In order to further explore the quantitative trait locus (QTL) for tillering-related traits in wheat, and to explore the genetic relationship between tillering traits, we used 255 recombinant inbred lines (RIL) populations, constructed from Apache and Xindong 36, as research materials to determine several key metrics. These included the number of pre-winter tillers, the number of single tillers, the number of effective tillers, the effective tillers per unit area, and the tiller angle. The phenotypic values of spike rate were determined in four environments. The QTL controlling tillering-related traits was carried out based on the ultra-low depth sequencing data of the RIL populations. The results showed that a total of 53 QTLs for tillering traits were detected on 15 chromosomes, including 13 QTLs for pre-winter tiller number, 10 QTLs for single-plant tiller number, 8 QTLs for effective tiller number per plant, 11 QTLs for effective tiller number per unit area, 4 QTLs for tiller angle, 2 QTLs for spike-forming rate, and 5 pleiotropism QTLs. The phenotypic interpretation rates of individual QTLs ranged from 2.66% to 28.76%. Among them, QTn.xjau-4B was detected in all three environments, with a phenotypic contribution rate of 28.76% to the effective number of tillers of a single plant. This stable QTL is a major effective and R-E-Z locus, which can be used as an important locus for the study of tillering and plant type.

为进一步挖掘小麦分蘖相关性状的数量性状位点(QTL),探索分蘖性状之间的遗传关系,以分蘖性状差异较大的小麦品种Apache和新冬36号构建的255 份重组自交系群体(RIL)为材料,分别测定其在4个环境下的冬前分蘖数、单株分蘖数、单株有效分蘖数、单位面积有效分蘖数、分蘖角度、成穗率表型值,并基于RIL群体的超低深度测序数据进行分蘖相关性状QTL定位。结果表明,除1D、2D、3B、4D、7A和7B染色体外,在其他15 条染色体上共检测到53个分蘖性状相关的QTL,包括13个冬前分蘖数QTL、10个单株分蘖数QTL、8个单株有效分蘖数QTL、11个单位面积有效分蘖数QTL、4个分蘖角度QTL、2个成穗率QTL和5个一因多效的QTL,单个QTL的表型解释率为2.66%~28.76%。其中,QTn.xjau-4B在3个环境下均被检测到,对单株有效分蘖数表型贡献率为28.76%,为稳定主效QTL,同时也是R-E-Z位点,后续可作为研究分蘖及株型的重要位点。

为进一步挖掘小麦分蘖相关性状的数量性状位点(QTL),探索分蘖性状之间的遗传关系,以分蘖性状差异较大的小麦品种Apache和新冬36号构建的255 份重组自交系群体(RIL)为材料,分别测定其在4个环境下的冬前分蘖数、单株分蘖数、单株有效分蘖数、单位面积有效分蘖数、分蘖角度、成穗率表型值,并基于RIL群体的超低深度测序数据进行分蘖相关性状QTL定位。结果表明,除1D、2D、3B、4D、7A和7B染色体外,在其他15 条染色体上共检测到53个分蘖性状相关的QTL,包括13个冬前分蘖数QTL、10个单株分蘖数QTL、8个单株有效分蘖数QTL、11个单位面积有效分蘖数QTL、4个分蘖角度QTL、2个成穗率QTL和5个一因多效的QTL,单个QTL的表型解释率为2.66%~28.76%。其中,QTn.xjau-4B在3个环境下均被检测到,对单株有效分蘖数表型贡献率为28.76%,为稳定主效QTL,同时也是R-E-Z位点,后续可作为研究分蘖及株型的重要位点。

In order to further explore the quantitative trait locus (QTL) for tillering-related traits in wheat, and to explore the genetic relationship between tillering traits, we used 255 recombinant inbred lines (RIL) populations, constructed from Apache and Xindong 36, as research materials to determine several key metrics. These included the number of pre-winter tillers, the number of single tillers, the number of effective tillers, the effective tillers per unit area, and the tiller angle. The phenotypic values of spike rate were determined in four environments. The QTL controlling tillering-related traits was carried out based on the ultra-low depth sequencing data of the RIL populations. The results showed that a total of 53 QTLs for tillering traits were detected on 15 chromosomes, including 13 QTLs for pre-winter tiller number, 10 QTLs for single-plant tiller number, 8 QTLs for effective tiller number per plant, 11 QTLs for effective tiller number per unit area, 4 QTLs for tiller angle, 2 QTLs for spike-forming rate, and 5 pleiotropism QTLs. The phenotypic interpretation rates of individual QTLs ranged from 2.66% to 28.76%. Among them, QTn.xjau-4B was detected in all three environments, with a phenotypic contribution rate of 28.76% to the effective number of tillers of a single plant. This stable QTL is a major effective and R-E-Z locus, which can be used as an important locus for the study of tillering and plant type.
