Generation mean analysis for seed yield and it’s contributing quantitative traits in chickpea (Cicer arietinum L.)

Abstract

The present investigation was conducted in rabi seasons during 2015-16, 2016-17 and 2017-18 at G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand with the objectives to study gene effects for ten yield and yield attributing traits. The experimental material consisted of three families (GL 10006 X DCP 92-3, DKG 876 X H 208 & GL 10006 X H 208) developed from four parents, each family comprised of six generations as P1, P2, F1, F2, BC1 and BC2. Scaling test, three parameter model, six parameter model and joint scaling test were used for gene action studies. Predominant and significant role of non-additive gene action i.e. dominance (h) and dominance × dominance (l) components which are non-fixable. Duplicate type of epistasis was prevalent than complementary epistasis in almost all the crosses in different traits.
