Re: HYB: TBsxArilbreds

Thanks for your response, Donald.

The limitations in fertility is definitely a factor.  I understand 
from Sharon that quarterbreds (which should have more TB features in 
it) are harder to cross with TBs than OGB halfbreeds.  Strange.

My reasons for exploring this type of cross?  The same as my (one of 
two) hybridizing goal:  the search for even greater mystery in iris 
colors and patterns.  Am so hooked on those amazing blends and 
coloring.
