hairs. The small kernel of the spikelet was never awned 

 but had an occasional sprinkling of dorsal hairs. The 

 base was more like the saliva type, yet appeared to be 

 more intermediate in type with some basal hairs on either 

 side of the base but not at the back. 



When the seeds from the first generation plants were 

 sown, a number of different types appeared in the second 

 generation. There were some that resembled the two 

 parent forms and also other types different in color, 

 amount of awning, pubescence, and the like. 



As regards color there appeared four types, black, 

 gray, yellow and white. The white ones, of which there 

 were only four, were tested later and proved to be gray, 

 thus leaving only the three color types. The black oats 

 were of two general types, those having the two strong 

 awns and pubescence on both kernels and the wild base, 

 and those having pubescence on the large kernel and 

 sometimes on the small one and with an intermediate or 

 sativa type of base. Some of these forms were awnless 

 and others possessed varying amounts of awn which were 

 in some cases strong and in others weak. 



The gray colored oats were both pubescent and smooth, 

 some fully awned, some partially awned, and some awn- 

 less. They also segregated as to type of base. 



The yellow oats, however, were all smooth and pos- 

 sessed very few or no awns. No yellow oats developed 

 the strong awns similar to the wild type. 



The segregation as to color and percentage of awns of 

 the second generation plants is shown in Table I.
