摘　　要：采用玉米开苞导入技术将不同基因型玉米自交系总DNA分别导入不同基因型受体玉米自交系中,得到了广泛的变异。不同基因型供体导入同一基因型受体后,后代大部分性状趋向于受体,而部分性状发生变异;同一基因型供体导入不同基因型受体后,后代大部分性状与供体对照相差显著;后代性状变异频率不同,但不同组合部分性状都发生了不同程度的变异。玉米的开苞导入技术对供体和受体的选择是不严格的。In this study, total DNA extracted from different donors were introduced into different receptors and gained broad variation. Experimentation results indicated that characters of some progenies inclined to receptors after introducing the DNA of different donors, some of variance occurred. The characters of progenies were notably discrepant with donors after introduced different receptors. But some characters of different combinations occurred different variation. Therefore, opening-bract transformation technology of maize was relaxed to donors and receptors.
