| 摘 要： | 应用珍汕97B／密阳46的F2和重组自交系（RIL）群体，建立RFLP连锁图，检测控制稻谷产量及其5个构成因子的QTL。结果表明，具有较大加性效应者，能同时在F2和RIL群体中检测到。而且，在重组自交系群体中，发现设重复的表型鉴定与基于单株的表型鉴定，对效应较高的QTL的检测影响不大。 |

| Abstract: | In the F2 and recombinant inbred populations of Zhenshan 97B/Milyang 46, RFLP linkage maps were constructed to detect QTL for yield and its component traits. Results indicated that QTL having substantial additive effects were generally detected in both F2 and recombinant inbred populations. In addition, the trait performances were measured either based on a single plant or on replicated trials in the recombinant inbred population hardly affected the detection of QTL of higher effects. |
| Keywords: | quantitative trait loci (QTL) additive effect RFLP rice |
