Abstract:
An experiment was conducted to study genetic variability, character association and
path coefficient analysis for yield and its contributing traits in Brinjal genotypes. The
experiment was carried out at the Ilorticulture farm of Shre-E Bangla Agriculture
University. Shre-E Bangla Nagar Dhaka-1207. The results indicated that diiTeren
brinjal genotypes differed significantly regarding all the characters studied.
Minimum differences of genotypic and phenotypic variances and coefficient of
variation as well as high heritability coupled with high genetic advance and genetic
advanced in percent of mean were observed for all the traits of different brinjat
genotypes indicated additive gene effects of these traits. Number of fruit per plant
and single fruit weight of different brinjal genotypes had a high degree of significant
positive association with yield per plant and high positive direct effect indicated that
these characters had the major contribution towards the yield per plant. Selection
could be made based on these two traits for the improvement of yield of briqjal
genotypes. Regarding singal fruit weight and yield per plant. the genotype Line-Ol x
Line-25F2 perthrmed best. Genotypes Line-Ol x Line-25F1, I,ine-23x Line-24F2
produced higher yields next to genotype l,ine-Olx Line-251'- 2. In respect of days to
flowering and days to first harvest Line_23x Linc-24F'2 was Ibund as the earliest
genotype.
