The yield obtained-from any variety depends upon its adaptability to local conditions, soil type and the environment under which it is grown. All varieties recommended in this publication have some merit, but they also have some weaknesses-which show up more some years than others. In some years, only early maturing varieties produce a crop, while in other years the late varieties give the highest yield. Some varieties are resistant to the common diseases, while others are susceptible and may result in crop failures. Because of these varying conditions, no one variety is best for all locations.
