DIBBLE'S 
HYBRID 
29-3 
HE development of hybrid Corn during the past few years 
is one of the outstanding achievements in agricultural 
progress. The leading states in the Corn Belt planted over 
three quarters of their acreage to hybrid Corn in 1940. 
In Dibble’s Hybrid 29-3 we now have a hybrid Corn that is 
adapted to our eastern conditions. It matures in about 110 to 
115 days and has the widest adaptability of any Corn grown in 
the northeastern territory. The ear is 9 to 10 inches long and 2 
inches in diameter, tapering slightly. It is yellow Corn with a 
slightly reddish tinge and showing deep amber between the rows. 
A very distinct-appearing Corn. 
We recommend it for ensilage wherever West Branch Sweep- 
stakes or Leaming is now used, and for grain wherever Golden 
Glow or a late strain of Cornell 11 matures. Comparative tests 
show it produces 40 to 50 per cent more grain at silage-cutting 
time and 15 to 20 bushels more of dry shelled grain per acre at 
husking-time. 
Our seed is from carefully selected, hand-picked ears, thoroughly 
recleaned, of splendid germination, and we sell it subject to your 
test on our money-back-it-you-want-it guarantee.

Double Cross 
CORN 
HISTORY 
of Hybrid 29-3 
Hybrid 29-3 is a double-cross hybrid 
Corn developed at the Cornell Agricultural 
Experiment Station by imbreeding and 
crossing. Hundreds of inbred strains were 
developed and crossed until hybrids of 
great vigor were produced. Then by cross- 
ing these hybrids a still more vigorous 
and better-yielding Corn resulted. The 
double-crossed hybrid was called Hybrid 
29-3. The varieties used in making this 
double cross are inbred strains of Luce’s 
Favorite, Onondaga White Dent, Cornell 
11, and Bloody Butcher. 
The work of producing the inbred strains 
and of making the single crosses from those 
strains is done by our experimental station 
at Cornell. The second or 
final cross we do on our own 
farms. 
Each year seed must be 
produced by this same careful 
procedure because no hybrid 
Corn will reproduce its own 
kind from seed. New seed 
must be obtained each year 
from growers who specialize in 
this fteld. 
When the white-oak leaves are as big as a 
squirrel’s ear, then it is time to plant corn. 
—Old Indian saying. 
DIBBLE’S 
Northern-grown SEED CORN 
The utmost care is taken to furnish Seed 
Corn of the highest possible quality, Corn 
that is thoroughly dried naturally or dried 
artificially by the most up-to-date methods 
known, of high germination and of varieties 
that are adapted to the northern and 
eastern states. 
Northern-grown Corn is the only kind 
to plant in the northern states. It is vigor- 
ous, hardy, acclimated, and productive. 
Southern-grown varieties look nice, ger- 
minate well, but do not mature.
