Pods per plant. 
Diagram 2. Regression of ovules per pod on number of pods per plant. The 
end points of the lines are given in the table. 
variation in the number of pods is very great ^ and that in consequence 
the extreme cases are represented by very few individuals. Thus in the 
HH series the number of pods per plant ranges from i to 67, but of the 
^ The coefficients of variation for the number of pods per plant (unweighted) for 
the series illustrated in the graphs are: 
HH = 51.02 FSS = 49.34 
HD = 48.97 GGD = 44.07 
GGH = 38.60 LL ^ 58.55 
USS = 38.36 
Mean = 46.99
