The present investigation entitled “Genetic studies in advanced generations for yield and yield contributing traits in brinjal (Solanum melongena L.)” was conducted at College of Horticulture, Venkataramannagudem, Andhra Pradesh during Kharif-2020, Rabi-2020 and Kharif-2021. The F4, F5 and F6 generations of the cross (EC-169089 × Pennada) were evaluated with the objective of selecting superior genotypes through pedigree method of selection for economically important traits and to assess the various genetic parameters for the brinjal crop improvement. The data from advanced generations were collected and statistically analyzed to compute mean, range, phenotypic and genotypic coefficients of variance, heritability, expected genetic advance, genetic advance as per cent mean, genetic gain.

The pedigree of the cross (EC-169089 × Pennada) recorded the genetic gain from F₄ to F₅ and F₅ to F₆ generation; yield per plant (34.43 and 5.17), number of primary branches (7.90 and 4.34), plant spread N-S (12.84 and 0.82), plant spread E-W (15.36 and 2.14), number of fruits per inflorescence (10.08 and 0.39), fruit length (9.65 and 7.94), number of fruits per plant (20.16 and 10.88),fruit volume (4.98 and 2.31), average fruit weight (5.53 and 7.83), fruit firmness (5.08 and 32.66) respectively. Two promising plants were selected in F6 generation and selfed for further preliminary yield trials.
