GENE ACTION FOR YIELD AND ITS COMPONENTS IN GRASSPEA

Abstract

Gene action for yield and its components was studied in three crosses of grasspea using generation mean analysis. Both additive and non-additive gene effects were involved in the expression of number of primary branches, pods per plant and grain yield per plant. Plant height was found to be predominantly under the control of dominance gene effect. Simultaneous utilization of both additive and non-additive genetic effects can be achieved by intermating of segregants in early segregating generation.
