Fine Mapping of qWCR4, a Rice Chalkiness QTL Affecting Yield and Quality
Rice (Oryza sativa L.) chalkiness greatly reduces the rice quality and the commercial value.In this study, qWCR4, a previously reported quantitative trait locus (QTL) of white-core rate (WCR), was confirmed by a BC5F2 segregation population and jerome brown jersey further fine mapped to a 35.26 kb region.In the qWCR4 region, LOC_Os04g50060 and LOC_
