摘　　要：Many excellent genes in wild rice have been lost during the domestication of wild rice to cultivated rice.In this study,introgression lines(ILs)were produced with a wild rice(Oryza rufipogon)accession,BJ194,as a donor parent and an indica restorer line,Zhonghui 8015(ZH8015),as a recipient parent to map QTLs for plant height.We identified four QTLs(qPH3.1,qPH3.2,qPH2,and qPH8)related to plant height distributed on chromosomes 2,3 and 8.Furthermore,we sequenced and analyzed qPH3.2 located in the interval of RM15753-RM3525,and found this QTL may be a new locus regulating rice plant height.
