| Description |
The inheritance of seed weight in cowpea was examined in a field planting of the parents, reciprocal F,s, F2 s and backcrosses to both parents of a cross between TVu 1977-OD (small seeded) and ACC 70002 (large) . Seed weight was inherited quantitatively and small seed was partially domiminant to large seed size . Gene action was predominantly additive but dominance and additive x additive epistatic effects were also significant. Broad and narrow sense heritabilities were 85 .1 ± 5 .3% and 75 .4 ± 18 .6% respectively . The minimum number of loci involved in the inheritance of seed size was eight, and each gene pair contributed up to 1 .02 g increase to seed weight . The estimate of genetic advance from F 2 to F 3 generations with 5% selection intensity was 3 .58 g . |
