Fig. 2From: Genetic basis of heterosis for yield and yield components explored by QTL mapping across four genetic populations in upland cottonPhenotypic variance explained by the m-QTL and e-QTL effects for yield and yield components. a Phenotypic variance explained by the m-QTLs. PV: the phenotypic variance that the total effects explained; PV (A): the phenotypic variation that the main effect explained; PV (AE): the phenotypic variation that the environmental interaction effect explained. b Phenotypic variance explained by the e-QTLs. PV: the phenotypic variation that the total epistasis effect explained; PV (AA): the phenotypic variation that the main epistasis effect explained; PV (AAE): the phenotypic variation that the environmental interaction of the epistasis effect explained. P1: RILs; P2: IF2s; P3: HSBCF1s; P4: MARBCF1s; P5: IF2MPHs; P6: HSBCF1MPHs; P7: MARBCF1MPHsBack to article page
