Soybean mosaic virus （SMV） is one of the most serious diseases affecting soy-bean yield. Recombination inbred lines （RILs） are common materials for resistance genetic research. However, the population construction always takes quite a long time which pro-long the breading process. Shoot-cutting is a well-established technique for plant multipli-cation. It has high successful ratio in soybean. In this study, we use shoot-cutting to multiply two F2 populations from the crosses of susceptible and resistant varieties. Soybean plants can be multiplied from 1 into 3 homogenous ones within 30 days, bringing on well-grown plants with normal seeds. The SMV resistance from cutting-shoot plants was consistent with that from original plants. When shoot-cutting is applied in a F2 population, the pheno-typic and genotypic data can be simultaneously collected and corresponding saved during population development. The genetic research and resistant breeding can be effectively promoted by this technology.

锦屏一级水电站坝区山高坡陡,两岸山体地应力高,左岸存在深部裂缝、低波速松弛岩体、煌斑岩脉(X)及f2,f5断层等复杂地质条件。为对左岸边坡深部岩体微震活动性进行实时监测和分析,2009年6月该边坡安装加拿大ESG公司生产的微震监测系统。通过构建左岸边坡三维地质模型和优化传感器布设方案,采用人工定点爆破试验对监测系统定位性能进行测试,结果显示在传感器阵列范围内的震源定位误差小于12m,证明系统具有较高的定位精度。对拾取的事件波形进行分析和聚类研究,给出系统运行以来微震事件的时空分布规律,初步圈定左岸边坡微震活动引起的深部岩体变形区域,并结合RFPA有限元软件对比研究边坡应力场和潜在滑裂面。研究结果表明,该边坡微震监测系统的设计和实施满足深部岩体变形的全局监测,能够识别左岸边坡可能存在的潜在岩体破坏区域和滑移面,为边坡后期生产性灌浆以及加固处理提供一些参考,也为高岩质边坡稳定性分析提供一个新的研究思路。
