高轻的导致的 photooxidation (HLIP ) 通常导致叶在冬季小麦的早熟的老朽和原因伟人收益损失。为了探索小麦公差的基因控制到 HLIP，强调，量的特点 loci (QTL ) 分析在一套加倍的 haploid 人口上被进行，源于二冬季小麦栽培变种。叶绿素内容(Chl ) 的实际价值，最小的荧光水平(Fo ) ，最大的荧光水平(Fm ) ，和在 HLIP 和非压力条件以及到非压力的 HLIP 的比率下面的 photosystem II (Fv/Fm ) 的最大的量效率被评估。HLIP 更加在非压力状况下面减少了 Chl， Fm，和 Fv/Fm，但是增加了 Fo，与那相比。27， 16，和 28 QTL 的一个总数分别地在 HLIP 和非压力和 HLIP 的比率下面与调查特点被联系到非压力。大多数为到并置或将近连接了，那些在 HLIP 状况下面检测了的非压力的 HLIP 的比率的 QTL。 导致HLIP 的 QTL 在 15 个染色体上被印射当在非压力状况下面表示的那些在九包含了染色体时，在 1A 1B ， 1D ， 2A ， 2B ， 2D ， 3A ， 3B ， 4A ， 4D ， 5B ， 6A ， 6B ， 7A ，和 7D 包含包括 1B ， 1D ， 2A 2B 3B 4A 5A 5B 和 7A 。在 HLIP 状况下面的 QTL 的表示模式除了五个染色体上的六 loci 在非压力状况下面与那不同。单个 QTL 解释的 phenotypic 变化在 HLIP 下面从 5.0% ～ 19.7%， 8.3% ～ 20.8% 在非压力下面，并且 4.9% ～ 20.2% 为到非压力的 HLIP 的比率分别地。例如，在 HLIP 下面调整 Chl， Fo， Fm，和 Fv/Fm 的 4D 上的 Xgwm192 和 WMC331 调节的一些标记，可能在标记助手选择被使用。

英文摘要：

High light induced photooxidation （HLIP） usually leads to leaf premature senescence and causes great yield loss in winter wheat. In order to explore the genetic control of wheat tolerance to HLIP stress, a quantitative trait loci （QTL） analysis was conducted on a set of doubled haploid population, derived from two winter wheat cultivars. Actual values of chlorophyll content （Chl）, minimum fluorescence level （Fo）, maximum fluorescence level （Fm）, and the maximum quan~m efficiency of photosystem II （Fv/Fm） under both HLIP and non-stress conditions as well as the ratios of HLIP to non-stress were evaluated. HLIP considerably reduced Chl, Fm, and Fv/Fm, but in- creased Fo, compared with that under non-stress condition. A total of 27, 16, and 28 QTLs were associated with the investigated traits under HLIP and non-stress and the ratios of HLIP to non-stress, respectively. Most of the QTLs for the ratios of HLIP to non-stress collocated or nearly linked with those detected under HLIP condition. HLIP-induced QTLs were mapped on 15 chromosomes, involving in 1A, 1B, 1D, 2A, 2B, 2D, 3A, 3B, 4A, 4D, 5B, 6A, 6B, 7A, and 7D while those expressed under non-stress condition involved in nine chromosomes, includ- ing 1B, 1D, 2A, 2B, 3B, 4A, 5A, 5B, and 7A. The expression patterns of QTLs under HLIP condition were different from that under non-stress condition except for six loci on five chromosomes. The phenotypic variance explained by individual QTL ranged from 5.0% to 19.7% under HLIP, 8.3% to 20.8% under non-stress, and 4.9% to 20.2% for the ratios of HLIP to non-stress, respectively. Some markers, for example, Xgwm192 and WMC331 on 4D regulating Chl, Fo, Fm, and Fv/Fm under HLIP condition, might be used in marker assistant selection.
