The present investigation was conducted at Seed Testing Laboratory of Seed Technology Section, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.). The study was based on the germplasm evaluation of 45 germplasm including three checks viz., NDR-2065, BPT 5204 and Sambha sub1. Seedling length (0.366), speed of germination (0.132), Seed width (0.108), shoot length (0.082), seed weight (0.064), root length (0.061), vigour index-II (0.057) and L/B ratio (0.033) existed substantial positive effects on vigour index-I. Seeds weight (0.875), followed by seed width (0.610), exerted very high order positive indirect effects on vigour index-I seed weight substantial positive indirect effects on seed vigour index-I via seed width were also contributed by seed width (0.610), seedling length (0.552), L/B ratio (0.294), seedling dry weight (0.037) made considerable positive indirect on vigour index-I. The lowest and highest mean performance for root length (cm) was noted for B-4311 (10.50 cm) and HRT-m-20/3220 (31.20 cm) respectively. None of the 45 lines were statically inferior or superior than general mean for root length which 14.63 cm. out of 45 genotypes, nineteen were statistically at par with the best genotype is HRT-m-20/3220.
