Goff is a plum listed by the University of Minnesota Agricultural Experiment Station as Prunus americana, the American plum. In the 1951 bulletin Pollination Studies with Stone Fruits, Goff appears in a table of hybrid and native plums rated as good pollinizers. The table credits it with pollinating 16 tested varieties and lists its bloom season as late. [S1]
The source does not give Goff's breeder, origin, release date, fruit description, or parentage. Its documented value is practical: it was tested for pollen performance in Minnesota stone fruit trials, where native and hybrid plums were compared for orchard compatibility. [S1]
For plum pollination, Goff was rated a good pollinizer. Its late bloom may have helped where bloom overlap was needed with later flowering plum varieties. [S1]
The same bulletin also lists Goff among varieties rated as poor pollinizers for cherry-plums. This does not conflict with its good rating for plums. The bulletin treats cherry-plums as a separate compatibility problem and states that success with one cherry-plum variety does not imply success with another. [S1]
Hardiness is not stated directly for Goff. The bulletin covers Minnesota and northern stone fruit planting. Its broader discussion excludes pure Prunus salicina and Prunus simonii as pollinizers because they lack winter hardiness. Goff's listing as P. americana places it in a native plum background relevant to northern plum culture, but the source gives no zone rating. [S1]
