Abstract

A genetic map including 120 RFLP markers covering 1418.2 cM has been
constructed using a BC1 population derived from a cross between common wild
rice (Oryza rufipogon Griff.) from Dongxiang, Jiangxi Province, China, and an
elite Indica variety Guichao 2. The linkage orders and genetic distances of
markers in this map are consistent with the map constructed by Rice Genome
Program of Japan except the markers of short arm of Chromosome 1. The QTLs
analysis of anther length and ratio of stigma exsertion, two key traits of
classification for cultivated rice and common wild rice indicated that there
are two QTLs controlling anther length located at the region of C424-G39 of
Chromosome 2, and C2807-C1263 of Chromosome 9 respectively. It was also found
that there are two QTLs controlling ratio of stigma exsertion, and located at
the region of C2289-R1553 of Chromosome 5 and G1149-R1963 of Chromosome 8
respectively. The detected QTLs affecting the key traits of classification for
wild rice and cultivated rice will be useful for study of molecular evolution
mechanism of cultivated rice.
