GENE ACTION FOR YIELD AND ITS COMPONENTS IN GRASSPEA

Published on

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.
