a

Joint: results obtained based on combined data of the BC3F2, BC3F2:3, and BC3F2:4 generations.

b

QTL with main effect of locus i or j detected in one-way analysis.

c

Epistatic effects of the additive × additive interaction. A positive number indicates that the G. hirsutum alleles increase trait values; a negative number indicates that the G. mustelinum alleles increase trait values.

d

Phenotypic variance explained by additive × additive interaction effects.

e

Phenotypic variance explained by AA by environment effect.
