Table V. 



The figures show an obvious 3 : 1 ratio, similar to that of Table III, and 

 it appears that a somewhat similar inhibitory factor may be concerned. If so, 

 this factor difiers from that already described in that it has no effect on the 

 internode and the inhibition in the glumes is not complete since, as already 

 noticed, they possess a distinctly yellowish tinge. It may be noted that in 

 some of the families concerned one or two plants occurred in which both glumes 

 and internode were entirely green. These must have been natural crosses 

 from outside as they also varied from the group in certain other characters. 

 There is little doubt that they possess the ordinary inhibitory factor, crossed 

 on from another group, and their progeny will be of interest in their 

 connexion. 



To return to Table IV, in No. 432-N, three groups appeared, viz., green, 

 pafchy-gold and gold, in the approximate ratio oi 1 : 2 : 1. These groups, which 

 are shown in Plate II, figs. 8-12, were distinct and easily separable. The 

 greens were of the same yellowish type as has already been described and the 

 golds were of an ordinary medium shade but with small green areas at the apex 

 and base of the grain. In the patchy-golds the colouring varied considerably, 

 both in shade and extent (Plate II, figs. 10-12) even on the same plant. It 

 was always irregularly patchy and quite distinct from the piebald type 

 (Plate II, fig. 1) which will be described later. .
