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。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.
