The lines 250—16a and 250—20a may be studied further with 
profit. We have seen (table No. 2) that mother plant 250—16 was 
a dwarfed plant with few branches and few seed pods, and that 
mother plant 250—20 was a large upright plant. The progeny of 
these two plants along with that of 250—14, which is inserted for

a check as being about the average of the lot, are shown in the 
following curves. Fig. 5 represents the character “height”, Fig. 6 
“width”, Fig. 7 „number of branches“, and Fig. 8 “number of seed 
pods’. In each Figure the solid line represents the progeny 250—I4a, 
the broken line represents progeny 250—16a and the dot-and-dash 
line represents progeny 250—20a. 
For the constants, mean, standard deviation, and coefficient of 
variability, with their respective probable errors, of these three lines, 
the reader is refered to tables 8, 9, 10, and rr. It will be seen that
