一个控制水稻株高QTL qPH3的遗传分析
Genetic Analysis of a QTL qPH3 for Plant Height in Rice
摘要
Abstract
A recombinant inbred population derived from ihe cross between a javonica(D50)and an indica( HB277)rit:e 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 RHL-F2 population was constructed. The major QTL qPH3 with the explained variance of 76. 13% was detected with the RHL-Fj 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 map-based cloning of this QTL.关键词
