BY THE SELECTION OF SOMATIC VARIATIONS. 31 



TABLE 6. Pedigree of 6 plants giving spontaneous yellow. 



1 Chimera. 



Including the cases of spontaneous appearance of yellow with sec- 

 torial bud variations, the ratio of frequency was 1 to 1,120. The ratio 

 for the sectorial bud variations alone was about 1 to 2,570. 



Plants with pattern yellow-green-red blotched. All of the plants grown 

 with this pattern (fig. 6) belonged to clone 11, and all, excepting 3, de- 

 scended from the plant 1171, which produced a series of branches with 

 this pattern, as already shown hi diagram 1. The record of these 

 plants is given later in table 13, but may be summarized here as given 

 in table 7.
