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.

目的探讨口腔健康状态与颈动脉内膜中层厚度(carotid intima⁃media thickness,cIMT)的关系,以及血清同型半胱氨酸(homo⁃cysteine,HCY)在其中的中介作用。方法利用2019年6月15日―2020年1月12日浙江省绍兴市某医院体检项目参与者数据,将691名≥50岁具备完整的口腔检查结果、cIMT检查结论及相关数据者作为研究对象。采用多因素logistic回归分析模型分析口腔健康状态与cIMT的关联。采用Bootstrap方法检验血清HCY在口腔健康状态和cIMT关系中的中介效应。结果多因素logistic回归分析模型调整协变量后,口腔不健康组检出cIMT增厚的可能性是口腔健康组的2.04倍(OR=2.04,95%CI:1.48~2.81)。中介效应分析结果显示,血清HCY在口腔健康状态与cIMT的关联中发挥了部分中介效应(间接效应=0.04,95%CI:0.01~0.06,P<0.001),占总效应的21.89%(P<0.001)。结论口腔不健康状态可能与cIMT增厚相关,且血清HCY在其中发挥了一定的中介作用。

To reveal origins of 316 state authorized varieties from 1984 to 2013, rules of their parentsJ selection including types and hybrid configurations of direct parents, geo-graphical sources and types of their ancestors were analyzed. Various important direct parents and ancestors were summarized and nuclear contribution of ancestors was also estimated by pedigree analysis. Among 316 registered cultivars, 298 （94.3%） were bred by hybridization, and most of their direct parents were cultivars or breeding lines （65.5%）. Cultivars and breeding lines were mostly used as female parents, with 53.0% and 38.7% respectively. The 316 released cultivars were traced to 373 final ancestors, mainly com-posed of landraces （55.5%） and breeding lines （36.7%）. The 373 final ancestors came from different regions, including 121 from northern area, 110 from huang-Huai-Hai area, 53 from southern area and 76 from abroad. These ancestors were mainly from the same ecologic zone as the approved cultivars. Newly approved cultivars always have more ancestors and a broader genetic base. However, distribution of these ancestors was unbalanced, and a few ancestors provided significant genetic contributions to later generations, such as the most concentrated final ancestors from huang-Huai-Hai region followed by northern and southern regions. These results offer more information regarding their important parents and provide valuable references to soybean breeding. We should increase soybean germplasm exchanges with different regions and make use of elite lines, foreign cultivars and wild soybean germplasm to broaden the genetic background.
