Convoy is a cherry-plum. The University of Minnesota pollination bulletin describes it as a sand cherry or Prunus besseyi hybrid. In plum and cherry-plum compatibility tests, it appears mainly as a pollinizer, not as a fruit described for eating quality. The bulletin calls it a new Canadian variety and says it was not yet widely available in the United States in 1951. [S1]
The source does not give Convoy's breeder, exact parentage, release year, or fruit description. It places the cultivar in the northern plum and cherry-plum breeding context, where Minnesota and Canadian breeders were producing hybrids for short season regions. Convoy appears in practical orchard recommendations for cherry-plums and is paired with Compass in one recommended planting row. [S1]
Convoy's clearest documented trait is its value as a pollinizer. In the cherry-plum tables, it was rated good as a pollinizer in tests on eight varieties. It had medium bloom and good pollen abundance. The text says Convoy was the only pollinizer rated good on every variety on which it had been tested, though the authors noted that this covered only eight test combinations. [S1]
The same bulletin also lists Convoy among hybrid and native plums rated as good pollinizers. There it is described as a P. besseyi hybrid, late blooming, and able to pollinate three tested varieties. The late bloom rating in the plum table and medium bloom rating in the cherry-plum table should be read as table-specific reports, not as a full bloom profile. [S1]
For orchard use, Convoy was included in the selected group of commonly grown cherry-plums used in the bulletin's compatibility table. It was also included in the smaller recommended planting group for home or commercial plantings. Table 14 reports Compass, Sapalta, and Sapa as good pollinizers for Convoy; Oka and Manor as fair; and Opata as poor. Convoy is recorded as a good pollinizer for Sapalta, Opata, Oka, Manor, and Sapa. [S1]
No direct cold hardiness zone is given for Convoy. Its hardiness context is indirect. The source is a Minnesota Agricultural Experiment Station bulletin on stone fruits for northern regions, and it describes Convoy as a Canadian cherry-plum variety used in northern pollination planning. The bulletin also says pure P. salicina and P. simonii plums were not tested as pollinizers because they lacked winter hardiness. Convoy is placed instead among the hardier hybrid material considered practical for this work. [S1]
The main uncertainty is identity detail beyond pollination behavior. The packet supports Convoy as a cherry-plum and sand cherry or P. besseyi hybrid, but it does not give a named cross, breeder, release date, fruit color, flavor, ripening season, storage quality, or disease observations. [S1]
