32. Genetic variability and trait association for morphological and yield parameters of mungbean (Vigna radiata L.)
Main Article Content
Abstract
Genetic variability in existing germplasm is mandatory before commencement of a successful breeding program. To estimate genetic variability and correlations among mungbean genotypes, an experiment was conducted at The University of Agriculture, Peshawar during 2014. Fourteen mungbean genotypes were sown in RCB design with three replications. Data were recorded on days to maturity (days), plant height (cm), pod length (cm), pods plant-1(no.), grains pod-1(g), 1000 grain weight (g), biological yield (tons ha-1) and grain yield (tons ha-1). Analysis of variance showed highly significant differences (P≤0.01) among mungbean genotypes for all the studied traits. Mean value for the said traits ranged between 67-76.3, 48.7-105.7, 7.2-9.7, 15.2-22.5, 9.3-12.0, 42.6-55.6, 8.888-13.111 and 2.022-3.401 for days to maturity, plant height, pod length, pod plant-1, grains pod-1, 1000 grain weight, biological yield and grain yield, respectively. Genotype Mung NM11 performed better for yield and yield associated parameters under agro-climatic conditions of Peshawar. Significant negative phenotypic correlation for grain yield was observed with pods plant-1 (r =-0.51) whereas, significant positive correlation was observed with 1000 grain weight (r = 0.60). Based on the results of current study, genotype “Mung NM11” could be disseminated directly among growers for the commercial production of mungbean or may be included in a cultivar development program to produce transgressive segregants.
