利用352个探针分析了日本品种农林20和云南品种冲腿之间的限制性片段长度多态性(RFLP)，从中筛选出157个在农林20和冲腿间显示多态性的探针，其中55个被用于其杂交后代(农林20/冲腿)的70个F3系统的孕穗期耐冷性数量性状位点(QTL)分析。结果初步显示出一些与水稻孕穗期耐冷性有关的QTL，它们主要分布在第1、3、4、5、6、7、8、10和第12染色体上。可能在第3和第7染色体上具有对孕穗期耐冷性作用较大的QTL。

The restriction fragment length polymorphism (RFLP) between Japanese variety (Norin 20) and Yunnan variety (Chongtui) were analyzed with 352 markers in this study.One hundred and fifty-seven markers had polymorphous bands between the two varieties were detected.Fifty-five selected RFLP markers were used for the quantitative trait loci (QTL)analysis of the cold tolerance at booting stage of 70 F3 lines of the cross of Norin 20/Chongtui.The results showed that some loci are related to the cold tolerance.The QTLs are mainly distributed on chromosome 1,3,4,5,6,7,8,10 and 12 with major ones on chromosome 3 and chromosome 7.
