A doubled haploid population of 123 lines from IR64/Azucena was used to dissect the developmental behavior and genotype by environment interaction for plant height by conditional and unconditional quantitative trait loci (QTL) mapping methods in rice. It was shown that the number of QTL detected was different at various measuring stages. Some QTL could be detected at all stages and some only at one or several stages. More QTL could be found on the basis of time-dependent measures of different stages. By conditional QTL mapping of time-dependent measures, it is possible to reveal dynamic gene expression for quantitative traits. Mapping QTL for genetic main effects and GE interaction effects could help us in understanding the nature of QTL x environment interaction for the development of quantitative traits.
利用由IR64/阿苏辛娜构建的包含123个株系的加倍单倍体群体，通过水稻株高的条件和非条件数量性状位点（QTL）定位方法，剖析发育行为以及基因型与环境的互作。结果表明，在不同测量阶段检测到的QTL数量不同。一些QTL在所有阶段都能检测到，而有些仅在一个或几个阶段能检测到。基于不同阶段的时间依赖性测量可以发现更多的QTL。通过对时间依赖性测量进行条件QTL定位，有可能揭示数量性状的动态基因表达。对遗传主效应和基因型与环境互作效应进行QTL定位，有助于我们理解数量性状发育过程中QTL与环境互作的本质。
