图3 应用5套NIL-F 2 群体对千粒重的QTL检测结果 TGW: 千粒重; A : 加性效应, 指密阳46等位基因取代珍汕97等位基因所产生的遗传效应; D : 显性效应; D [ A ]: 显性度; br R 2 : QTL效应对表型方差的贡献率。
Fig. 3 QTL analysis for 1000-grain weight using five NIL-F 2 populations TGW: 1000-grain weight; A : additive effect measured as the genetic effect when a Zhenshan 97 allele is replaced by a Milyang 46 allele; D : dominance effect; D [ A ]: degree of dominance; R 2 : proportion of phenotypic variance explained by the QTL effect.
