Favorable allele frequencies of the additive main QTLs for yield and yield-related traits in four 1000 grain weight (gw) - grain number per spike (gn) groups of wheat DH lines.

1YP (g): Yield per plant; NSP: Number of spikes per plant; NGS: Number of grains per spike; TGW (g): 1000-grain weight; TNSS: Total number of spikelets per spike; NSSS: Number of sterile spikelets per spike; PFSS: Proportion of fertile spikelets per spike; SL (cm): Spike length; DSS: Density of spikelets per spike; PH (cm): Plant height;2The nearest marker of the associated QTL;3The parent contributing the favourite allele of QTL;4QTL favourite allele frequence in a group, viz, for a special marker, the number of favourite allele divided by the total line number. Approximately the value 0.70 is considered that the favourite allele is rich in the group, which is expressed in bold print.

1. 单株产量（Yield per plant，缩写YP，单位g）；单株穗数（Number of spikes per plant，缩写NSP）；每穗粒数（Number of grains per spike，缩写NGS）；千粒重（1000-grain weight，缩写TGW，单位g）；每穗总小穗数（Total number of spikelets per spike，缩写TNSS）；每穗不育小穗数（Number of sterile spikelets per spike，缩写NSSS）；每穗可育小穗比例（Proportion of fertile spikelets per spike，缩写PFSS）；穗长（Spike length，缩写SL，单位cm）；小穗密度（Density of spikelets per spike，缩写DSS）；株高（Plant height，缩写PH，单位cm）；
2. 关联数量性状位点（Quantitative Trait Locus，QTL）的最近标记；
3. 贡献该QTL有利等位基因的亲本；
4. 群体内QTL有利等位基因频率，即针对某一特定标记，有利等位基因数与总株系数的比值。通常将0.70左右的数值判定为该有利等位基因在群体中富集，此类结果以加粗字体标注。
