Susan: I grew a thousand or so tomato plants for the farmer's market this spring. I've been sharing the heck out of them... I expect to take them 2 to 3 more weeks.
My three favorite varieties are:
Ot'Jagodka, a super early red saladette tomato, with 2-3 ounce fruits. I even had ripe fruit from this to take to market today -- so I could show off what the fruits look like.
Joseph's Earliest Landrace, red saladette tomatoes.
Joseph's Slicing Landrace, which are about 8-10 ounce red fruits.
I've also been taking 6-packs which are a mix of the above plus a yellow slicing tomato. Those have been very popular.
I really like having just a few varieties that really thrive here... I'm not very happy at all the Brandywines and Beefsteaks I see the nurseries offering around here.
All are determinate. They ripen most or all of their fruit before the fall frosts. I trialed hundreds of varieties and dehybridized dozens to arrive at these populations. I'm getting much more clever about selecting for traits that thrive in the valley.
Alas, people ask what they taste like: I have to say like any other (gaggy) tomato.
