Out Earli^nTonLate Series 
To get the most enjoyment and profit out of sweet corn, home 
gardeners, roadside stand gardeners and some market gardeners 
should plant hybrids that will provide a continuous harvest, from the 
earliest possible to the last of the season. Canners find it better to 
include hybrids that are earlier than the main crop, in order to 
lengthen the harvesting period and lessen weather risks. For some 
markets only the earliest possible corns pay well; for others the 
latest; and for some there are in-between periods when prices are 
usually highest. Our series of hybrids, ripening at intervals, helps 
you plant to meet your market requirements. Our offerings and 
recommendations are based on careful study of numerous sweet corn 
trials all over the Country and reports from our customers, as well 
as our own experience. We believe we are offering the best and most 
profitable hybrids available in their respective periods of ripening. 
PLANTING SUGGESTIONS 
Early market prices usually are highest. To make the most of 
them we suggest one or two small successive plantings of Cockcrow 
before weather conditions are quite safe. Select early ground. Use 
our treated seed. Do not plant too deeply. Then when conditions 
are safe, plant at one time all the Cockcrow and Spancross you can 
pick and sell in 6 to 10 days. If any of the first plantings is lost, 
IDhq Are Hqbrid Sweet Corns 
Used More and More? 
The explanation is simple. Compared with old varieties of 
equal earliness, the leading hybrids yield 25% to 100% more; they 
are much more uniform in ripening and in size and type of ear; and 
they equal or excel in sweetness and tenderness. They have other 
advantages, too. Hybrid vigor enables them to better endure drouth 
and resist root rot. Some of the hybrids show marked resistance to 
Stewart’s Bacterial Wilt Disease, which caused such heavy losses in 
’33 and which may occur again. Vigor also enables them to retain 
satisfactory eating quality several days longer after ripening than 
other sweet corns. Their greater uniformity means fewer pickings, 
often only one and a larger percentage of marketable ears harvested. 
It means fewer immature or overripe ears and more perfect ears. 
For marketing or canning, this uniformity is very valuable. 
Scores of tests by experiment stations, seedsmen, canners and 
gardeners have proved these facts. In brief, the better hybrids pay 
better, a lot better—^^in fact, so much better that careful growers 
who have used them would not plant the old kinds again, even if the 
seed were furnished free. 
The above statements are true of the leading hybrids but not 
of all the hybrids on the market today. The wonderful performance 
of several of the first hybrids put out, led to the introduction of 
.scores of other hybrids, many of which are very little better than 
the old varieties. So in choosing sweet com hybrids today, it is im¬ 
portant to know the performance recoids. 
replant with any yellow sweet corn or other crop. One of these 
plantings on the market ahead of the crowd will more than repay the 
labor and seed lost on several. 
For a continuous supply, make at least one planting of Cock¬ 
crow a few days before the safe date. Then, when it is safe, plant 
at one time equal areas with seed from each of these three groups: 
(1) Cockcrow; (2) Spancross, Whipcross C6.2, Suncross; (3) Chari- 
cross, Hybrid 0 K, Hybrid X L, Golden Cross. Each area should 
be what you want to pick and sell in a 6 to 8 day period. Then at 
weekly intervals plant additional areas of Hybrid X L or Golden 
Cross, up to 80 days from your fall freezing date. This will give as 
continuous a supply as can be arranged, of quality corn that will 
vdn and hold your customers. 
If your late markets are extra good, make several plantings 
of Hybrid X L or Golden Cross 100 to 80 days before the fall freezing 
date or 2nd plantings of Cockcrow, or Spancross 80 to 60 days be¬ 
fore that date. 
Because hybrids are such vigorous growers, they must have 
normal or greater spacing. If your stand is too thick, be sure to 
thin it. 
How Are Hqbrid Sweel Corns 
Produced? 
Recently plant breeders learned that by artificially inbreeding 
strains of corn for some years, then crossing them by controlled pol¬ 
lination, they usually get in the first crop remarkable “hybrid vigor” 
and also always the same definite and uniform characteristics. After 
producing hundreds of inbred strains and crossing them in thousands 
of different combinations, breeders have succeeded in finding com¬ 
binations that produce vigorous hybrids that are mighty near per¬ 
fection in other characters as well. 
The controlled crossing of two different corns is accomplished 
by planting one row of the pollen parent to every two to four rows 
of the seed parent. Every plant in the seed rows is kept detasselled 
thruout the season so that their ears are fertilized by the pollen 
parent. The two parent strains have to be maintained separately, 
and kept strictly self fertilized. Timeliness, thoroughness and ever¬ 
lasting watchfulness are absolutely essential. 
Quaker Hill Farm was one of the first in the Country to pro¬ 
duce commercially by cross pollination these new hybrid sweet corns. 
We have gained the experience, acquired the technique, trained the 
help and provided the equipment for producing reliable hybrid seed. 
Our sweet corn seed goes into neai'ly every State and into Canada.
