摘要:
生育期是玉米重要的性状之一,其中抽穗期、散粉期和吐丝期是3个最重要的指标。以玉米自交系LDC-1和YS501构建的186个重组自交系为材料,在2个大田种植环境下对抽穗期、散粉期和吐丝期3个生育期相关性状进行QTL解析。基于Maize10k芯片数据构建总长为2 569.89 cM的高密度遗传图谱,共包含2 624个bin,相邻标记间的平均距离为0.98 cM。共检测到32个生育期相关性状QTLs,似然函数比值对数值(logarithm of odds,简称LOD)为2.52~10.86,贡献了3.33%~17.19%的表型变异。其中qDTT9-1、qDTS9-2在不同环境中稳定表达且效应较大,在育种中可能具有较大利用价值。本研究结果可为进一步精细定位生育期相关性状QTLs和利用分子标记辅助选择开展品种改良提供参考。
