Abstract:
An experiment was conducted during the period from November 2015 to April 2016 in rabi
season in the experimental area of Sher-e-Bangla Agricultural University, Sher-e-Bangla
Nagar, Dhaka to find out the variability and interrelationship of yield and yield contributing
traits in Bt Brinjal (Solanum melongena L.) along with parents. The result indicated that
different 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 advanced in percent of mean were
observed for all the traits of different brinjal genotypes indicated additive gene effects of
these traits. Fruit diameter 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. Regarding fruit diameter
and yield per plant, the genotype BARI Bt Begun 4 performed best. BARI Bt Begun 3 and
BARI Bt Begun 2 produce higher yield next to the genotype BARI Bt Begun 4. Based on
the comparison of eight brinjal varieties, BARI Bt Begun 4 was found to be the highest
yielder followed by BARI Bt Begun 3 and BARI Bt Begun 2. The other varieties showed
much less yield compared to the formers. As no insecticide was used to study the resistance
capacity of the brinjal genotypes against Lepidopteran insects like fruit and shoot borer, all
Bt Brinjal varieties showed much higher yields compared to their non Bt Brinjal parents.
