| 摘 要： | 为了研究小麦穗发芽的抗性水平，揭示其遗传机理，并筛选抗性较强的家系用于育种实践，利用黄淮海地区主要推广的两个小麦品种花培3号／豫麦57构建的DH群体和基于混合线性模型的QTLNetwork2．0软件，对3种环境下的小麦整穗发芽进行了QTL定位分析。3种环境条件下分别检测到3、3、2个与整穗发芽相关的加性QTL位点，这些位点分别位于1B、2B、4A和5D染色体上，总共可解释23．28％、21．83％和11．55％的表型变异。在所有检测到的QTL位点中，只有qPhsSD．1位点在3个环境中均能检测到，剩余位点只能在单独一个环境中检测到。3种环境条件下分别检测到2对、1对和2对上位性位点，总共可解释8．01％、9．50％和21．67％的表型变异，不同环境条件下，检测到的上位性位点均不相同。结果表明，小麦整穗发芽的遗传同时受加性效应和上位性效应控制，且易受环境条件的影响。

| Abstract: | In order to study the resistance level of pre-harvest sprouting in wheat,reveal its genetic mechanism and choose the lines with high level resistance for breeding practices,the quantitative trait loci(QTLs) analysis for pre-harvest sprouting using intact spikes were conducted using a doubled haploid(DH) population lines derived from a cross between two wheat cultivars Huapei 3/Yumai 57 which are planted over a large area in the Huang-Huai Wheat Region.QTL analysis were performed using the mixed linear model... |
