Dura is a cherry-plum cultivar listed by the University of Minnesota Agricultural Experiment Station in a 1951 pollination study. The table describes it as a seedling of Sapa and includes it among 11 commonly grown cherry-plum varieties used for intercompatibility comparisons [S1].
In that study, Dura was rated a good pollinizer in tests on 6 varieties. Its bloom season and pollen abundance were both recorded as medium [S1].
