Tomato germination 2018

I had to re-sow some of them, around 4/8/18.   More ZPT - these seeds were from 2013 and had 0/4 seeds germinated, so I re-sowed 2 seeds x 6 wells and got at least 6-8 or so up.   Also re-sowed several F4s, and one or two other heirlooms.    By 4/26/18, almost everything has at least some germinated - at mostly pretty good rates - and all have been transplanted.  The only failed germination was Lucky Cross.  Oddly this was a gift from Tomatoville this year, so they should be "fresh" seeds.  However I didn't plan on this variety anyway so no big deal.

Random notes: I sprayed Daconil on the soil tops after sowing.   By 4/25, just a couple of the last few seedlings that I had not transplanted yet had beginnings of damping-off, which is not bad out of about 70 or so seedlings.  However, I sprayed those guys with Daconil, gave 'em more soil, and the next day seemed more stable.  I guess if the infection is controlled and they can develop new roots above the old infection point they might make it.

Sowing heirlooms

4/1/18 I also sowed these:

BC, BZ, BTD, BW, CA, CP, CG, FL, GZ, HC, GDZ, GZ, HC, KB, LC, MS, RT, SG, WB, ZPT.    = 18 varieties!

New abbreviations:
BZ   Black Zebra
PBTD  (Pink) Berkeley Tie Dye
CA  Carbon
GDZ  Godzilla
LC    Lucky Cross
MS   Mr Stripey
WB  White Beauty

Sowing F4s

4/1/18 -  I sowed F4 seeds from these 2017 F3 plants from the IRxCP cross.

8A-6, 8A-7.                         
Gf. Biggest of the 8As. 250-300 g.  Might see an increase in purple color in F4s?

46A-2                                   
Gf, globe, nice purple

55A-1, 55A-5, 55A-7.  
Gf.  Better purple than 8A but might not be quite as big: 150-200 g.

10B-1
Not gf but good size and good purple, so kinda neat.  Gf homozygotes might emerge in F4s. Chance of any one F4 plant being gf/gf is (2/3 x 1/4) = 1/6.  

28D-3            

The purple-tinged cherry.

Not sure how to handle the nomenclature going forward, but I don't see why after this point I'd be inclined to save fruit from more than just my favorite single individual from any one line.  Going forward I can keep the F3 identifier and just append the generation, e.g. 8A6-F4, 46A2-F4, etc.
