Andy, it is a compilation of multiple sources. I can probably find the references. I track the information for the ones that I have grown.
These are the ones I have grown. I am currently working on growing out several of the F1 hybrids to stabilize the lines. Skykomish is F8/F9 so that is stable already, though a little too long season for my climate.
Homozygous for Ph2 and Ph3
Iron Lady
Skykomish (from Tom Wagner)
Heterozygous for Ph2 and Ph3
Defiant
Jasper (probably has both - not confirmed, unsure if heterozygous or homozygous)
Homozygous for Ph3
Plum Regal

If you are looking for homozygous Ph2 and Ph3, here is information I had tracked down in the past. Homozygous for Ph2 and Ph3 Iron Lady Lizzano Skykomish (from Tom Wagner) Crimson Crush Heterozygous for Ph2 and Ph3 Mountain Magic Mountain Merit Defiant Jasper (probably has both - not confirmed, unsure if heterozygous or homozygous) Homozygous for Ph3 Plum Regal Homozygous for Ph2 Legend (OP) Possibles/Probables Matt's Wild Cherry - probably Ph3 JTO-545 - probably Ph2 If you are looking guarantee that both Ph2 and Ph3 are transferred into your F1 (as heterozygous), you need to make sure you are using a homozygous parent. So Lizzano does have both genes? |

Do those resistant tomatoes taste good enough? That might be a dad's project.
Your son will probably want something that tastes great and looks different.
I'm doing a similar project with my son with fava beans. He started at 2, now 4. Selection criteria is wonderful raw taste, production and it must grow well. It's amazing how he goes down the row and starts ... cull that one, and that one ... not adapted.

I grew Mountain Magic and Merit this year and they both tasted fine. I forget which is which but one is a golf ball size and the other bigger. Also grew plum regal and it tasted good too and made tons of smallish fruit. Plum Regal had rather thick skins and some left laying on the table started to shrivel. I'v never tried it before but they might be good ones to sun dry.

I like your fava bean project, ilex. It's interesting to think about how projects with inbreeding and outbreeding plants would lead to different experiences for a child. Both good, but different.

I thought i had replied to this already. Guess not. Sounds like a neat project. I havnt grown many tomatoes, but apparently they vary for flavor or at least acidity. Hoping to grow some this year.  Joseph Tychonievich talks about tomato selecting in his book: Plant Breeding for the Home Gardener: How to Create Unique Vegetables and Flowers. He also talks about it on npr. I'll see if i can find the link. I cant seem to find the radio interview. www.splendidtable.org/story/the-lynne-rossetto-kasper-tomato-plant-is-here |

Great project; favas are like loquats: lots of fiddly work for a little reward; just the ticket to keep small children involved in the garden when there isn't something more pressing, like breaking clods or putting worms in a can for later fishing; that's how Grandad infected me with the gardening bug. I'm certain that cherry tomatoes were developed for the same toddler-occupy-purpose. |

Got my first set of crosses started today. One cross is Speckled Roman x Stupice. The other is Pear Shaped Tomato and one of three big slicers. I made crosses with Brandywine Cowlicks, Old German, and Siletz, but am putting off deciding which to use until I've tasted them all and seen how they grow in my garden.

I made some changes to my starting varieties after seeing how they grew out in my garden last year and doing taste tests. Wow, Brandywine Cowlicks is a tasty tomato. Last summer, I managed to get several Pear Shaped Tomato x Brandywine Cowlicks tomatoes to mature before the late blight took the plants out. All of my Speckled Roman x Clackamas Blueberry crosses failed, between late blight and blossom end rot, so I grew a couple plants over the winter under growlights. That worked pretty well, and I had seeds from both crosses when planting time came around.
I've done my second round of crosses and have one (Speckled Roman x Clackamas Blueberry) x (Pear Shaped Tomato x Brandywine Cowlicks) fruit set. The PST x BC plants are the most vigorous plants in my garden. The plants from the other cross are pretty mediocre. If either ends up being particularly tasty and productive, I have plenty of seed left for future gardens.

I just finished processing the seeds from my successful four-way tomato crosses and have about 150 seeds. I was hoping for more, but my tomato emasculation skills are kind of pitiful. Still, should be plenty to grow out next year, when the fun really starts.

My son and I planted two 72-cell trays with the four-way tomato crosses. Got to it a little late, but I think we should be fine. Yesterday, we selected for vigor and for dark purple color on the bottoms of the leaves. It turns out that his primary goal is to have a purple tomato, since purple is his favorite color. One of the grandparents is Clackamas Blueberry, so the genes should be in the mix.
It was interesting seeing the variation in leaf structure, and I was pleasantly surprised by how few seemed to be weak plants. Only about 1/4 were noticeably smaller than the others, and that might have been largely caused by not watering them for a week after we planted them, since we were out of town on vacation.
