*P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.005.
Estimates of additive (VA) and dominance (VD) variance, average degree of dominance (a.d.d.), and tests for additive × additive ([aa]) and additive × dominance and dominance × dominance ([aa], [dd]) epistasis.
VA was highly significant (P ≤ 0.005) for all traits; VD was highly significant for all traits, except TP (significant at P ≤ 0.05) in the II hybrid.
