Development and Characterization of Triticum aestivum-Aegilops longissima 6S^l Recombinants Harboring a Novel Powdery Mildew Resistance Gene Pm6Sl.

ABSTRACT: Powdery mildew of wheat is a foliar disease that is spread worldwide. Cultivation of resistant varieties is the most effective, economical, and environmentally friendly strategy to curb this disease. Powdery mildew resistance genes (Pm) are the primary resources for resistance breeding, and new Pm genes are in constant demand. Previously, we identified Aegilops longissima chromosome 6S^l#3 as a carrier of powdery mildew resistance and designated the resistance gene as Pm6Sl. Here, we reported the design of 24 markers specific to 6S^l#3 on the basis of the full-length cDNA sequences of 6S^l#3 donor Ae. longissma accession TA1910, and the development of wheat-Ae. longissima 6S^l#3 introgression stocks by
