Gene action for seed yield and its attributing traits in fieldpea (Pisum sativum L.)
Generation mean analyses were performed to estimate the nature and magnitude of gene action for yield and its component traits in six generations (P1, P2, F1, F2, B1 and B2) obtained from two crosses (GP 02/1108 x HFP 920 and GP 02/1108 x HFP 9907B). A considerable amount of variation was observed...

| description | Generation mean analyses were performed to estimate the nature and magnitude of gene action for yield and its
component traits in six generations (P1, P2, F1, F2, B1 and B2) obtained from two crosses (GP 02/1108 x HFP 920 and
GP 02/1108 x HFP 9907B). A considerable amount of variation was observed among parents and different generations.
Individual Scaling and Joint Scaling test depicted failure of additive-dominance model for all the characters except the
number of primary branches in both crosses. Six parameter model revealed a remarkable amount of fixable component
though non fixable component was on a higher side in the majority of characters in both the crosses. Sufficient fixable
component for the traits envisaged practising pedigree method. However, to exploit additive as well as non-additive
gene effects simultaneously breeding methods like a selection from delayed generations and the bi-parental mating
approach are advocated. |
