Gene action for yield components in eggplant (solanum melongena l.)

Abstract

Abstract : A study of the attributes for yield components of 36 Frs and their nine parents in 9x9 diallel (excluding reciprocals) of eggplant showed dominant gene actions in most of the traits, where fruit number per plant and yield per plant exhibited predominant gene action. Highest heritability (67 per cent) was observed for fruit diameter. The asymmetrical distribution of the positive and negative alleles at all loci was found for most of the characters. The Vr-Wr graphs exhibited incomplete dominance effect of genes for all the characters, except plant height and branch per plant which had controlled by dominant gene completely. The graphical analysis indicated wide genetic diversity among the parents.
