1 材料与方法 1.1材料 鲁麦5号——回交亲本,株高 80cm 左右,耐肥、抗倒性强,产量潜力达 500kg,高抗条锈和白粉病,兼抗叶锈和秆锈病,是一个优良性状较全面的高产品种。但最大的缺点是晚熟。以鲁麦5号为改良对象,以改良其晚熟缺点为主攻目标。 10个转育已基本稳定 (均为BC_3) 并各具不同早熟特点、农艺性状较好的材料。它们是:Tal金沙江3号、Tal 104-2、Tal 104-4、Tal向阳4号、Tal城辐752、Tal(蚰包/欧柔) M_3、Tal 18-1、Tal青4031、Tal 7031、Tal 1215-1-7-5-09。
1 Materials and methods 1.1 Materials Lumai 5 - back to the parent, about 80cm tall, resistant to fertilizer, lodging resistance strong, the yield potential of 500kg, high resistance to stripe rust and powdery mildew, and resistance to leaf rust and stem rust, Is a superior trait more comprehensive high-yielding varieties. But the biggest drawback is late maturity. Rumai 5 as the object of improvement, to improve its late-maturing shortcomings as the main target. Ten of them were basically stable (all BC_3) and had different characteristics of early maturity and better agronomic characters. These are: Tal Jinsha 3, Tal 104-2, Tal 104-4, Tal Xiangyang 4, Tal Chengxian 752, Tal (蚰 包 / 欧 柔) M_3, Tal 18-1, Tal 青 4031, Tal 7031 , Tal 1215-1-7-5-09.
