摘要: Two new partial amphiploids SN20 and SN122, derived from crosses between Elytrigia elongata and common wheat Yannong15 and Shannongfu63, were found resistant to powdery mildew, a serious fungal wheat disease. Cytogenetic observations showed that each SN20 and SN122 plant had 56 chromosomes. The chromosomes in most pollen mother cells formed approximately 28 bivalents, thereby showing a high degree of cytogenetic stability. Genomic in situ hybridization using St-genomic DNA from Pseudoroegneria strigosa as a probe and ABD-genomic DNA from Chinese Spring wheat as a blocker demonstrated that the genomic formulas for the alien chromosomes in SN20 and SN122 were 2 St+10 J(S)+2J and 2 St+8 J(S)+4J, respectively. These wheat E.elongata partial amphiploids represent a potential novel source of resistance to powdery mildew for wheat breeding.
