description Of Each Variety 
Pioneer 355 . . . 
AVAILABLE IN QUANTITY 
In the 1938 Minnesota Corn Periormance Test, this hybrid out- 
yielded Murdock open-pollinated com by 16.1 bushels per acre; 
it also outyielded the average hybrid by 4.2 bushels per acre 
in the same test, and it contained less moisture than both; in the 
Grant County field of the 1938 South Dakota Com Yield Test, it 
outyielded the average of open-pollinated com by 13.9 bushels per 
acre and contained the same amount of moisture; it is suitable 
for a wide range of soil types, being particularly satisfactory on 
alkali and peat soils; well liked by farmers who seal, and by those 
who shell and sell; adapted for hand picking; strong roots and 
stiff stalks; excellent ear dropping resistance; good drought resist¬ 
ance; may be susceptible to smut in dry years; low ear height; 
average size ears with medium dented kernels; short husks and 
long shanks. 
Pioneer 357 . . . 
AVAILABLE IN QUANTITY 
This hybrid matures about three days later than Pioneer 355, and 
ripens in Region B well ahead of the average first freeze; has high 
yielding ability for early corn; yielded 9.7 bushels per acre more 
than Murdock open-pollinated com in 1938 Minnesota Com Per¬ 
iormance Test and contained about the same amount of moisture 
as Murdock; good quality ears that shell out well; good feeding 
com; leafy plants; adapted for both machine and hand picking; 
seems to do particularly well on rich soil; suckers on high nitrogen 
content soil; excellent resistance to smut and ear dropping; good 
drought resistance; fair lodging resistance; moderately rough ears 
with long husks; medium ear height; short shanks. 
Pioneer 352 . . . 
AVAILABLE IN LIMITED QUANTITY 
A hybrid which combines outstanding yield and early maturity; 
ripens ahead of average first freeze in normal weather and over¬ 
age soil conditions in Region B; adopted for both hand and me¬ 
chanical picking; excellent resistance to smut and drought; strong 
roots and stiff stalks; fair resistance to ear dropping; large, wide 
groined ears with medium dented kernels and long husks; medium 
ear height. 
Pioneer 322 . . . 
AVAILABLE IN QUANTITY 
General purpose variety; very high yield record; has highest yield 
among all regular hybrid entries with 2 and 3 year averages in 
Northern Section of Iowa Corn Yield Test; adapted for wide range 
of soils; excellent for both hand and mechanical picking; good 
feeding corn; small cobs and deep kernels; good silage corn; 
exceptionally strong roots and very stiff stalks; excellent resistance 
to smut, drought, and ear dropping; medium size, moderately 
rough ears with long husks; medium ear height; should be planted 
early on average to high fertility soil in Region B. 
Pioneer 324 . . . 
AVAILABLE IN LIMITED QUANTITY 
High yielding, good feeding corn; excellent for machine picker and 
hand husking; very strong roots and exceptionally stiff stalks; 
medium ear height; good resistance to smut, drought, and ear 
dropping; medium size, moderately rough ears with long husks; 
same maturity as Pioneer 322, 
Pioneer 335 . . . 
AVAILABLE IN LIMITED QUANTITY 
Short stalked, leafy plants with low hanging ears; high yielding 
hybrid; yielded 8.2 bushels more corn per acre than the average 
of open-pollinated com in the Minnehaha County field of 1938 
South Dakota Corn Yield Test; fast drying com that shells out well; 
very strong roots and unusually stiff stalks; long ears with husks 
of medium length; medium dented kernels; good resistance to 
drought and ear dropping; may show a weakness for smut in dry 
years; maturity about same as Pioneer 322. 
Pioneer 349 . . . 
AVAILABLE IN LIMITED QUANTITY 
Exceptionally high yielding hybrid; won Banner Trophy and was 
the highest yielding hybrid in Northern Section of 1938 Iowa Com 
Yield Test; leafy plants; recommended for silage; excellent ear 
dropping resistance; very strong roots and stiff stalks; good 
resistance against droughts; may be susceptible to smut in dry 
years; large, moderately rough, deep kernel ears; ear height obove 
average; short husks; in Region B, it may be late in short seasons 
and should be planted early on fast or high fertility soil. 
Pioneer 315 . . . 
AVAILABLE IN LIMITED QUANTITY 
High yielding, good hand picking com; shells out well; seems to 
do particularly well on thin soil; smooth, average size ears; 
medium ear height; husks are medium long; fair resistance to root 
and stalk lodging; adapted for Region C. 
Pioneer 330 . . . 
AVAILABLE IN LIMITED QUANTITY 
Extremely uniform, rough eared hybrid; high yielding ability; ex¬ 
ceptionally strong roots throughout season, and very stiff stalks in 
the fall; may "stalk break" in mid-season; excellent smut resist¬ 
ance; large, deep grained, low hanging ears with long husks; good 
drought and ear dropping resistance; especially well adapted for 
hand and mechanical picking; good feeding corn; recommended 
for Region D on rich or fast soils. 
Pioneer 314 .. . 
AVAILABLE IN QUANTITY 
Large eared variety; quick drying, high yielding hybrid; good feed¬ 
ing corn; high shelling percentage; satisfactory for both hand and 
machine picking; medium dented kernels; excellent ear dropping 
resistance; strong roots and stiff stalks; susceptible to leaf smut, 
but resistant to ear smut; good drought resistance; medium ear 
height and medium length husks; must be planted on rich or fast 
soil in Region D.
