Alternaria black spot and Fusarium wilt are problematic diseases affecting strawberry production in Akita Prefecture in northern Japan. In this study, we aimed to address these diseases from the perspective of breeding. The strawberry cultivar “Morioka-16” , which is commonly cultivated in northern Japan, bears large fruits that are of excellent quality. However, this cultivar is particularly susceptible to Alternaria black spot. We attempted to develop an improved “Morioka-16” line that is resistant to the disease using somaclonal variations induced during tissue culture. Using this method, we succeeded in generating three resistant lines, “M16-AR 1” , “M16-AR 2” and “M16-AR 3” . The “M16-AR 2”
line developed in this study was registered as a new cultivar named “Akita Berry” and was introduced to strawberry-producing districts in Akita Prefecture. Further, to develop a new cultivar resistant to Fusarium wilt, we crossed the “Pajaro” and “Belle Rouge” cultivars. Three resistant lines, namely “WB-A15” , “WB-B22” and “WB-B33” were selected from the resulting F1 seedlings. Among these, “WB-B33” which retained a high crop yield, was registered as a new cultivar named “Komachi Berry” and introduced to strawberry-producing districts in Akita Prefecture.
Although “WB-A15” and “WB-B22” were not registered as cultivars, they were given the names “Harumi” and “New Harumi” respectively, and provided to various growers and cultivated throughout Akita Prefecture.
