摘要: 为了对玉米的抗旱遗传学研究以及开展抗旱分子标记辅助育种提供有力支撑,利用SSR分子标记技术,构建了玉米基于RIL6群体的遗传连锁图谱,包含101个位点,覆盖玉米基因组1395.2 cM,标记间平均距离为13.81 cM。在灌溉与干旱两种环境下,对该RIL家系的株高、产量进行QTL初级定位,在灌溉条件下,检测到3个控制株高和3个控制产量的QTL,在干旱条件下,检测到个控制株高和3个控制产量的QTL,两种水分条件下检测出的QTL不同,并找到1个相对稳定的QTL。

Abstract: Genetic linkage map of maize groups based on RILs was developed by using simple sequence repeat (SSR) markers. The genetic map contained 101 positions, covered with 1396.2 cM in genome of maize, and the average distance was 13.81 cM. The plant height and yield of RIL lines under irrigation and drought condition were primarily mapped. Under irrigation condition, 3 QTL positions controlled plant height and 3 QTL positions controlled yield were detected. Under drought condition, 5 QTL positions controlled plant height and 3 QTL positions controlled yield were detected. QTL positions were different under different water condition, and 1 relatively stable QTL position was found. The aim of this study was to provide more support for genetics analysis of maize drought tolerance and its molecular marker assistance selection.

Key words: Maize, Drought, Plant height, Yield, QTL
