Mean performance and genetic variability parameters were estimated in 7 parents and twenty one hybrids of brinjal derived
from seven diallel cross combinations to identify suitable parents and F1s for brinjal cultivation.. The study revealed that highly
significant differences were observed for most of the traits. Mean performance showed that IBWL recorded highest fruit yield of
1004 g per plant followed by PPC (974g), GL (931g), MK (918g) and PPR (872g) whereas, in F1, PPC x PPR registered a fruit
yield of 1347 g per plant followed by WBPF x PPR (1317 g), IBWL x PPR (1293g), IBWL x PPC, PPL x PPR (1287g), WBPF
x PPC (1282g), IBWL x WBPF and PPL x PPC (1274g). The moderate estimates of Genotypic coefficient of variation (GCV)
and Phenotypic coefficient of variation (PCV) were observed for number of fruits per cluster, average fruit weight, total number
of fruits per plant, fruit length. Maximum Genotypic coefficient of variation (GCV) & Phenotypic coefficient of variation (PCV)
were observed for number of flowers per inflorescence, number of fruits per picking and fruit girth, indicating that selection can
be predicted to improve the brinjal genotypes for these characters. The highest estimates of heritability coupled with high genetic
advance estimated for the average fruit weight and number of fruits per plant showed effectiveness of simple selection for
improvement of these characters.
