摘要
本研究测定了我国北方地区近期主要推广种植的13个玉米杂交种(含一个高油品种)的粗蛋白、粗脂肪、赖氨酸和水溶性糖的含量。借助计算机用系统聚类法按单项指标和4项指标对供试品种进行了分类,并讨论了我国玉米品质改良的意义和目标。
In this paper, thirteen commercially grown maize hybrids (including a high oil cultivar) in the north of China were used. The crude protein, crude fat, lysine and water souble sugar were measured. The maize hybrids were classified reasonably on a computer in accordance of the cluster analysis of each and four indexes mentioned above. The significance and the objectives of maize quality improvement were also discussed.
