S. D. Bona is a South Dakota crabapple selection. A 1938 record gives it as a cross of Jonathan apple and Sylvia crab. It appears in N. E. Hansen's hardy fruit bulletin as part of the program's work to improve the Siberian crabapple, which places it in the South Dakota experiment breeding program rather than as a chance local variety. [S1]
The bulletin describes S. D. Bona as a sister to S. D. Bison, though the scan cuts off the sister reference before the full name is fully legible. Hansen also noted that several more seedlings from the same cross were of good quality, which suggests this cross produced a broader family of promising selections. [S1]
The fruit is small, about 1 1/2 inches across and 1 1/4 inches deep. The skin is a deep polished red, described as nearly black red. The flesh is yellow, rich, mild, and pleasantly subacid. It was valued for cooking as well as appearance, because it cooks easily into a red sauce of very good quality. The season is late fall or early winter. [S1]
The tree is described simply as a heavy bearer. The cited entry gives no direct hardiness statement for S. D. Bona, but it was introduced in a South Dakota hardy fruit program aimed at northern plains conditions. Sources here do not show later descendants, and the surviving evidence is mainly a brief but vivid cultivar note rather than a full monograph. [S1]
