A pleiotropic QTL increased Q1 economic water use efficiency in bread wheat (Triticum aestivum L.)

In this study, a high-density genetic linkage map of wheat recombinant inbred lines (Ningchun 4 x Ningchun 27) containing 8751 specific locus amplified fragment (SLAF) tags (including 14757 SNPs), with a total map distance of 1685 cM and an average inter-marker map distance of 0.19 cM was constructed by SLAF-seq technology.

本研究通过SLAF-seq技术，构建了小麦重组自交系（宁春4号×宁春27号）的高密度遗传连锁图谱。该图谱包含8751个特异性位点扩增片段（SLAF）标签，涵盖14757个单核苷酸多态性（Single Nucleotide Polymorphisms, SNPs），总遗传距离达1685 cM，标记间平均遗传间距为0.19 cM。
