Seedling vigour is an agronomical trait and sign of potential seed germination. It improves the speed, uniformity of the seedlings with good crop stand establishment and grain yield. High vigour is a characteristic of high-quality seed. Therefore the present study was undertaken to assess seedling vigour in 31 rice genotypes and revealed significant genotypic variability among the seedling vigour related traits with highest heritability (90.7%) for dry weight. High seedling vigour (3406) was expressed in Vandana followed by Bala, AUS 276, Adday sel, N22 and IR 64. High heritability coupled with high GAM was observed for shoot length (83.5 and 52.5) followed by seedling dry weight (90.7 and 45.4) mesocotyle length (80.2 and 56.5). Seedling length showed highly significant positive correlation with vigour index (0.98091), shoot length (0.67444), root length (0.58805) and dry weight (0.37001). The promising genotypes were identified for incorporation into breeding programmes. Variability and correlation estimates revealed the selection of characters for identification of high seed vigour.
