The dwarf tomato plants are growing nicely. I noticed a bit of chlorosis in some when planted in the ground, which I also noted in some of the Roma plants too. Not sure why, and that seems to clear up in new leaves.
I decided to make a list of the dwarf cultivars that I'm testing this year, along with available trait info.
Variety / Info / Days to ripe tomato / Plant height / fruit size
Alpatieva 905A / a Soviet era Russian type from 1950 / 65 days / 18-24" tall / 2 to 5 oz
BrandyFred / Dwarf Tomato Project / 75 days / ? / 10 to 16 oz
CC McGee (light yellow) / late / ? / 4 to 8 oz
Clare Valley Pink / Dwarf Tomato Project / 84 days / ? / small to medium tomato
Dwarf Champion Improved / historic tomato (early 20th century?) / 85 days / ? / 3 to 8 oz
(Dwarf Champion was developed in 1889 . I don't know about the "improved". Size is Dw. Champion)
Dwarf Johnson Cherry / Dwarf Tomato Project / 65 days / ? / cherry tomato
Extreme Bush / historic tomato (Germany, mid 20th century?) / 50 days / 12 to 28 " tall / 3 oz
Tanunda Red / Dwarf Tomato Project / 75 days /? indeterminate / 4 to 10 oz
For comparison, here are some "normal", non-dwarf tomatoes. The Lemon Boy and Early Goliath Hybrid have fully recovered from their "wall'o'water" debacle and are nice and green and growing. Several tomato plants are blooming. Several of the dwarf tomato plants also have flower buds.
