Genetic varibaility and correlation analysis for yield components in mungbean ( vigna radiata L. wilezek )

摘要

20 Mungbean (Vigna radiata L. Wilezek) genotypes were tested for genetic variability and correlation among different yield contributing traits i.e., plant height, pods plant ^-1 , pod length, seed pod ^-1 , biological yield, and grain yield. Maximum plant height was observed for genotype NFM5-63-19 cm; maximum number of pods plant ^-1 was recorded for genotype NFM5-63-19, while; genotype NFM-12-8 and NFM-6-5 found with a maximum pod length. Similarly the maximum number of seed pod^-1_, biological yield and grain yield was observed in genotype NFM-6-5, NFM-12-6 and NM-98 respectively. The high heritability was recorded for pod length (99%) and plant height (70%), while pods plant^-1 (29%) and seed pod ^-1 (17%) had low heritability. Based on genotypic correlation analysis characters like plant height, pods plant ^-1 , pod length and on phenotypic basis grain yield and seed pod ^-1 could be the best criteria in any breeding program for increasing yield in mungbean genotypes under agro-climatic conditions of Peshawar.
