小麦新品系2-26中抗白粉病基因的遗传分析和RAPD标记
GENETIC ANALYSIS AND RAPD MARKERS OF POWDERY MILDEW RESISTANCE GENE IN WHEAT LINE 2-26
摘要
Abstract
Powdery mildew,caused by Blumeria Graminis f.sp.tritici,is one of the most important damaging diseases in many regions of the world.In present study,genetic analysis of resistance for powdery mildew in a stable wheat line 2-26,which was derived from the hybrid progeny between Triticum durum-Dasypyrum villosum amphiploid and common wheat,was carried out.The result indicated the powdery mildew resistance in line 2-26 is controlled by a single dominant gene and temporarily named Pm2-26.Molecular markers and bulked sergeant analysis were used to characterized the powdery mildew resistance gene.Two RAPD markers（SBSC2 and SBSI20） were found tightly linked to the resistance gene in line 2-26.These results provided a basis to further transfer into stable SCAR marker in future.In addition,the gene origin in line 2-26 and relationships with other resistance genes were also discussed in this paper.关键词
