Co-Heritability of Maturity and Yield Associated Traits In Mungbean (Vigna radiata. L.)

Abstract

Mungbean is an imperative pulse crop of many Asian countries including Pakistan. The importance of mungbean is increasing throughout the world. So, current experiment was planned to estimate variability, co-heritability for maturity and yield components of 24 mungbean genotypes during crop period 2015, at “The University of Agriculture”, Peshawar in a randomized complete block design with thrice replications. Data were noted on maturity interval, plant height, pods plant^-1, 1000-seed weight, and seed yield”. The scrutiny of variance exhibited substantial variations among mungbean genotypes for all parameters. Means for maturity, plant height, pods plant^-1, 1000-seed weight, and seed yield ranged from 87.33-120.33 days, 86.67-132.73 cm, 50.36-79.16, 50.74-81.48g, and 1007.41-1986.48 kg ha^-1, respectively. Genetic variances for most of characters were superior as compared to environmental variances. Moderate heritability was documented for plant height, pods plant ^-1 while high broad sense heritability was observed for maturity, 1000-seed weight and seed yield. High co-heritability ranged of (0.63-0.99) recoded for all pairs except pods plant^-1.Thus mungbean yield can be enhanced by selecting yield component traits expressing positive co-heritability with each other as well as seed yield.
