Identification of a major QTL conferring resistance to <i>wheat yellow mosaic virus</i> derived from the winter wheat 'Hokkai 240' on chromosome 2AS.

ABSTRACT: Wheat yellow mosaic disease is a soilborne disease caused by wheat yellow mosaic virus (WYMV). Symptoms include yellow mosaic coloring of leaves, stunting, and growth inhibition. Here we conducted a detailed analysis of resistance to this virus in winter wheat 'Hokkai 240' by carrying out inoculation tests of WYMV and conducting field tests. The resistance level observed in 'Hokkai 240' was compared with those in varieties harboring known resistance genes. In the inoculation tests, 'Hokkai 240' showed resistance to WYMV Pathotypes I and II and partial resistance to Pathotype III. This result was contrary to the sensitive responses to the three pathotypes exhibited by the variety harboring resistance gene on chromosome 2DL. In fields infected with WYMV Pathotypes II and III, 'Hokkai
