Variation in Corn 5eec? 



Mr. Burbank finds malerial for most of his experi- 

 ments in variations as to one quality or another that appear 

 among plants oj the same species. It may or may not be necessary to 

 accentuate variation by hybridizing experiments. The range oJ 

 variation that may he shoum in the seed oJ a single species 

 is illustrated in this lot oJ kernels oj corn, which show 

 surprising diversity in shape, size, and color. 

 Numberless new varieties could be devel- 

 oped through selective breeding from 

 such a lot oj seed as this.
