Of the 14 groups of the 1922 crop 
having parental kernels with basal 
hairs absent all progenies in four groups 
had no hairs. In only four groups were 
found florets having basal hairs to any 
considerable degree. This shows that 
a strong tendency exists for parental 
kernels without hairs to produce prog¬ 
eny of that description, while paren¬ 
tal kernels with hairs show a marked 
tendency to produce progeny which 
segregate into the few and absent 
classes for basal hairs* 
The comparatively few kernels which 
were described as having abundant 
basal hairs in this study may easily be 
accounted for as chance variations in 
all cases. There seemed to be one ex¬ 
ception to this tendency, group 17 of 
the 1922 crop, but the results obtained 
in 1923 indicated that these few* ker¬ 
nels also were due to chance variation 
and not to any heritable difference. 
The data obtained in 1923 in the 
study of basal hairs in progeny of ker¬ 
nels bearing few hairs indicate that 
this character is more definitely in¬ 
herited than was shown by similar 
studies in previous years. Between 85 
and 90 per cent of the progeny from 
parental kernels bearing hairs was de¬ 
scribed as bearing hairs. However, in 
11 of the 12 groups in which the paren¬ 
tal kernels were described as having no 
hairs some progeny kernels were pro-
