Generation mean analysis for yield traits in okra

Abstract

Generation mean analysis involving six generations (P1, P2, F1, F2, B1 and B2) was carried out to study the nature and magnitude of gene effects for yield and yield attributing traits. The studies were undertaken on Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University Varanasi during the year 2006 & 2007. The analysis showed the presence of additive, dominance gene effects and epistatic interactions in almost all the cases indicating the importance of both additive and non-additive gene actions in the expression of the characters. For majority of characters, duplicate type of gene action was observed. Biparental mating which could exploit both additive and non-additive type of gene effects was suggested for the improvements of the traits in the crosses studied.
