Varieties which failed in the above test include Hungarian, Dakota, 
Monitor, Suelter, Beta, Janesville, Moore, Worden, Concord, Camp- 
bell, Niagara, Delaware, Agawam, Clinton, Elvira, Martha, Brighton, 
Lindley, ‘‘Robert’s Wild White,’ Alvado, Bacchus, Berckmanns, 
Elvibach, Etta, Faith, Grein Golden, Missouri, Riesling, and Presley. 
The only partial success with grapes was obtained in the combina- 
tion fruit patch planted in 1918, where 5 vines each of Alpha, Beta, 
Hungarian, Monitor, ‘‘Robert’s Wild White,’ and Suelter were 
planted 8 feet from a row of plums on one side and 8 feet from a row 
of apples on the other. An addition of 5 Concord, 3 Beta, and 1 
Worden was made in 1919; and 6 vines of Beta in 1922. Of these, 
3 Alpha, 4 Beta (1918 planting), 5 Monitor, 4 “‘ Robert’s Wild White,” 
4 Suelter, 1 Concord, and 6 Beta (1920 planting) were alive in the 
fall of 1922. All of these varieties produced some fruit in 1922. 
- Concord is too late to be of value. The quality of the other varieties 
is poor, but better than the average native grape. 
Considering the many failures, it seems that none of the varieties 
tested can be recommended for general planting under dry-land 
conditions on the northern plains. 
CURRANTS 
Of all fruits tested at Mandan, currants are among the most 
reliable bearers. They are fairly drought-resistant, and generally 
hardy without winter protection. Nine varieties of red currants 
were under trial for the eight years 1915-1922. The yields varied 
from complete failures in some years to more than 344 quarts to the 
plant (for North Star) in 1918. Yields of more than 2 quarts to the 
plant were not uncommon in favorable years. London Market and 
North Star are the most prolific of the varieties tested. London 
Market is the most dependable, but North Star yields better in 
especially favorable years. The average yields of the varieties 
tested for the eight years are given in Table 12. 
Four varieties of black currants (Ribes nigrum), Naples, Victoria, 
Champion, and Lee, were grown for three years. None of these 
varieties yielded as heavily or bore as consistently as the best red 
varieties, and therefore their culture is not recommended. The 
Kuropean black currant (Ribes nigrum) is the most susceptible and 
dangerous host of white-pine blister rust and its propagation and . 
culture should be entirely abandoned. 
Varieties, such as Crandall, originated by selection from the 
native flowering currant (Ribes odoratum) do very well and are 
consistent bearers, even in dry years. Some promising selections 
have been made at the station and are being tested. It is likely 
that they will yield as well or better than the best red varieties.
