GENETIC ASSOCIATION AND PATH ANALYSIS FOR YIELD CONTRIBUTING TRAITS IN MUNGBEAN (Vigna radiata L. WILCZEK)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 52
Abstract
Genetic variability and character association in 18 advanced breeding lines (F5) with two diverse parents of mungbean for different quantitative characters were studied in kharif 2012. The analysis of variance revealed highly significant difference for all characters, under study among the genotypes, indicating the presence of sufficient amount of variability in the genotypes. Thus, there is ample scope for selection of different quantitative characters for crop improvement. The highest GCV and PCV were observed for primary branches per plant and biological yield per plant respectively. High estimates of genetic advance as percent of mean were observed for plant height and biological yield per plant. High significant positive correlation was recorded for biological yield per plant and significant negative association for 100 grain weight at both genotypic and phenotypic levels with grain yield per plant and biological yield per plant, harvest index, pods per plant, plant height, days to maturity, pod length and 100 grain weight had direct positive effect on grain yield per plant.
