Abstract:
Study on genetic diversity based on qualitative and quantitative character among 15
genotypes of brinjal were done on 15 brinjal genotypes at the farm of Sher-e- Bangla
Agricultural University, Dhaka during November, 2013 to April, 2014 .Diversity was
estimated by cluster distance. Significant variations were observed among the brinjal
genotypes for all the parameters under study. Multivariate techniques were used to
classify the genotypes. All the genotypes were grouped into five clusters. Principal
Component Analysis, Principal Coordinate Analysis and Canonical Variate Analysis
had exhibited similar results. Cluster I had the maximum of saven and the cluster III
and IV had the minimum of 1 genotype respectively. The highest intra-cluster distance
was observed in cluster II followed by I. The highest inter-cluster distance was
observed between cluster III and IV and the lowest between the cluster I and II. The
characters such as number of fruits per plant, fruit length, fruit diameter and fruit
weight contributed maximum towards divergence among the genotypes. Genetic
divergence was not found to be related to geographical diversity. Analyzing diversity
pattern and other agronomic performance, the genotype 6 from cluster II, genotype 13
from cluster IV, genotype 14 from cluster I and 15 from cluster V were selected as
better parents for future hybridization program.
