PHYSIO-MORPHOLOGICAL CHARACTERIZATION GENETIC VARIABILITY AND CORRELATION STUDIES IN BRINJAL GENOTYPES

Abstract

Thirty five genotypes of Brinjal were studied in the experimental field of Bangladesh Agricultural Research Institute, Gazipur, during the period from September 2010 to February 2011. There was significant variation for all the characters within genotypes. The phenotypic coefficient of variation 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 no. of branches/plant, cluster II for fruit length, cluster III for no. of fruit/plant, 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.
