摘要：
A Triticum durum - T. monococcum amphiploid (AABBA(m)A(m)) was synthesized by chromosome doubling of sterile triploid hybrids obtained between the two T durum cultivars Saturn-1 and Neptun-2, and one T monococcum ssp. aegilopoides (A(m)A(m)) accession. The two amphiploid lines, A1 and A2 with each durum cultivar, expressed resistance to wheat powdery mildews at seedling and adult stage, and to four leaf rust cultures, including isolate 22762 to which the diploid wild wheat was susceptible. The newly produced amphiploid could be a useful genetic resource for fungal resistance in wheat.
