188 THE INHERITANCE OF CHARACTERS IN RICE, II 
The results of a number of families in which three groups were separated 
are given in Table I, which shows a 7: 2: / ratio.

The factor I. 
As already noted the presence of J changes any form of golden colouring 
of the inner glumes to a corresponding degree of dark furrows. This factor 
was described in Part I, p. 82, as an inhibitory factor for gold, and figures 
were given in Table III, p. 81, showing a 3: 1 ratio of green : gold due to this 
segregation. The so-called green types, in reality various forms of dark 
furrows, were described as green merely to indicate the absence of gold. The 
same 3: / ratio for the presence and absence of J has been repeated in a very 
large number of later families, the two groups appearing, in all cases, being 
corresponding types of dark furrows and gold respectively.
