A BRACHYTIC VARIATION" IN MAIZE. 5 



affected plants. The fact that one progeny was free from this unde- 

 sirable characteristic affords evidence that it is inherited and that 

 strains free from this defect can be grown. 



Table II. — Measurements of maize plants of 14 brachytic progenies directly 

 descended from the original- variation.
