| Abstract: | Amisk was registered in Canada as a clonal variant of Ranger Russet in 1993. Amisk is similar to Ranger Russet in foliage and tuber morphology and DNA analysis did not detect a polymorphism. However, under Canadian prairie conditions, four years of field data indicate that the yield and number of tubers >88 mm is higher for the Amisk clone than for the 1982 clone of Ranger Russet, second growth occurs less frequently and Amisk is more resistant to tuber invasion by verticillium and fusarium wilt pathogens. |
