always— lias the mode at twelve rows. In one case cited 

 in Table VI, No. 24 X No. 53, nearly all the F 1 progeny 

 were eight-rowed. It might appear from this, either that 

 the low number of rows was in this case dominant, or 

 that the female parent has more influence on the resulting 

 progeny than the male parent. I prefer to believe, how- 

 ever, that the individual of No. 53 which furnished the 

 pollen was due to produce eight-rowed progeny. Un- 

 fortunately no record was kept of the ear borne by this 

 plant, but No. 53 sometimes does produce eight-rowed 

 ears. 



When a race with a mode higher than twelve is crossed 

 with an eight-rowed race, the F x generation is always 

 intermediate, although it tends to be nearer the high- 

 rowed parent. Only one example is given in the table, 

 but it is indicative of the class. These results are rather 

 confusing, for there seems to be a tendency to dominance 

 in the twelve-rowed form that is not found in the forms 

 with a higher number of rows. I have seen cultures of 

 other investigators where 12-row X 8-row resulted in a 



"Approximately.
