NORTHEiJ.'^ PLANT NuVELTIES FOR 1940 - - 
Department of Horticulture, Si^uth Dakota Experiment Station 
Brookings, South Dakota, January ].8, 1940 
Total Nine Pages 
This department does not conduct a commercial nursery, but propagates and 
distributes new varieties originated in this department or imported from similar cli¬ 
mates of the Old World. Many acres of seedling fruits have been grown since the 
work was started in 1895• The improvement in siae and quality of each plant gener¬ 
ation is greater year by year. Hybridistation and selection are the main methods of 
improvement. The work has been honored by four medals awarded to Dr. N. E. Hansen 
and by extensive propagation and planting of many of the new varieties. The medals 
are: The George Robert White gold medal of honor for "eminent service in horti¬ 
culture" by the Massachusetts Horticultural Society, 1917j the Marshall P. Wilder 
silver medal by the American Pomological Society for nev/ fruits, 1929; gold medal 
for public service by Cosmopolitan club, Sioux Falls, 1933J A. P. Stevenson gold 
medal for new fruits by the Manitoba Horticultural Society, 1935» 
A host of new seedling fruits and roses is coming on, which will be sent 
out as soon as they are deemed to be up to standard. 
Some of the material in this list is offered for distribution to plant- 
breeders to help in the work of iraproving hardy fruits and roses elsewhere. 
Terms : The money received from the sale of plants makes it possible to do 
the work on a larger scale than would otherwise be possible. Those who have followed 
the progress of the v/ork for many years know the importance of ordering promptly, as 
soon as this list is received, as the supply of plants is limited. Terms are cash 
with order. No credit except to the Government Experiment Stations. For South Dakota 
orders add three per cent to the above prices for State Retail Sales Tax. 
Northern Novelties in Fruits and Roses 
The following new introductions by Dr. N. E. Hansen, Emeritus Professor of 
Horticulture, are v/orthy additions to his long list of hardy fruits and roses, (Nine 
varieties are offered for the first time): 
Pear Okolo, Sungari, Ilya. 
Crabapple -Keo. 
Apple -Nebo, Semla. 
Bushcherry-Checkpa, Kasota. 
Rose-Yawa. 
NOTE : There are no propagation restrictions on any of these nev/ varieties. 
Fruits Already Introduced; Scions of new fruits listed in earlier lists 
will be supplied as far as available at 50 cents per foot. 
Progress in Pears 
It has been the endeavor for many years to hybridize the native pear of 
East Siberia and North China with standard cultivated pears. Several have already 
been named. It is gratifying to report splendid progress in 1939 with hybridizing 
pears. Several new seedlings bore a heavy crop of fruit, excellent in quality and 
of good commercial size. The trees are free from fire-blight. Some of them will be 
named for distribution next spring. This work ajrpiy demonstrates that the size and 
high quality of the standard pears of western Evirope can be combined in large 
measui’e with hardiness and imm-unity to fire-blight of the pears of East Siberia and 
north China. 
Okolo pear - Offered for the first time. Pedigree; a seedling of Pyrus 
Qvoidea (Simonii) . Fruit 2^ x 2^ inches, obtuse pyriform. Clear light yellow, v/ith
