紫花苜蓿品种龙牧803风干种子在室温下经零磁空间处理6个月,在田间通过系统选择,结合返青期、返青率、株高、干草产量、粗蛋白质含量、抗病性等指标的检测,选育出紫花苜蓿新品系LS0301。进行了多点、多年田间比较试验表明,LS0301比亲本返青早1-3d,返青率提高1%-2%,株高提高4.94%,干草产量提高17.94%,粗蛋白质含量提高5.01%,表现对苜蓿褐斑病、白粉病有一定的抗性。2006年LS0301通过黑龙江省农作物品种审定委员会的认定推广,定名为农菁1号。RAPD分析结果显示,龙牧803与LS0301在不同引物的扩增下显示出差异,表明零磁空间可以作为一种有效的育种手段。
The alfalfa variety Longmu 803 dried seeds were treated in the zero-magnetic space at room temperature for 6 months. Through the system selection, combined with the detection of rejuvenation, greening rate, plant height, hay yield, crude protein content, disease resistance and other indicators , Bred a new alfalfa line LS0301. The results showed that LS0301 was 1-3 days earlier than the parents and the rejuvenation rate increased by 1-2%, the plant height increased by 4.94%, the hay yield increased by 17.94% and the crude protein content increased by 5.01% Alfalfa leaf spot, powdery mildew have some resistance. In 2006, LS0301 was approved by Heilongjiang Crop Variety Approval Committee and named as No.1. The results of RAPD analysis showed that Longmu 803 and LS0301 showed the difference under the different primers, indicating that zero-magnetic space could be used as an effective breeding method.
