Hey Blue.........sounds like you got some killer crosses happening there buddy. Good luck with them!
I'm pragmatic , it will be 18 months to 2 years down the road before they *really* work out beyond just the initial crosses. Gut feeling , the BB cross will be fairly homogenous and BB dominant , the BW cross is likely to throw several different phenos from mild to wild , sorting through those could take a while and once that's done I'll have to inbreed or backcross , though it's not nearly as scatterbred as it looks if one looks beyond the first two generations.
Here's a trick that often works when lining down the breeding on a potential cross , utilise a 4-8 generation canine or equine pedigree sheet , it will give you a better fix on where the genetics lead back to than the usual square systems.
And in reality breeding a plant of any sort to perform is no different than breeding performance stock in an animal endeavor , inbreeding , linebreeding backcrossing , outcrossing...they are all equally applicable to plants.
And the same exact pitfalls apply , you can breed so tight that you HAVE to go "out" to restore vigor , conversely you can scatterbreed so badly that it's well night impossible to identify where recessives with a negative impast are coming from and cull them from your "bloodlines".
An example....I completely bred out the maternally linked genetically carried Demodectic Mange ( autoimmune system deficiency) in A specific bloodline of Leopard Curs ( Catahoulas)...simplistically speaking if a bitch threw pups that showed Demo she didn't ever get bred again , nor would her progeny ever be bred and all her sisters or half sisters descending from her dam (mother) became suspect.
Where am I going with this...........when selecting some folks won't track the clones of the individual mothers , this is key to the selection process , and don't get too silly-happy off the first set of clones off a given mother , wait a bit , take another coupe of sets and see how the performance holds up or indeed if it does...........
