158 CORRELATION OF COLOUR CHARACTERS IN RICE 
6. CoLoUR IN THE INNER GLUMES. 
{n many varieties with colour in the outer glumes, colour is also found 
in the inner glumes, apart from the spot of colour at the apex, the apiculus. 
This applies to all the varieties experimented with, all with colour in the 
outer glumes having the inner glumes also tinged with colour, and the two 
characters have been found to segregate together. Thus the table above 
applies also to the inner glumes. 
\ 7. COLOUR IN THE APICULUS. 
The apiculus or apex of the inner glumes is coloured in a large number 
of varieties. The colour consists of a spot at the extreme tip. As in other 
localizations, colour in the apiculus has been found to be due either to a 
single factor or to two or more interacting factors. Actual results obtained 
are given in the table.
