Application of SNP genotyping and rapid screening procedures to enable commercialisation of faba bean varieties with stem nematode resistance

项目标题：应用SNP基因分型和快速筛选程序，使具有茎线虫抗性的蚕豆品种能够商业化摘要：茎线虫Ditylichus dipsai是英国蚕豆的主要害虫。它降低了产量和质量，而且它在土壤中的持久性对蚕豆生产造成了重大限制。蚕豆种质资源中已知抗性来源，但目前还没有适合英国及其市场的抗性品种。蚕豆分子标记产生的最新进展，以及对线虫抗性表型筛选的改进，为生物技术方法在开发抗线虫品种上的应用提供了机会。该项目的目标是确定与茎线虫抗性相关的标记，并验证它们在培育适应良好、高产和抗线虫的新一代蚕豆品种中的用途。

PROJECT TITLE: Application of SNP genotyping and rapid screening procedures to enable commercialisation of faba bean varieties with stem nematode resistanceSummary: Stem nematode, Ditylenchus dipsaci, is a major pest of Vicia faba beans in the UK. It reduces yield and quality, and its persistence in soil imposes a major constraint on faba production. Sources of resistances are known in faba bean germplasm, yet there are no resistant varieties available appropriate for the UK and its markets. Recent developments in the generation of molecular markers in faba bean, and improvements in phenotypic screens for nematode resistance provide an opportunity for the application of biotechnological approaches to the development of resistant varieties. The objectives of this project are to identify markers linked to stem nematode resistance and to validate their use in breeding a new generation of faba bean varieties that are well-adapted, high-yielding and nematode resistant.
