Genetic analysis for fruit yield in brinjal Solanum melongena L

Abstract

The present investigation entitled Genetic analysis for fruit yield in brinjal newline(Solanum melongena L.) was conducted at Vegetable Research Farm, Kalyanpur, C.S. newlineAzad University of Agriculture and Technology, Kanpur-208002(U.P.) during Rabi newlineseason 2022 and 2023. The experimental material for the present investigation comprised newlineof 100 treatments (10 parents + 45 F1 s + 45 F2 s) were used for the study of variability, newlinegenetic component variance, combining ability, heterosis and inbreeding depression, newlineheritability (narrow sense), genetic advance, correlation and direct and indirect effect on newlineeleven characters viz., days to 50% flowering after transplanting, days of first fruit newlineharvest, plant height, number of primary branches per plant, number of secondary newlinebranches per plant, fruit length, average fruit weight, number of fruit per plant, fruit newlinecircumference, fruit TSS and fruit yield per plant while three characters viz., fruiting newlinehabit, fruit shape and fruit colour were studied for visual observation. newlineThe analysis of variance revealed considerable amount of variability among newlineparents, F1 s, parent vs. F1 s and parent vs. F2 s for all the characters indicating that both newlineparents and their crosses were variable for the characters under studied. newlineThe genetic component analysis revealed the both additive genetic variance ( and#770;) newlineand dominance genetic variance ( and#770;1 and and#770;2) were significant for almost all the characters newlinein both generations indicated additive and non-additive gene action governed the newlineexpression of all characters. The estimate and#770; component was found non-significant for all newlinethe characters in both F1 and F2 generation, indicated that there is negligible effect of newlineenvironment on these traits. newline
