Orel No 20 is listed as a domestica plum of Russian origin. In South Dakota trial literature, it appears as a long tested but marginal orchard plum, not a recommended commercial sort. The old Station orchard, planted in 1888, still had two trees in fair condition, but both had many dead branches. This suggests limited hardiness or accumulated winter injury under local conditions. [S1]
The same source describes Orel No 20 as a shy bearer and rejects it for commercial planting on that basis. [S1] The cited entry gives no fruit description, season, flavor, or culinary use. Its historical interest here is mainly as part of the Russian Prunus domestica material tried on the northern plains and found unproductive. [S1]
