Deskripsi
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.
