Fic. 1. Regression straight lines showing change in seed weight associated with 
variation in number of pods per plant. 
are based by clubbing together plants with similar numbers of 
pods, since in many of the experiments the range of variation is 
too narrow to permit of such combination. 
Finally, it is to be noted that in general about five seeds per 
plant have been weighed. When the number of plants with a
