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. The high estimates (> 40 %) of phenotypic (PCV) and genotypic (GCV) coefficients of variation was registered in case of shoot length (PCV=18.1129 %, GCV=17.1129 %). The magnitude of heritability in broad sense varied between 0.7947 per cent in case of seedling length to 0.9567 per cent in case of vigour index-I. The high estimates of h2 (>0.8564) were noted for vigour index-I (0.9567) followed by root length (0.8845), speed of germination (0.8749), seed weight (0.8596). Vigour index-I noticed highly significant and positive correlation with shoot length (0.454), root length (0.419), seedling dry weight (0.333), germination per cent (0.319), seed weight (0.315), seedling length (0.312), seed width (0.308), root length (0.292), speed of germination (0.281) and L/B ratio (0.216).
