Plant tlybrid Corn 

ADAPTED HYBRID SEED CORN 
SHOULD BE PLANTED 
WHAT IS HYBRID CORN? 
Hybrid Corn is not just another variety, it is the result of cross- 
ing or combining two or more self-fertilized or inbred lines. It 
is not made by merely crossing one variety with another. 
ADVANTAGES OF HYBRID CORN 
Larger Yields of Both Grain and Fodder: 10 to 20 bushels more 
CORN and 50 per cent greater tonnage of ensilage per acre 
have been obtained. Results are conclusive from proven data 
compiled after years of careful and exhaustive research by vari- 
ous State Experiment Stations, and the United States Department 
of Agriculture. 
Uniform growth and maturity of the better HYBRID strains 
are largely responsible for the increase in yields. There are 
practically no nubbins and very few barren plants. Uniformity of 
stalk height combined with evenness of ear ripening, and practi- 
cally identical position of ears on the stalks materially lightens 
the husking operation. 
Resistance to Lodging. Hybrids stand up where open-pollinated 
corn would lodge. This persistent, upright growth due to greater 
strength in both root and stalk permits the use of corn pickers 
through late Fall. The partially green fodder can be more readily 
used for feed. 
Resistance to Disease. Hybrids are decidedly more resistant 
to smut and root, stalk and ear-rot diseases than open-pollinated 
varieties. 
Resistance to Drought. The more unfavorable the growing con- 
ditions, the more striking is the advantage of hybrids. Under 
these conditions the greater vigor and vitality of hybrids become 
more apparent. 
During extreme heat and drought, the deep and extensive roots 
make hybrids drought resisting. This immense root system pro- 
vides a more than adequate anchor during heavy wind storms, 
keeping hybrid corn upright where open-pollinated corn would 
be flattened. 
The drought resistance of hybrids, and consequent yields, far 
in excess of open-pollinated varieties was clearly demonstrated 
in the dry season of 1934, 1936 and 1937. 
Better Feeding Value. If adapted strains of the better hybrids 
are grown, the soft corn problem is solved. With the elimination 
of soft corn and subsequent spoilage, the increased value of 
Hybrid strains from a feeding standpoint becomes apparent.

PLANT ONLY ADAPTED HYBRIDS 
PRIDE B17—(90-95 day maturity) 
This all-yellow Hybrid Corn is 5 to 7 days earlier than Standard 
strains of Minnesota 13. It is recommended for the higher alti- 
tudes in northern Colorado and Wyoming and for late planting 
in more favored sections. Very uniform in appearance, stiff stalked 
with deep disease-resistant root system. 
TRU-KROST MINHYBRID 301—{105 day maturity) 
This all-yellow Hybrid originally developed by the Minnesota 
Experiment Station was perhaps the first Hybrid to receive general 
acceptance in Northern Colorado. It is still favored by many 
farmers in this section for its ability to yield under adverse condi- 
tions. Recommended for early planting in Denver area, Fort 
Collins and similar, and late planting in Julesburg, Yuma and 
Wray Districts. 
TRU-KROST MINHYBRID NO. 403—(107 day maturity) 
This Hybrid is another introduction of the Minnesota Experiment 
Station and has shown up well in the Colorado state trials. It has 
proved popular with farmers generally throughout Northern Coilo- 
trado because of the high tonnage of fodder it produces together 
with substantial yield of yellow corn of good feeding and market 
quality. Recommended for early to regular planting in Denver 
area, Fort Collins, northern New Mexico and late planting in 
Julesburg, Yuma and Wray Districts. 
PRIDE C-53, D-56, B58—(107-110 day maturity) 
All-yellow Hybrids which represent our plant breeder’s im- 
provement on old Minhybrid 301. Perhaps two or three days 
later, stiffer stalked and somewhat leafier than 301 and in our 
own trials have shown yield advantages of five bushels or more 
to the acre. Recommended for early to regular planting in Denver 
area and Fort Collins. 
WISCONSIN 570 (COLO 151)—(110 day maturity) 
This is a dual-purpose hybrid originally developed by the Wis- 
consin Experiment Station. It is capable of producing high yields 
of fodder and grain. Jt produces showy ears, well filled to the 
tip with dented yellow kernels. Stalks are strong and wind- 
resistant. A valuable replacement for Reid's Yellow Dent. The 
Colorado development is known as Colo 15]. 
TRU-KROST WISCONSIN 606—(110 day maturity) 
A development of the Wisconsin Experiment Station. Very 
similar in plant and ear type to Wis. 570. Produces a leafy 
growth. Stalks are resistant to lodging, short shank, closely 
packed kernels. Recommended for Denver area and localities 
with similar conditions.
