Red wing (Minnesota No. 12) (P. salicinaXP. americana)—Semihardy (2); 
large attractive fruit of good quality; midseason; heavy bearer. This is one of 
the finest fruits grown at the station, but there is some doubt of its hardiness. 
““ Richard” (P. nigra?) —Semihardy to hardy; good-sized, attractive fruit; mid- 
season; medium bearer; dwari habit. 
Sansoto (P. besseyiX P. americana) ——Semihardy to hardy; similar to Chere- 
soto. 
Sapa (P. besseyiXP. salicina)—Semihardy; small to medium-sized fruit 
of good quality, with dark-purple flesh and small pit; early, prolific; bears second 
year. This variety is one of the finest of the sand cherry—plum hybrids, is 
drought resistant, and generally a heavy bearer, although not as prolific as Opata. 
It is not as hardy as Opata, and this is its chief drawback. It has done best in 
bush form. 
“S. P. I. No. 36607” (Prunus sp.)—Hardy; small green or yellow fruit of 
very good quality; early; light to medium bearer. This little plum is worth 
planting on account of its hardiness and superior quality, and because its flavor 
is so decidedly different from other plums tested. Its disadvantages are early 
blooming and its tendency to light crops. It should be of value in breeding 
work. 
“Seedling No. 2” (P. americana)—Hardy; medium-sized, attractive, red, 
mottled fruit of fair to good quality; early; prolific bearer. This variety was 
propagated from a seedling orchard near Edgeley, N. Dak. It is an earlier, 
hardier, and better plum than most of the standard P. americana varieties and 
deserves wider testing in the area. 
“Seedling No. 5” (P. americana)—Hardy; medium-sized fruit of the De 
Soto type, but earlier and larger; prolific bearer. Obtained from the same 
source as Seedling No. 2 and is also worthy of distribution. It is one of the 
most valuable of the P. americana varieties tested. 
Stella (P. salicinaX P. americana) —Semihardy; large attractive fruit of fair 
to good quality; midseason to late; light bearer. 
Stoddard (P. americana) —Semihardy; large, fine, attractive fruit of fair to 
good quality; late; light bearer. Not recommended. 
Surprise (P. hortulana mineri)—Semihardy; medium-sized attractive fruit of 
good quality; late; light bearer. 
Terry (P. americana) —Young trees not hardy, having repeatedly winterkilled; 
older trees, semihardy; large attractive fruit of fair to good quality; midseason 
to late; prolific bearer. This is a fine plum, but it has been subject to considerable 
winterkilling at Mandan. ‘The few trees that have reached a bearing age seem 
to become hardier as they grow older and bear heavy crops of excellent fruit. 
Teton (P. americana) —Hardy; medium-sized to large attractive fruit of fair 
to good quality; late, prolific bearer. A good americana pium, but sometimes 
the fruit drops badly. Tree a vigorous grower. 
Tonka (Minnesota No. 21) (P. salicinaX P. americana.—Semihardy (?); large 
attractive fruit of good quality; midseason; medium bearer. A very good variety 
if it proves hardy enough to warrant general planting. 
“Training School Special” (P. americana?) —Apparently hardy; attractive red 
fruit of medium size and good quality; midseason to late; medium bearer. This 
plum was propagated from an old orchard on the grounds of the State training 
‘school. It may be some named variety or a root sprout, but is better than most 
standard americana varieties. 
Waneia (P. salicinaX P. americana) —Semihardy; large attractive fruit with 
firm flesh and good quality; midseason; prolific bearer. This variety is one of 
our finest plums, but there is some doubt whether it is hardy enough to warrant 
general planting on the northern Plains. 
Wolf (P. americana)—Semihardy to hardy; medium-sized attractive fruit 
of fair to good quality; midseason; medium bearer. One of the best of the 
standard americana varieties. 
Wyant. (P.~americana)—Semihardy to hardy; medium-sized, fair quality, 
almost freestone fruit; late; prolific bearer. This variety has been. a-.heavy 
annual bearer and is valuable for that reason. 
Many other varieties of plums are under trial, but as yet there are 
not sufficient data to warrant comment on them. Results indicate 
that the following list of plums, arranged in the order of ripening, 
would furnish a continuous supply of fresh fruit from the first of 
August to the middle of September: Opata, Cree or Oziya, Sapa, 
Compass, “Seedling No. 5” or “Seedling No. 2,” “S. P. I. No.
