plants for the three characters concerned is shown in Table II, together with the 
data for 55 F 2 plants tested in F 3 . From the results of both F 2 and F 3 it is evident 
that the pubescent-glume character segregates independently and is not linked 
in any way so far as this material is concerned. Considering pubescent glume 
alone, it segregates in a simple 3:1 ratio with pubescence dominant.

CONCLUSION 
The results presented indicate that the character pubescent node as found in 
the Velvetnode variety is very closely linked with the bearded condition. Whether 
the few aberrant cases are really crossovers or may be explained in another way 
can not be definitely established at this time. The breeding tests that are now 
under way will shed more light on this question.
