宁麦9号与扬麦158株高及其构成因素的遗传解析

Key Words:小麦, 宁麦9号, 扬麦158, 株高, KASP标记

Abstract:宁麦9号与扬麦158是我国长江中下游麦区的主栽品种和骨干亲本, 长江中下游麦区近3年来审定品种中80%都是其衍生后代, 研究其性状的遗传具重要意义。以宁麦9号与扬麦158为亲本构建的包含282个家系的重组自交系群体为材料, 利用Illumina 90k芯片对群体进行基因型分析, 建立高密度遗传图谱。连续3个生长季对株高及节间长度、穗长等株高构成因素进行测定, 结合遗传图谱对株高及相关性状进行QTL定位, 获得14个控制株高及其构成因素的稳定表达位点。通过进一步位置比对, 聚焦到6个染色体区段, 初步明确了各节间对株高的遗传调控机制。同时, 将6个染色体区段中同源性较低的连锁标记转化为适用于高通量筛选的KASP标记, 利用101份区域试验材料进行标记效应验证, 结果显示聚合Qph-2D与Qph-5A.1两个位点具有较高的选择效率, 继续聚合Q2A后, 中选材料显著减少, 可能降低选择效率; 对Q2A与Q5A两个一因多效位点的选择建议以降低株高的等位变异为主; Qd1-5D可作为穗下节间(D1)的选择标记对株高展开优化选择。期望以上结果能为长江中下游麦区的小麦株高遗传改良提供帮助
