Good question, Francesca.
I think the best answer is probably practice. Over the last few
years I've grown lots of plants from the TB X AB cross. Knowing what
those are supposed to be, I look for proof. It's become habit to
look for signs the cross is true - or not. In a few cases I've felt
sure it was not and some of those crosses were tossed without waiting
for every seedling to bloom. Bee pods are rare here, but they do
happen. As a result I don't toss lightly. Here, even without the
sibling showing the signal pattern, I'd mark it as an OGB- type. It
actually has more aril 'presence' than the one with the signal even
at a glance. It does, in fact, have some color under and close to
the beard typical of those crosses. Usually I find such seedlings
give hints even before they bloom. Somehow most don't grow quite the
same as a TB - probably because they aren't TBs. These seedlings
didn't do that and so were a surprise. I'm given to excessive doubts
about crosses I grow because I'm continually surprised by what I
see. But here I have no doubt though I can't exactly pinpoint why.
Not yet, anyway. I think the sibling backs me up pretty well. They
would be the same, wouldn't they?
