In this table the plants from parents having 25 or less 

 per cent, of hulled kernels give 119 hulled: 169 inter- 

 mediate : 217 hull-less. From this result it appears that 

 those plants having a low percentage of hulled or high 

 percentage of hull-less kernels tend to produce a rela- 

 tively high number of hull-less plants. On the other 

 hand, those plants having more than 75 per cent, of 

 hulled kernels do not give results so striking. There are 

 more hulled than hull-less plants, yet not strikingly so, 

 and the hulled do not run higher than the intermediates. 

 It may be, however, that the degree of hull-lessness as 

 expressed by the percentage may influence the segrega- 

 tion in the following generations. This can not be def- 

 initely stated from this cross, and further evidence will 

 be needed.
