摘　　要：本试验对BN61、DN 62、N 455、H 6等100个糯玉米自交系的主要农艺性状的遗传变异及相关性进行了研究。自交系间存在较高的遗传变异。株高、穗位、穗长、穗粗、行粒数与穗重呈极显著正相关, 通过对主要农艺性状的分析, 并筛选出山东971335 2, 山东971353 4等16个综合性状优良自交系, 可作为北京地区糯玉米育种的素材。In this experiment, I had analyzed the genetics and the variation of the main agronomic characteristics of 100 waxy-maize’s inbred lines.The 100 inbred lines were BN61、DN-62、N-455、H-6 and so on.The genetics and the variation have a high frequency in Inbred lines Analyzing the main agronomic characteristics of the waxy-maize inbred lines by correlation, the results have indicated that plant height、ear height、ear length、ear diameter and kernel row have significant effect to weight per ear.And 16 inbred lines which have a synthetically good characteristics were called for example shandong971335-2,shandong971353-4 and so on.
