FARMER'S MASTER HYBRIDS for 1950 
*Master Hybrids are bred, produced, tested in Minnesota to insure fitness for Northern climates. Be- 
low we give you only FACTS. We quote yields from unbiased OFFICIAL STATE TRIALS, conducted by 
State Experiment Stations—not from private tests! (In Minn. State Tests, a plus index shows degree of 
superior performance over the average of recommended hybrids.) 
MASTER F-21 
For Zones A & B 
One of the best extra-early hybrids on 
the market and a great favorite in 
Northern Zones of Minnesota, North Dakota, Montana, 
Wisconsin and Michigan. Made 58.8 bushels per acre 
in 1948 North Dakota Trials, Cass County. This hybrid 
outperformed the average of all hybrids recommended 
for the Northern Zone of Minnesota by 72 onin: official 
trials. It was named the highest yielding of all hybrids 
tested in Official Michigan trials in the Northern Zones, 
and produced 90.6 bushels per acre in 1948 Official 
South Dakota Trials (Lawrence County). F-21 earned 
an exceptional Performance Score of 109.9* in Dewey 
County, South Dakota Trials. 
Peter Braaten, who farms near Ada, in Northwestern 
Minnesota, writes: ‘I like Master F-21 the best of all the 
corns that I've been able to purchase. My neighbors 
like it so well that I am ordering for them. It’s the 
easiest corn to pick of any I’ve ever grown.” 
Plant height 74 inches, ear height 29 inches, ear 
length 7 inches, 14 to 16 rows, no broken stalks. Easily 
harvested with mechanical picker. Produces bright, 
sound, deep yellow ears with golden bronze tinge. 
High feeding value. Performs well on peat or muck 
soils. Popular for hogging off in Southern Zones.

MASTER F-31 
For Zones C & D 
The feature of this hybrid is its ex- 
tremely high shelling percentage of 
86.6%. It gives strong germinating, vigorous, early 
growth which gets it ahead of weeds in the event of a 
cold, wet spring. It responds well to a thick rate of 
planting for maximum yields. The deep roots make 
good wind resistance on this hybrid and ears are borne 
at a convenient height for harvesting. 
The tips of the ears are characteristically well filled, 
a feature common .in drought resistant corns. Ears are 
typically about 7% inches long with medium dent like 
Minn. No. 13. The kernels have plump tips and a high 
test weight per bushel, often as high as 60. lbs. This 
hybrid dents rapidly in the fall and dries quickly to 
permit safe early cribbing. Produced 57.9 bushels per 
acre in our trials, with plant height of 85 inches, ear 
height 30 inches, 8 inch ears have 12 to 16 rows. 

MASTER F-32 
For Zones C & D 
The outstanding feature of this new 
Master Hybrid is its high rating for 
cold resistance, permitting it to germinate and grow 
well during cold, wet springs in the North Central Zone 
of Minnesota and similar areas. 
Sturdy, medium tall stalks carry attractive, well- 
shaped, drooping 7 inch ears with 12-16 rows of deep 
kernels on a small cob. It's reasonably easy to husk, 
and picks well with mechanical picker. 3 year aver- 
age yields in our trials: 54.82 bu. per acre, plant height 
77 inches, eqr height 29 inches, ear length 7 inches, 
husk—loose to medium.

MASTER F-41 
For Zones D & E 
A yellow dent hybrid producing a 
chunky ear of medium length that is 
heavy and sound in quality, and harvests easily with 
mechanical picker. It’s tailor-made for Minnesota’s 
North Central Zone and similar areas of Wisconsin, 
Michigan, North and South Dakota. In Fargo, North 
Dakota trials, it was given a relative maturity rating 
of 91 to 95 days with good field appearance and a 
medium-short shank. In South Dakota Trials, it re- 
ceived the extremely high Performance Score of 112.9* 
(Hyde County 1948). In Michigan Trials (Montcalm 
County), it produced 61.5 bu. per ‘acre. 
As an indication of its wide adaptation, Samuel 
Atchison of Syracuse, New York writes: ‘I had Master 
F-41, and despite the long dry spell, it came through 
great. I had the best field of corn in Ocondage County.” 
Four year averages show plant height 87 inches, ear 
height 32 inches, no broken stalks, ear length 8 inches, 
and 16 rows. An excellent feeding corn. Performs well 
on peat soils, ideal for hogging off in more southern 
sections. y

MASTER F-60A 
For Zones D, E & F 
This hybrid stands out among all 
others of similar maturity, in field ap- 
pearance, with its broad, deep green leaves, its long, 
show-type ears, packed with deep; bright yellow ker- 
nels. It stands out in performance, too. In North Dakota 
trials (Richland County), it earned a relative maturity 
rating of 95 to 99 days and showed strong resistance 
to lodging. In 1948 South Dakota trials (Brown County), 
it won a Performance Score of 105.4*, and in 1948 
Michigan trials (Saginaw County), it produced 73.6 
bushels per acre. Produced 93.1 bushels per acre in 
our Southern Minnesota Trials, outyielding all others 
in its maturity class. 
It’s adapted to Central Zones of Minnesota and simi- 
lar areas in Wisconsin, Michigan, South Dakota, as 
well as Southeastern North Dakota. Tests show plant 
height 88 inches, ear height 36 inches, ear length 8 
inches, 16 to 20 rows, free of ear rots-with deep kernels 
of highest feeding value. It harvests well mechanic- 
ally, and has proved excellent for silo filling in 
Northern Zones. 
Many customers are so enthusiastic over F-60A that 
they take the trouble to write about it. George Gotz of 
Auburndale, Wisconsin writes: ‘'My field of F-60A was 
the envy of the neighborhood last year, so I’m now 
ordering for several of my neighbors.’’ Fred. Guetzkow 
of New Germany, Minnesota writes: ‘Your Master 
F-60A matured early: and for the dry summer we had, 
it surely was good in spite of our light soil. We had 
wonderful results, and are more than satisfied.’ Henry 
A. Braun of Rosholt, South Dakota writes: ‘I have one 
of the nicest fields of corn in the neighborhood. It’s 
F-60A, and if nothing happens to it, it will be the 
biggest corn crop I’ve ever raised.”

MASTER F-82 
For Zones E & F 
Here’s the “‘old favorite’ of the Master 
Hybrids. It can't be replaced in our 
plant breeding program because so many farmers de- 
mand it year after year. They feel it can’t be beat for 
yield of dry shelled corn, standability, and resistance 
to root lodging. Its small cob with deep, thick kernels 
yields 86.1% shelled corn. F-82 earned a relative ma- 
turity rating of 103 to 107 days in North Dakota Trials, 
as well as the following comments: good field appear- 
ance, very good ear appearance, short shank, medium 
tight husk. In 1948 South Dakota Trials (Brookings 
County), it produced 81.6 bu. per acre, and in 1948 
Michigan Trials (Ingham County), it yielded 77.8 bu. 
per acre with a Performance Score of 104.08*. 
Four year averages show: plant height 96 inches, 
ear height 42 inches, no broken stalks, ear length 8 
inches, 16 rows. Harvests easily, mechanically. A 
favorite with our customers everywhere in the 105 day 
Soe. An excellent silo corn in Northern and Central 
ones.

MASTER F-83 
For Zones F & G 
Surprisingly heavy yields are _ har- 
vested from this brand new hybrid, 
bred as a full season hybrid for Minnesota’s South Cen- 
tral Zone and similar areas, where the season is just 
alittle short for our famous Master F-101A. New F-83 is 
characterized by its heavy, dark green foliage, deep 
kernelled, heavy ears, 8 to 9 inches long, extra strong 
stalks and root systems. Its yielding power has been 
proved in six trials, planted and farmed on average 
farms of variable soil types, with standard farm meth- 
ods. The result: an average yield of 91.34 bushels per 
acre was harvested! Since this hybrid is brand new, 
no Official State Yield Trial results are available as 
yet. In the farm tests this hybrid grew to a height of 
97 inches, and bore ears at 42 inches. For the corn 
grower who feels that Master F-101A is just a little too 
late for his land, here is a hybrid to be proud of, in 
the field—and in the bin after harvest—it's tailor-made! 

Ff. 8. & N. Co. December, 1949 
This year your Master F-21 averaged better than 
60 bushels per acre on our farm. We are all well 
pleased because this is considered a very good crop 
here in Northern Minnesota. Ever sinee-we first 
tried them several years ago, we have used none 
other than your Master Hybrids.
