| 摘 要： | 应用247个株系组成的珍汕97B/密阳46重组自交系群体及其相应的含250个分子标记的高密度分子遗传图谱，通过复合区间作图法，对苗期水培和盐胁迫条件下水稻叶片叶绿素荧光参数进行了数量性状座位（QTL）分析。检测到控制水稻叶片叶绿素荧光参数（Fo、Fm和ΦPSⅡ）的7个主效应QTL，分布在水稻的第1、4、5和11染色体上，贡献率为598%～10.74%。其中,控制水培条件下Fm的QTL与控制盐胁迫下Fo的QTL均位于第5染色体的CDO82-RG413标记区间，说明此区间的QTL具有多效性，可同时影响Fm、Fo两个叶绿素荧光参数。

| Abstract: | By employing a recombinant inbred line (RIL) population consisting of 247 lines derived from an indica indica cross Zhenshan 97B×Milyang 46, a linkage map consisting of 250 DNA markers was constructed for QTL mapping of chlorophyll fluorescence parameters under normal conditions and salt stress (0.7% NaCl). Seven QTLs for chlorophyll fluorescence parameters (Fo, Fm and ΦPSⅡ) of rice leaf were detected on chromosomes 1, 4, 5 and 11 under normal conditions and salt stress, explaining 5.98% to 1074% of phenotypic variations. One QTL for Fm under normal conditions and one QTL for Fo under salt stress were located in the same interval CDO82-RG413 on chromosome 5, indicating the pleiotropism of this region. |
