| 摘 要： | 高直链淀粉玉米品种选育具有广阔的应用前景和商业价值，目前，我国高直链淀粉玉米种质稀缺。显性Ae1-5180突变基因为直链淀粉扩充者ae的等位突变，对其育种应用研究鲜少报道。以10组优质玉米自交系及其Ae1-5180近等基因系为试验材料，通过对植株农艺性状和子粒品质分析发现，与对照相比，全部Ae1-5180近等基因系直链淀粉含量显著提高，同时总淀粉及百粒重降低。近等基因系CA240/Ae1和CANS-1/Ae1直链淀粉含量高，且百粒重较高，农艺性状变化小，推测具有较高的潜在育种价值。

| Abstract: | The breeding of high amylose maize lines has broad application prospects and commercial value. Currently, there is a scarcity of high amylose maize germplasm in China. The dominant Ae1-5180 mutant gene is an allelic mutation of amylose expander ae, however, research on its breeding application is rarely reported. In this study, 10 pairs of high-quality maize inbred lines and their Ae1-5180 near-isogenic lines were used as experimental materials to analyze the agronomic traits and grain quality of plants. The results showed that, compared with the control, the amylose content of all Ae1-5180 near-isogenic lines significantly increased, while the total starch and 100-grain weight decreased. The near-isogenic lines CA240/Ae1 and CANS-1/Ae1 exhibited high amylose content, high 100-grain weight and small changes in agronomic traits |
