TUBER CROP PROJECTS 205 



3. Choosing varieties. — In the choosing of varieties, a number 

 of factors should be considered, the following being the most im- 

 portant : (1) Quality. Consumers are demanding quality. • They 

 want tubers that are mealy, not soggy, when boiled, and that are 

 also mild in flavor. (2) Yield. Some varieties produce much 

 heavier crops than others. Early varieties do not yield so well 

 as late ones. As a rule the tendency is to sacrifice quality for 

 quantity, and this tendency is unfortunate because consumers are 

 generally willing to pay a good pfrice for potatoes of high quality. 

 (3) Shape. The flat-round and oval tubers are the most popular 

 shapes. Deep and numerous eyes are objectionable. (4) Disease 

 resistance. Some varieties are more resistant to disease than 

 others, and they are also more vigorous in growth. 



Among the early varieties. Early Ohio and Irish Cobbler are 

 very popular, the former being of high quality. Popular late 

 varieties are Green Mountain, Rural New Yorker, Carman No. 1, 

 Carman No. 3, Sir Walter Raleigh, and Heath's Late Beauty. 



An excellent plan is to consult your dealer and your neighbor 

 farmers before making a flnal decision concerning varieties which 

 will pay best on your particular soil and market. It is also exceed- 

 ingly important to select varieties with special references to 

 disease resistance as, for example, the dreaded potato wart disease.
