Physio-Morphological Characterization Genetic Variability and Correlation Studies in Brinjal Genotypes of Bangladesh

Abstract

Thirty five genotypes of Brinjal were studied in the experimental field of Bangladesh Agricultural Research Institute, Gazipur and there was significant variation for all the characters within genotypes. The phenotypic coefficient of variation (PCV) was higher than genotypic. The PCV estimates were high for number of branches, number of fruit per plant, single fruit weight. Heritability estimates were high for single fruit weight with high genetic advance. In spite of high heritability values for most traits, the expected genetic advance as percentage of mean ranged from 19.92 to 121.51. Multivariate analysis was performed through principal component analysis (PCA), principal coordinate analysis, cluster analysis and canonical variate analysis. As per PCA, D2 and cluster analysis, the genotypes were grouped to six clusters. The highest inter-cluster distance was between cluster II and III and lowest between V and VI. Cluster VI showed the maximum intra-cluster distance and II showed the lowest. Genotypes of cluster I were suitable for number of branchesplant-1, cluster II for fruit length, cluster III for no. of fruitplant-1, cluster IV for single fruit weight and yield. Considering the performances, genotypes SM-111, SM-84, EGN-27, SM-183, BARI begun-6 might be considered as suitable parents for efficient hybridization program.
