| Outline of Final Research Achievements |
Wheat blast is a devastating disease that first arose in Brazil in 1985, then spread to neighboring countries in South America, to Asia (Bangladesh) in 2016, and to Africa (Zambia) in 2018. In the present study, we identified two factors involved in the development of hypervirulent isolates. Also, we screened about 520 local landraces of common wheat collected worldwide, and found a highly resistance line, GR119. Genetic analyses revealed that GR119 carried two resistance genes. One was Rmg8 which was previously identified in our laboratory, but the other was a new gene. The new gene was tentatively designated as RmgGR119. These two genes operated additively, and were effective against wheat blast isolates prevailing in Bangladesh.
