A recombinant inbred population derived from the cross between a javonica（D50）and an indica（HB277）rice was used to investigate the genetic factors affecting plant height. Ａ total of six quantitative trait loci（QTLs）with significant additive effect were identified for the plant height, and they were located on chromosome 1, 2, 3, 4, 6 and 8. One QTL qPH3 can stably express and have significant additive effects in Hangzhou, Zhejiang Province with the explained variance of 16.52% and Linshui, Hainan Province with the explained variance of 16.60%. One residual heterozygous line(RHL) was selected from the RILs and a RHLF2 population was constructed. The major QTL qPH3 with the explained variance of 76.13% was detected with the RHLF2 population. By progeny tests, qPH3 was finally mapped within about 204 kb in the region RM16211-RM16237. These results will be helpful for fine mapping and mapbased cloning of this QTL.
