RT x GDZ F1 update

Well, disease is taking over the RT x GDZ #16 F1 despite my earlier pruning.   Not too surprising.  This may impede ability to assess fruit phenotype fully.  It's a bit confusing.  The first two fruit to form and grow are clearly ultra-fasciated as per the unique RT and GDZ phenotype.  In addition there was the megabloom from the last post; that fruit is not growing much.    However, there is another fruit that has an intact, flattened ribbed phenotype a la Costoluto Genovese.  And the newer flower to form seem modest-sized and have a modest number of petals, e.g. about 6.   So I am wondering if the first fruit were "megablooms", but the more typical fruit phenotype will actually be less fasciated than either parent.  That would be very interesting and suggest partial complementation, e.g. two separate loci.



Not ultra-fasciated, just ribbed and a little catfaced

Sick plant

Rest of patio tomatoes doing OK
