DOUBLE CROSS 
HYBRID 29-3 
The 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 one-half of their acreage to hybrid Corn in 1938. 
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 
See page 8 for Winners of 
Photographic Contest 
Hybrid 29-3 is a double-crossed hybrid Corn developed at the Cornell Agricultural Experimental Station 
by inbreeding and crossing. Hundreds of inbred strains were developed and crossed until hybrids of great 
vigor were produced. Then by crossing 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 re¬ 
produce its own kind from seed. New seed must 
be obtained each year from growers who spe¬ 
cialize in this field.
