Identification of elite lines for synchronous pods maturity through screening of local and exotic mungbean [Vigna radiata (L.) Wilczek] genotypes

Indeterminate plant growth and non- synchronous maturation of pods are the major obstacles towards harvesting of mungbean crop in one sitting. in order to identify elite mungbean genotypes for synchronous pods maturity and plant growth related traits,a principal component analysis was used. fifty local and exotic mungbean genotypes were used for the purpose. the first four pcs with eigen value >1 contributed 99.77% of the variability among the genotypes. the contribution of pc 1 towards total divergence was 53.47%. the studied traits contributed negatively to pc 1 except seed yield per plant. days to 90% pods maturity and plant height at 90% pods maturity contributed significantly negatively towards the mentioned component. therefore pc 1 could be attributed to plant maturity related traits. plant height at first flower initiation has a positive weight on pc 2 while days to first pod maturity has a significant negative influence on it. the said pc is more related to plant flowering traits. cluster analysis and class profile studies revealed the distinctiveness of variety azri-2006 and nm-2006. the said varieties showed lower estimates for most of the studied traits while the genotype 97006 and aum- 9 have demonstrated the contrasting features especially for degree of indetermination of pod maturity and plant height. © 2015,university of agriculture. all rights reserved.
