CORN HYBRIDS AND CROSSES 
This is corn produced from tested crosses either of inbreds 
of a single variety or of selected stocks of two greatly dif¬ 
ferent varieties. Hybrid vigor has long been recognized as 
a result of crossing in cattle and has of late years been dem¬ 
onstrated to be a result also of crossing breeds of hogs, poul¬ 
try and corn. Hybrid com usually is more vigorous, more 
disease resistant and much more productive than the common 
or open pollinated varieties. To produce a hybrid of any va¬ 
riety pure inbreds are first isolated by self pollinating for 3 
to 5 years. Those giving best results to the number of 2 to 4 
strains are grown to use in producing the desired hybrid and 
to carry on the pure strain from year to year. Hybrid seed 
corn must be the product of a fresh crossing each year to be 
of any value. 
Sometimes it is found that two regular open pollinated va¬ 
rieties which differ widely in type from each other will also 
show great hybrid vigor and improvement in production. 
Such hybrids are called variety crosses. 
Hybrid corn is sold in sealed bags of 1 bu. size or less

There are a few hybrids from Minnesota which show some value. 
There are two or three hybrids from the North Dakota Station 
which show promise for North Dakota. We, ourselves, have offered 
a Northwestern Dent Hybrid but lost one inbred and shall discon¬ 
tinue it till another suitable inbred is tested out. We offer also a 
Hybrid Falconer which seems to have some good Hybrid qualities 
for North Dakota. 
EARLY MINN. 13 HYBRID

in Minnesota, we offer this hybrid after a careful test on our own 
trial plots. Lb., 50e, postpaid. F, O. B. here: 10 lbs., $1.50; y 2 bu., 
$4.00; bu., $7.50. 
N. D. A. C. DAKOTA FLINT HYBRID

FAL C ONER HY¬ 
BRID. A hybrid 
from four inbred 
strains selected 
by us some eight 
years ago. Has 
v given us less 
smut, sturdier stalks and heavier yield. Lb., 40 c, postpaid.

VARIETY CROSSES 
Some years ago it was determined in Minnesota that 
variety crosses of very different types of corn would 
produce hybrid vigor equal to that of most regular hy¬ 
brids. Furthermore it was determined that a flour corn 
crossed with a dent was practically sure to give a much 
increased yield. Along that line we have experimented 
for the past several years and we can announce with 
certainty that we have to offer this year several variety 
crosses which will give to our customers most of the 
advantages of .hybrid corn. They were produced by 
crossing several flour corns and Falconer in different 
fields with Dents, always using the Dent as male parent. 
FALCONER x ALTA. Offered last year and has given excellent results. A taller corn and more dent¬ 
like than Falconer with very good yields. Pollenizing Falconer silks with Alta pollen produces this 
cross. Lb., postpaid, 50c. F. O. B. here: 10 lbs., $1.00; x / 2 bu., $3.00; bu., $5.00. 
PRIDE OF THE PLAINS FLOUR x PIONEER WHITE DENT, if this cross behaves as in earlier trials 
and in accordance with Minnesota results it should give a very heavy yield. White Dent pollen used 
on the flour corn silk. Postpaid, lb., 50 c; 10 lbs., $1.25; % bu., $3.25; bu., $6.00. 
MANDAN-NAV A J O YELLOW FLOUR x ALTA. Another flour corn crossed with Alta Dent which should 
give a very vig¬ 
orous and high 
yielding product 
of good height. 
Postpaid, lb.,50c. 
F. O. B. here: 10 
lbs., $1.25; *4 bu., 
$3.25; bu., $6.00. 
NAVAJO SACRED 
FLOUR x ALTA. 
Silks of the Cu- 
d e i or Sacred 
Navajo Flour 
Corn pollenized 
from Alta tas¬ 
sels. Our sup- 
p 1 y of this is 
very limited as 
it was our first 
experiment with 
these two va¬ 
rieties. Postpaid, 
lb., 50c. F. O. B. 
here: 10 lbs., 
$1.50; y 2 bu., 
$3.75; bu., $7.00.
