CHIPPEWA 
The heavy yielding 
midseason potato 

Chippewa. 
A midseason or second early potato recently introduced by the U. S. 
Department of Agriculture which in trials has proven outstanding for the 
northern states. It is resistant to mild mosaic and a heavy yielder. The 
Grand Rapids Station reports a yield of 464 bushels to the test plot. 
Mr. R. L. Donovan of the Grand Rapids Station states that Chippewa 
will replace the old standard varieties and outyield them by a large 
margin. We recommend it to Wisconsin potato growers as it is earlier 
than Green Mountain and other late potatoes and is a handsome potato 
and a heavy yielder. The skin is velvety white, has shallow eyes and 
is oblong in shape. Since we first introduced this new potato, our sales 
have greatly increased each year. It is probably the heaviest yielding 
potato on our list. Seldom has hollow hearts and always cooks up white.

Grading Katahdins. 
KATAHDIN 
P New Heavy Yielding Late Storage Potato 
Katahdin is one of the new higher yielding late varieties, which is 
generally adapted to Wisconsin growing conditions. It was developed 
by the U. S. Dept. of Agriculture at Presque Isle, Maine. It is a 
- heavy yielder, resistant to mild mosaic, tolerant to heat and drought con- 
ditions, but extremely susceptible to scab. On _ scab-free soils it pro- 
duces beautiful white tubers of high market quality. The potatoes are 
very similar in shape and appearance to Chippewa. ‘The skin is 
velvety white, very shallow eyes, oblong and somewhat flat in shape. 
On light soils the tubers have a tendency to come up through the soil 
and sunseald. The vines seem quite resistante to Hopperburn. The best 
Keeping variety on our entire list.

LATE OR MAIN 
CROP VARIETIES 

Blight Resistant Sebago. 
SEBAGO 
Late Blight Resistant Potato 
A late potato introduced and released in 1937 by the 
States Department of Agriculture at the Potato Breeding 
Presque Isle, Maine, from a cross between Chippewa and Katahdin. Dur- 
ing a period of about five years, prior to its introduction, it exhibited 
remarkable resistance to late blight tuber rot caused by one of the 
most serious Potato diseases, known as Phytophthora Infestans which 
was the disease that caused the crop famine in Ireland in 1845. 
From 19388 to 1941, the Wisconsin College of Agriculture carried on 
extensive tests in nine different Potato-producing counties. These years 
the blight was unusually severe, but Sebago showed only 5% Blight 
United 
Station aft 
Tuber Rot whereas the other standard sorts showed as high as 75 to 
85% tuber rot. Recent tests also show that this variety is highly 
tolerant to Potato Hopperburn caused by the Potato Leaf Hopper. Wis- 
consin College of Agriculture Potato Specialists have found the Sebago 
is definitely resistant to the Yellow Dwarf disease which often causes 
heavy losses in the sandy soil regions of Wisconsin, Michigan and Min- 
nesota. Its yielding ability is about the same as Russet Rural or Cobbler. 
Cooking tests show the variety to cook up white where under the same 
conditions standard varieties cooked black, 
The tubers are very similar to Chippewa—white, thin skinned, shallow- 
eyed, and oval to oblong in shape. Vines are large, definitely upright 
in growth habits. During hot weather it has a tendency to roll .its 
leaves which cause it to resemble the Leaf Roll Disease. This, however, 
has no connection with the disease. In season it is definitely a late 
potato. It sets its tubers several weeks earlier than Rurals, but the vines 
remain green just as long and sometimes longer. Because of its fine 
quality and thin skin, it is quite susceptible to Scab. Plants set heavy 
with tubers and therefore it requires a fertile soil.

Russet Rural. 
RUSSET RURAL 
size and yield, the Russet Rural is very similar to the 
White Rural New Yorker, the only difference is that the skin is slightly 
russet and tubers in shape are more flat and a trifle shorter. Growers 
claim that the Russet has a little better quality than the W hite, and are 
more popular on some markets. An old variety that is losing its popu- 
larity rapidly to the new Chippewa and Blight Resistant Sebago varieties. 
Resistant to Hopperburn. Like the W hite Rural it sometimes cooks up 
dark. The shallow eyes and attractive appearance make it popular on 
the market, but it is largely grown because it yields heavily and is quite 
resistant to scab. - :
