5. Give special attention to a part of the field so that a uniform
stand may be obtained.
Select enough seed from this part of the
field for the entire acreage. Select seed for the following year's
seed plot in the fall before a killing frost, from perfect stand
hills and from those stalks which appear free from disease and
which under competition show ability to produce one or
more good ears. Throw away only the ears of very undesirable
type.
6. Continue the method outlined under 5 for a period of four
or five years and then use again the ear-to-row method as outlined
under 1 and 2.
METHOD OF CORN BREEDING FOR AVERAGE FARMER
The average corn grower does not have time or facilities for
accurate ear-to-row work. The method here outlined is very
simple, yet is probably nearly as good for the average corn variety
as the more complicated one previously given.
1. (a) Give special attention to a part of the field, or use a seed
corn plot.
(6) Plant and cultivate carefully, using the hill method,
and grow four stalks per hill.
(c) Each fall before frost select enough seed for the following
year's seed plot from stalks which give a good yield and
which grow in four-stalk hills.
(d) Discard only the very undesirable ears and store each
selected ear in a careful manner.
(e) Test all seed used for germination.
2. Save all good seed produced by the yearly seed plot to
plant the general field.
3. Continue 1 and 2 each crop season.
POTATO SEED (TUBERS) SELECTION
All localities are not equally good for producing potato tubers
for planting, therefore it will be better for some farmers to buy
tubers from a different locality. At University Farm, experiments
of the Division of Horticulture show that tubers should
be produced at some other locality if high yields are to be obtained.
For the farmer, however, who lives in a locality where
