290 BREEDING CROP PLANTS 



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 follow- 

 ing 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, experi- 

 ments of the Division of Horticulture show that tubers should 

 be produced at some other locality if high yields are to be ob- 

 tained. For the farmer, however, who lives in a locality where
