Abstract
The present study entitled “Genetic analysis for fruit yield and component
traits in different F2 generations of brinjal (Solanum melongena L.)” was undertaken
to analyse genetic variability in brinjal and to identify the most promising segregating
progenies during kharif, 2019 at the Research Farm, Department of Vegetable Science
& Floriculture, CSK HPKV, Palampur. Bacterial wilt resistant parents viz., Res-1,
Res-2, Hisar Shyamal, Arka Nidhi and Arka Keshav along with fifteen F2 lines were
evaluated in randomized complete block design with three replications for yield and
related horticultural traits. Significant differences were revealed from analysis of
variance in the lines for all the characters studied. On the basis of overall
performance, more particularly due to marketable fruit yield per plant and bacterial
wilt resistance, KRS among the long type and HN, HK and KH among the oblong
type have been identified as superior lines which could be used in further breeding
programme. Higher range of PCV and GCV together with high heritability and high
genetic advance were obtained for fruit diameter, fruit weight, number of marketable
fruits per plant and marketable fruit yield per plant. Correlation analysis revealed that
the yield could be improved through direct selection of traits namely, fruit diameter,
fruit weight, number of marketable fruits per plant, number of primary branches per
plant, plant height and harvest duration. From path analysis, it was clear that number
of marketable fruits per plant followed by fruit weight were the major characters and
had maximum positive direct effect on yield.
