| 摘 要： | 用大穗高秆品种Ａｋｅｎｏｈｏｓｈｉ与半矮生粳型系统ＳＣ－ＴＮ１杂交后代Ｆ５的６个品系及其亲本为材料，比较分析了品系与亲本遗传性状的表现及其联系。结果表明，通过改善ｓｄ－１基因的遗传背景，使半矮生性及优良株型的特性与大库容量相结合是可能的，能够从中培育出有更高产量潜力的新品系

| Abstract: | Using six F 5 lines gotten from hybridization between large ear,long stalked variety Akenohoshi and semi dwarf variety SC TN 1,and their parents as tested material,the relationships of their genetic characteristics were studied.The results indicated that it was possible to integrate semi dwarf character and large metabolic pool character through improving genetic background of sd 1 gene and the new lines with higher yield could be bred. |
