Rhizopus stolonifer, three spores of Aspergillus flavus, two spores each of Aspergillus niger, Chaetomium globosum, Trichoderma viride and Cladosporium sp. and one spore of Alternaria alternata. While JL-3 and K-75 (13×10²) variety showed the minimum spore load among all the lentil varieties taken in the study.
