DISTRIBUTION OF VALUES FOR RATE OF DECREASE (b) FOR THE VARIETY

quite of the average of the previous year. The parents of this 
series were plants of high values. While the series showed some 
regression, the variability of +0.77 was low and the average 
value of a was higher than that of other series from parents of 
lower value. The results obtained in these two lines suggest that 
in this variety lines of descent may differ and that such differences 
may be high or low according to the performance of the ancestry.

As shown in TABLE 43 the values of 0 were more variable than 
the values of a. The characteristic performance gave minus 
values for the rate of change and there was on the whole less 
variability than was seen in the hybrid generations reported 
above; here there were no cases of 4 values, and only one plant іп 
the 0.000 class. 
In this variety the branching of laterals was very complete, 
as shown in PLATE I3, А and B, and there were, as a rule, rather 
few heads in clusters such as are shown in PLATE 13, C and D.
