C... the factor for the color flower; 



c the factor for the white ; 



F the factor for the " Hukurin " ; 



f the factor for the normal, totally colored flower; 



S the factor for having activity of making the " Star " 



pattern on the corolla in the presence of homozy- 

 gous condition of the factor C and F ; 



s the factor for not having above activity. 



The genotypic constitution of the totally colored flower corresponds 

 to CCffss, of "Hukurin" to CCFFss and of "Star" to CCFFSS. 



Hybrids between the varieties " Hukurin " and " Star " do not 

 resemble anyone of their parents, but are intermediate in design 

 between the " Star " and the " Hukurin," the offspring gave " Huku- 

 rin," intermediate and "Star" in the proportion of 1:2:1. But, 

 the hybrid between the white flower variety giving the hybrid 

 " Hukurin " by crossing the totally colored variety and " Star," was 

 •"Hukurin." 



So, the genotypic constitution of intermediate must be CCFFSs.
