as in the previous cross. The equation in this case is found to be : 
14. n ; 3 
s 5 thus n = 3,5 corresponding to €. 0. % 22,2. It is doubtful 
whether the results of the Fs-method or of the F3-method shall be 
taken as decisive, as the number of F,-families is rather small, as said 
before. 
DISCUSSION OF THE FACTORIAL SCHEME. 
The factorial scheme has been mentioned in short already on 
pag. 306: I shall discuss it more fully here. One factor, R, has been 
denoted for the anthocyan colour pure red, and two factors, B and V, 
for the transferring of this colour into bluish red and violet respectively: 
they change further the red ground colour into deep blue when 
both present. 
(RB=Bluish red) 
B 
R Pure red RBV = Blue 
\" 
(RV — Violet 
There is, further, a factor for full flower colour: »diluted» forms 
originate when this factor is absent.
