SEED GROWING 109 



in addition, a thorough working knowledge of 

 the science of plant breeding is possessed, suc- 

 cess will be more certain and earlier. 



What has been accomplished with corn and 

 cotton can be attained with the vegetable crops. 

 In fact, the problem is half solved with the 

 vegetables. There is an abundance of forms. 

 What is needed is intelligent selection of parent 

 stock and persistent line breeding to establish 

 and maintain high-grade strains of seed. New 

 sorts are not needed. Seed true to name, with 

 good growing power, will solve the problem. 

 That these results can be attained is amply 

 proved by the success of the United States De- 

 partment of Agriculture in its efforts to elimi- 

 nate the green sport from Grand Rapids let- 

 tuce, and in establishing a superior strain of 

 early cauliflower, and incidentally in demon- 

 strating the commercial possibility of growing 

 cauliflower seed in Eastern United States.
