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.
