摘　　要：本文阐明了我国北方 112个玉米自交系的秸秆粗蛋白质含量存在着明显差异 ,明确了差异因素虽与土壤肥力有关 ,但主要取决于玉米自交系的基因型差异。证实了玉米自交系秸秆和子实的粗蛋白质含量呈极显著的正相关 。Investigation results indicated that there are distinct different in straw crude protein content among 112 self-bred maize varieties Though soil fertility factors have some influences, the genotype decides to a great extent the crude protein contents of straw There are marked positive correlation between straw and seed crude protein contents This work provides the basis for screening high protein self-bred maize line and hybrid strain for grain and straw dual purposes
