Abstract:
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 (Tuni local × EC-169089) 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.
In the cross (Tuni local x EC-169089) the per cent genetic gain from F4 to F5 and F5 to F6 generation for the yield contributing characters were; yield per plant (23.44 and 11.86), plant height (3.26 and 4.38), number of primarybranches (4.78 and 1.52), number of fruits per inflorescence (3.89 and 6.66), fruit length (10.21 and 9.27), fruit girth (1.73 and 11.21), number of fruits per plant (16.26 and 0.67), average fruit weight (6.78 and 11.36), fruit firmness (2.96 and 0.41) and phenols (-0.63 and -7.96) respectively. Four promising plants were selected in F6 generation and selfed for further preliminary yield trials.
