粒重是决定小麦产量的三因素之一,受多基因控制.本实验室前期研究在自然群体中发现27个粒重关联SSR位点.本研究运用石家庄8号和石4185衍生群体对这些关联位点的有效性和可重复性进行了验证,结合SSR位点基因型数据和分离群体2008年(河北赵县)、2009年(北京)、2010年(河北石家庄、河南洛阳)三年四点的田间表型鉴定数据,筛选到7个粒重相关SSR位点;对关联度最高SSR位点(cfd78)所在的染色体区域进行标记加密,获得与千粒重基因或QTL紧密连锁的SSR标记.

节节麦作为改良普通小麦的重要材料被广泛利用,其中具有的强休眠材料为小麦穗发芽抗性育种提供了大量基因资源.利用强休眠节节麦AS60,通过人工合成获得了六倍体小麦SHW-L1,利用四川地区推广品种川麦32与其杂交构建了重组自交系(F10)并获得高密度DArT图谱.

小麦穗发芽(Pre-harvest sprouting,PHS)是指收获前遇到阴雨或在潮湿环境下籽粒在穗上发芽的现象.穗发芽是一种世界性的重要灾害,主要发生在收获季节易降雨的地区.我国受穗发芽危害的麦区约占全国小麦总面积的83%.穗发芽不仅降低产量而且严重劣化品质和种用价值.
