【摘要】 小麦籽粒中的类胡萝卜素具有较高的营养价值,对人类健康具有重要作用。测定了96个小麦品种资源的类胡萝卜素含量,品种间均达到极显著差异,两年类胡萝卜素含量相关达到极显著水平（r=0.66,R²=0.436）,说明两年品种间差异顺序基本一致,认为类胡萝卜素含量主要受遗传控制。F₂代群体遗传分析表明,类胡萝卜素含量主要受一对主基因控制。利用"山农01-35×藁城9411"重组自交系群体及其构建的小麦遗传图谱,检测到控制小麦类胡萝卜素含量的14个加性QTL和13对上位性QTL位点,对表型变异的贡献率为2.74%-17.03%。更多还原

【Abstract】 The wheat carotenoid has higher nutritive value and important function on humam health.Our research showed there are highly significant difference among 93 wheat varities and correlation between two planting years.These results indicated the carotenoid content is controlled genetically.The genetic analysis on F₂population indicated that carotenoid content was controlled by onepair major genes.Based on "Shangdong01-35×haocheng9411" RIL population and its genetic map,A total of 14 additive QTL and 13 upper QTL were detected.accounting for 11.65%⁶5.84%ofthe phenotypic variance.更多还原
