小麦叶绿素荧光和色素性状的遗传控制及其与生物量生产力的关系目前还知之甚少。在最佳温室条件下，对中国春× SQ 1的94个品系的加倍单倍体群体进行了4年的试验，以鉴定CF性状的数量性状位点（QTL），包括首次在小麦中鉴定的每个激发截面的JIP检验参数（CSm）：ABS/CSm、DIo/CSm、TRo/CSm、RC/CSm和ETo/CSm是决定光合机构效率的关键参数，以及叶绿素和类胡萝卜素含量，以建立与生物量和谷物产量的关联。通过添加多样性阵列技术标记，将现有的遗传图谱扩展到920个位点。标记和光合光反应，色素代谢和生物量积累的基因被定位到染色体缺失箱。在除7B外的所有染色体上共检测到116个CF QTL，在除1A、2A、4A、3B、5B、1D、2D、5D、6D和7D外的大多数染色体上共检测到39个色素QTL。将30个与植物生产力相关的QTL定位在3A、5A、6A、7A、1B、2B、4B、6B、7B、3D和4D染色体上。在第6B染色体上发现了一个区域，其中14个CF参数QTL与叶绿素含量和穗粒重QTL相吻合。35个QTL区域与候选基因一致。环境被证明在决定这些性状的基因表达方面占主导地位。本文的在线版本（doi：10.1007/s11032 - 013 - 9862 - 8）包含补充材料，可供授权用户使用。
Relatively little is known of the genetic control of chlorophyll fluorescence (CF) and pigment traits important in determining efficiency of photosynthesis in wheat and its association with biomass productivity. A doubled haploid population of 94 lines from the wheat cross Chinese Spring × SQ1 was trialled under optimum glasshouse conditions for 4 years to identify quantitative trait loci (QTL) for CF traits including, for the first time in wheat, JIP-test parameters per excited cross section (CSm): ABS/CSm, DIo/CSm, TRo/CSm, RC/CSm and ETo/CSm, key parameters determining efficiency of the photosynthetic apparatus, as well as chlorophyll and carotenoid contents to establish associations with biomass and grain yield. The existing genetic map was extended to 920 loci by adding Diversity Arrays Technology markers. Markers and selected genes for photosynthetic light reactions, pigment metabolism and biomass accumulation were located to chromosome deletion bins. Across all CF traits and years, 116 QTL for CF were located on all chromosomes except 7B, and 39 QTL were identified for pigments on the majority of chromosomes, excluding 1A, 2A, 4A, 3B, 5B, 1D, 2D, 5D, 6D and 7D. Thirty QTL for plant productivity traits were mapped on chromosomes 3A, 5A, 6A, 7A, 1B, 2B, 4B, 6B, 7B, 3D and 4D. A region on chromosome 6B was identified where 14 QTL for CF parameters coincided with QTL for chlorophyll content and grain weight per ear. Thirty-five QTL regions were coincident with candidate genes. The environment was shown to dominate in determining expression of genes for those traits.
