Cumulative genetic effects (A) and phenotypic variations (B) explained by different genetic components for stem WSC accumulation and remobilization in the wheat RIL population. The stem WSC-related traits evaluated herein are involved in grain weight of main spike (GWMS); water-soluble carbohydrate (WSC) concentration at the anthesis stage (WSCf), the grain-filling stage (WSCg) and the maturity stage (WSCm); WSC remobilization rate at the pre-anthesis (WRRpr) and the post-anthesis (WRRps); WSC remobilization rate at the pre-anthesis (WCRpr) and the post-anthesis (WCRps). a, aa, ae and aae represent additive effect, epistatic effect, and environmental interaction effect by additive (ae) and epistatic QTLs (aae), respectively
