in the pod. The seeds averaged lowest in weight in the 2-seeded 

 pods and there was but little difference in the 3-seeded and 

 4-seeded pods, the former being the heavier. For position in 

 the pod, the basal seeds averaged lightest and the middle seeds 

 are the hea\dest, those from the middle of 3-seeded pods being 

 heaviest of all.

Viability. Germination power is greatest in the seeds from 

 2-seeded pods and there is but little difference between those of 

 the 3-seeded and 4-seeded pods. The seeds borne in the middle 

 have a higher viability than either the basal or tip ends. 



Vigor. The seeds from 2-seeded pods produce a greater 

 average weight of seedling than those from 3- and 4-seeded pods. 

 In pod averages with a single slight exception, there is a uniform 

 negative correlation between seed-weight and both viability and 

 vigor.
