Abstract

Using an F₂ as the mapping population derived from indica Zhaiyeqing 8 and japonica Jingxi 17 of rice, a linkage map was constructed, which consisted of 54 restriction fragment length polymorphism (RFLP) markers. By using the interval mapping procedure based on 2 flanking markers, 11 quantitative trait loci (QTLs) were mapped for 4 traits: days to heading (Dth1), tiller angle (Ta1), spikelet number per panicle (Sn1, Sn2, Sn3) and spikelet density (Sdn1-Sdn6). An example was taken for QTL mapping of rice, and the interval mapping was shown to be able to detect the QTL located between 2 flanking markers. For a specific trait, more than one QTL could be found on one chromosome. Genetically related traits could be controlled by the same group of QTLs or polygenic system.
