Abstract:
Abstract: Forty genotypes of mungbean were evaluated
to compare the genetic divergence and association among
agronomic and yield characteristics. Analysis of variance
indicated highly significant (p < 0.01) differences for all
the traits except for 1000 seed weight. The phenotypic and
genotypic coefficient of variation was the highest for grain yield
per plant, followed by pod length. High broad sense heritability
(> 60 %) along with high genetic advance was observed for
total yield per plant, pod length, number of seeds per pod and
plant height, indicating that these characteristics would be best
for phenotypic selection. A significant negative correlation
was observed between days to flowering and total yield per
plant. Positive correlations were observed between plant
height, pod length and 1000 seed weight with total yield per
plant. Multivariate analysis showed that the first three principal
components cumulatively accounted for 69.77 % of the total
variation. The present findings could be useful in selecting
superior genotypes in mungbean breeding programmes.
