The experiment was conducted at the laboratories of the Department of Seed Science and Technology, CCS HAU, Hisar, during 2014-15 and 2015-16 to assess the seed vigour of twenty Indian mustard varieties/genotypes. The freshly harvested seed of all the varieties was assessed for seed vigour parameters viz., test weight (g), germination percentage, seedling length (cm), seedling dry weight (mg), vigour index-I, vigour index-II, electrical conductivity test (μS cm-1g-1), tetrazolium test percentage and dehyrdogenase activity test (OD g-1ml-1). The pooled data of both the years revealed that the highest test weight (6.01) was recorded in the variety RH0406, while the highest germination percentage (96.83), seedling length (14.98), seedling dry weight (2.54), vigour index-I (1450), vigour index-II (245), tetrazolium test percentage (97.91) and dehydrogenase activity (0.847) was recorded in the variety RH30 followed by Kranti and Varuna. The lowest electrical conductivity was also recorded in the variety RH30 (12.567) followed by Kranti (13.500), Varuna (13.567) and NRCDR601 (13.822). Among all the twenty Indian mustard varieties, the varieties RH30, Kranti, Varuna and NRCDR601 showed superiority for almost all viability and vigour parameters.
