We have got exiictly the same iwsuIIh iih in h\, ixh nht'svu in 

 Table IX (compare Table III).

From the above Table we see that the ratio of plants with white- 

 margined and with fully -coloured flowers is 3:1, and in this case, when 

 we compare the ratios of the number of these two kinds of plants in the 

 field- as well as in the pot-cultures to each other we see also in the 

 latter case a certain deficiency of plants of white- margined flowers. 



We have got 4 families of plants which contain the " hukurin " 

 factor in homozygous condition, and 9 families where it is entirely 

 absent, as shewn in Table X. 



TABLE X. 



Total number of White- Fully- 



families in F^ margrined coloure<l

Folly -coloured ... 9 301 



3. Flower-colour. 



It would be a priori easily seen from the results in F.. that all F.. 

 plants with white flowers will produce in i^j again those with white ones. 

 Though I could not obtain many seeds from plants of these families the 

 results shewn in Table XI will fully confirm this expectation. 



We could find no families of plants which breed true constantly to 

 dark-red flowers.
