项目摘要

Soybean is currently the first largest field crop in Ontario and rapidly expanding in Canada. Soybean cyst nematode (SCN) is the largest threat to sustainable production of soybean in North America, including Canada. Growing soybean cultivars with diverse sources of the resistance is currently the most effective approach for controlling SCN pressure and increase the yield. The objectives of this collaborative project between the Ontario Ministry of Agriculture, Agriculture and Agri-Food Canada, Grain Farmers of Ontario, SeCan, and the University of Guelph are as follows. First, we will develop new high-yielding soybean cultivars with diverse sources of SCN through establishing breeding populations from crosses between Ontario-adapted elite cultivars and three main sources of SCN and selecting the best lines and germplasm. Second, we will identify genes underling the resistance to SCN in three sources and develop molecular-based selection tools. This work has economic, environmental and social impacts. For example, increased and diversified resistance to SCN, leading to higher realized yield in developed cultivars, are key to uptake by farmers. In light of the developed molecular-based selection tools, we and other interested soybean breeders will also facilitate the development of resilient SCN-resistant cultivars with expanded genetic diversity.
大豆目前是安大略省第一大大田作物,并在加拿大迅速扩大。大豆囊线虫(SCN)是包括加拿大在内的北美大豆可持续生产的最大威胁。培育具有多种抗SCN来源的大豆品种是目前控制SCN压力和提高产量的最有效途径。安大略省农业部、加拿大农业和农业食品部、安大略省粮食农民协会、SeCan和圭尔夫大学之间的合作项目的目标如下。首先,我们将通过建立安大略省适应优良品种与三个主要SCN来源杂交的育种群体,筛选最佳品系和种质,开发具有多种SCN来源的高产大豆新品种。其次,我们将在三个来源中鉴定出对SCN抗性的基因,并开发基于分子的选择工具。这项工作具有经济、环境和社会影响。例如,对SCN抗性的增强和多样化,导致发达品种实现更高的产量,是农民吸收的关键。基于已开发的分子选择工具,我们和其他感兴趣的大豆育种者也将促进具有扩大遗传多样性的抗scn抗性品种的开发。
