Five local cultivars of rice, viz., SKAU-23, SKAU-98, SKAU-105, SKAU-341 and SKAU-382 were evaluated for seed vigour in relation to seed size and boldness. The rice cultivars were graded into four types, viz., (Grade A) partially filled and shriveled seeds, (Grade B) bold coloured seeds, (Grade C) bold discoloured seeds and (Grade D) short bold seeds. The results revealed a positive correlation between seed size and seed vigour during different laboratory conditions under standard techniques. A significant association was also observed between seed boldness and seed vigour. Short sized and bold seeds gave significantly higher values under different vigour tests and hence proved to be more vigourous
