Development and characterization of wheat yellow mosaic virus-resistant lines carrying Q.Ymym, breaking off the tightly-linked high-activity allele of the polyphenol oxidase gene in the Japanese wheat variety ‘Yumechikara’

The Japanese winter wheat variety ‘ Yumechikara ’ shows resistance to wheat yellow mosaic virus (WYMV). A single major QTL for WYMV resistance, Q.Ymym, has been identified in ‘ Yumechikara ’ . Q.Ymym is tightly linked with the high-activity allele of the polyphenol oxidase (PPO) gene, Ppo-D1b, on th...
