Germination of Seeds from F2 Plants 
The seeds from plants nos. IIIi, III2, III3, Xi, and X2 were sown shortly 
after they were collected (see table 3) . 1 1 of the 80 seeds germinated and 
produced 11 plants. These plants were the first of the F3 generation of 
female plants. 
Including the seeds from 27 plants, F2 offspring of plant no. VII (see 
table 4), 505 seeds were sown. Altogether 104 germinated (see tables 4 
and 5), giving an average percentage of germination for the whole genera- 
tion of 20.1, approximately the same percentage as for the seeds of the 
Fi generation. 
F3 Generation from Female Plants 
The II plants raised from seeds of plants nos. IIIi, III2, III3, and X2, 
and the 42 plants of the F3 generation from plants nos. VIIi to VII27 in- 
clusive, were grown to maturity, a total of 53 plants. The other 51 plants 
were discarded as soon as their sex was determined. All of the 104 plants 
were prevailingly female. 
The 53 plants produced 367 seeds. They were not treated like the 
F: and F2 generations. The seeds as they matured were collected but 
those from different plants were not kept separate. It was not thought
