In the present regime of Intellectual Property Rights, the distinctness of a candidate variety from all other varieties is an important criterion for granting protection of Plant Breeder's Right. Keeping this in view, a total of 29 released Indian cultivars of lentil was grouped for several agro-morphological descriptors. Most of the varieties belonged to medium and large seededcategory.Verylarge seedsize wasobservedin‘IPL 406’ and ‘PL 5’. Varieties were also classified on the basis of presence or absence of stem pigmentation. It was present in all thevarietiesexcept in‘DPL15’, ‘DPL62’,‘IPL81’, ‘L4076’,‘LH 84-8’, ‘K 75’, ‘NDL 1’, ‘PL 77–12’ and ‘IPL406’. The lentil varieties were largely of medium to late flowering category except ‘Asha’, ‘Ranjan’, ‘Subrita’, ‘JL1’, ‘JL3’ and ‘LH84-8’ which belonged to early flowering category. Considerable variability was observed for leaflet size. Varieties with small leaflet size were ‘VL1’, ‘VL103’, ‘PL639’, ‘PL4’, ‘L4147’, ‘Asha’, ‘JL1’, ‘Subrita’, ‘LL699’ and ‘VL126’. Other varieties were of medium size leaflet except ‘IPL81’, ‘PL5’, ‘L4076’, ‘K75’ and ‘PL77–12’ where large sized leaflet was present. Seed testa colour was brown in all the varieties except ‘VL1’ and ‘VL4’ which had black testa colour. Such characterization of released cultivars may provide valuable information for the strengthening of lentil breeding programme.
