Here's something that's been bugging me for a while that I can't seem to find something written on, so I'd be interested in your thoughts to see if we have any differences of opinion...

Time for some algebra !...

The question is....

**"How would you write the CORRECT parentage formula (name) for seedlings grown from from "F2 self set" grexes that came from "unnamed" hybrid plants, under the following scenarios ?"**...

Scenario 1. F2 seedling from seed from a plant -

**'A x B'**Scenario 2. F2 seedling from seed from a plant -

**'(A x B) x C'**Scenario 3. F2 seedling from seed from a plant -

**'(A x B) x (C x D)'**

To my way of thinking, you must write them like this;

1.

**'(A x B) F2'**2.

**'[(A x B) x C] F2'**3.

**'[(A x B) x (C x D)] F2'**Have I got it right, or completely wrong ?...Why I ask is I've seen seedlings just labelled as; 'A x B F2'...which is misleading, as you then don't know if the pollen parent "B" was an F2 plant... or the seedling is actually an F2 of A x B !!

Obviously when you add multiples into the mix (like in 2 and 3 above), it gets more complicated, but also more important that the brackets are used CORRECTLY to signify the correct grex name.

Thoughts anyone ?
