Both have about the same proportions of green and yellow, except that the relative position is reversed. Both groups agree quite closely in the percentage of constant plants. In the latter, however, bud variations were 2.5 times as frequent. The position of the yellow in the center seemed to increase bud variations involving green and yellow over that in plants with the yellow at the border. DISTRIBUTION OF BUD VARIATIONS AMONG DIFFERENT CLONES. The wide range of variation both of fluctuations and of bud variations emphasized in the summaries already given was realized in a series of plants derived by vegetative propagation from two plants having the same color pattern. The records of pedigrees show that marked differences appeared among the various clones with respect to constancy and to the range and the frequency of bud variations. This is shown quite clearly when the data regarding the main clones derived from plant 1 are grouped together as arranged in table 12. The main clones 11 and 12 were derived from two branches of plant 1 which had the same color pattern. Although the branches were identical in appearance, the two progenies were quite different. 62 per cent of clone 11 were constant, while 45 per cent of clone 12 were constant; but in the more constant clone 11 there were proportionally BY THE SELECTION OF SOMATIC VARIATIONS. Table 13.--Record of clone 117--Continued. more than twice as many bud variations. Clone 13, which was derived from a branch that was green-red blotched, gave a progeny (of several patterns) of which 54 per cent were constant, but bud variations were very infrequent. Clone 14, with nearly the same percentage of constant plants, prod...
