DIBBLE’S DOUBLE CROSS HYBRID 29-3 CORN 
T HE development of hybrid Corn during the 
past few years is one of the outstanding achieve¬ 
ments 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 Sweepstakes or Learning 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-if-you-want-it guarantee. 
HISTORY OF HYBRID 29-3 
Hybrid 29-3 is a double-crossed hybrid 
Corn developed at the Cornell Agricultural 
Experimental Station by inbreeding and cross¬ 
ing. Hundreds of inbred strains were de¬ 
veloped and crossed until hybrids of great 
vigor were produced. Then by crossing these 
hybrids a still more vigorous and better-yield¬ 
ing 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 field.
