T]ie faint yellows are expected to be constant. Twelve families raised 
were all constant. The actual number's are given in Table 31. 
In the case of the cross “ Kurafusagi ” x “ Nagoya-sliiro ”, the red colour 
of the awn was more distinct than the former case, hence the agreement of 
the expected to the observed numbers was close. In the F 3 , was obtained :

Thirty two faint yellow gave all constant families. See Table 32. 
(c) The Cross : Red x Purple. 
The relation of the colour of the stigma, awn, palea, glumes and the 
leaf-sheath was studied by the cross “ Hanbun-nento ” x “ Genrokumoclii ”. 
The characters involved in this cross which were subjected to investigation 
were as follows : 
“ Hanbun.” 
“ Genroku.”.
