Title: Correlation and path coefficient analysis of Blackgram (Vigna mungo L.)
Abstract: Blackgram (Vigna mungo L.) has the potential of supplying a major portion of protein demand and restoring the soil health at the same time. Research on genetic variability and correlation study between yield components of the genotypes of this crop may increase the opportunity to exploit its potential which will help meet the demand of high yield and nutrition supply. Current aim is to study the correlation coefficients and path coefficients between the genotypes to establish the selection criteria which might help to develop genotypes of high yielding potential. Moreover, studying the contribution of the yield components towards yield is also the purpose of this study. The experiment was conducted at Bangladesh Agricultural University in the summer season of 2012. Ten germplasms were evaluated through 11 morphological traits. Among the morphological traits pod weight (g) 8.81%, harvest index (7.72%), number of branches plant-1 (6.18%) and 100-seed weight (g) 5.24% had shown the highest level of coefficient of variation. Grain yield plant-1 had the highest heritability (99.43) and seed pod-1 had the lowest heritability (53.10). Relationship between physiological characters and yield contributing attributes was studied through analysis of correlation. In the present study, out of 55 associations, 22 associations were positively significant and the rest 16 were negatively significant. Yield plant-1 was positively and significantly associated with pods plant-1, pod length, weight pod-1, harvest index and 100-seed weight but negatively associated with plant height, fresh weight and dry weight. The result of the present experiment indicated that number of pod plant-1, pod length and 100-seed weight were the most important characters which exhibited positively to yield plant-1. It was observed that biomass plant-1 (0.73 g) had maximum positive direct effects on yield plant-1 followed by pods plant-1 (0.37), seeds pod-1 (0.19) by path coefficient analysis. Hence, for increasing the seed yield, direct selection of genotypes based on positively correlated traits will be more fruitful.
