  1. “–” indicates no significant QTL in the according substitution segment of DSSL. P < 0.05 indicates additive effects of QTL or epistatic effects between QTLs existed in substitution segments of DSSL; while P > 0.05 indicates no additive effects of QTL or no epistatic effects between QTLs existed in substitution segments of DSSL
