Abstract:
A total of ten genotypes of soybean were evaluated in the laboratory of the Department of Genetics and Plant Breeding, School of Agricultural Research and Rural Development, Nagaland University, Medziphema Campus, Nagaland during the year of 2021. The experiment was carried out following a Completely Randomized Design in three replications. The analysis of variance revealed significant differences among genotypes for all the characters studied, indicating high degree of variability in the material. The high genotypic and phenotypic coefficient of variation was observed for seedling vigour index II, germination percentage, seedling vigour index vigour I and dry root weight at 20 days. In the present study, it can be concluded that characters such as seedling vigour index I, seedling vigour index II, emergence of plumule and germination percentage have high heritability estimates coupled with high genetic advance indicating the role of additive genes effects in controlling these traits and can be improved by applying phenotypic selection. Correlation studies indicated that emergence of plumule, germination percentage, shoot length at 20^th days, fresh shoot weight, dry root weight at 20^th days, dry shoot weight at 20^th days and seedling vigour index I have strong positive correlation with seedlings vigour index II at genotypic level indicating relative utility of these traits for selection.
