Abstract: The experiment on thirty five genotypes of Indian mustard (Brassica juncea L. Czern & Coss) was carried out during 2014-2015 in Completely Randomized Design (CRD) with three replications at Seed Testing Laboratory (STL) of Seed Technology Section, Narendra Deva University of Agriculture & Technology, Kumarganj, Faizabad (U.P.) India, in germinator for germination as per ISTA method to evaluate ten seed vigour traits viz. 1000-seed weight (g), field emergence (%), speed of germination (at field), germination, speed of germination, root length (cm), shoot length (cm), seedling length (cm), seedling dry weight (mg) and vigour index. Standard statistical techniques such as correlation between different characters Searle (1961) and Path coefficient analysis by Dewey and Lu (1959) were analysed, in which vigour index was kept as dependant character. Highly significant differences were observed among the genotypes for all the seed vigour traits. A very strong highly significance and positive correlation of vigour index at genotypic and phenotypic level were observed with root length, shoot length, seedling length and seedling dry weight. Path coefficient analysis carried out at genotypic as well as phenotypic level, identified root length, shoot length and germination percentage as major direct contributors towards, vigour index. Root length, seedling length, seedling length and germination emerged as most important indirect contributors to vigour index. The characters identified above as important direct and indirect components in vigour index merit due consideration in formulating effective selection strategy in Indian mustard for improving overall seed quality.
