I planted both saved and commercial tomato seeds this year, and even from the same parent, some are not the same. Lessee... what do I have here... so far nothing has chewed on any of them, tho the potato leaves are full of holes. No ripe fruit yet, tho plenty in progress
#1 - offspring of last year's pest-proof plant, with the very oily leaves that even starving grasshoppers didn't touch (it was an only child so self-fertilized). Smaller compact upright bush, slow to bloom (no fruit yet) but it's also in the worst spot and doesn't get the deep water the others do. (The large ones are 4-5 feet tall and eat passing children.)
#2 - from super-good storeboughts (the kind that are 5-6 2" fruits set evenly along a stem). Big strong upright plants. One is making round fruit that look like the parent, and the other is making what look like Romas, with a bit over half the flowers setting fruit.
#3 - commercial seed 2004, "Burpee Super Beefsteak" (same seed as last year's pestproof model) large vigorous grower, lot of blooms, few fruit as yet.
#4 - commercial seed 2017, "FerryMorse shish kabob" - smaller strangly-looking plant (trying to grow up the corn like a vine), many small fruit. Initially didn't set well but started doing so once the weather got hot. Accidentally broke off a piece and just stuck it in the ground and it's growing pretty good.
#5 - this space unintentionally left blank, because one of my numbered sticks went missing.
#6 - commercial seed 2017 "Brandywine pink" (heritage supposedly) - very large, upright, and vigorous; world's ugliest tomato plant, big flat leaves (some hand-sized), if I hadn't planted it myself I'd have pulled it up as a weed. Leaves smell like gasoline, but the flowers smell unusually sweet (for a tomato) and are very attractive to bees; I notice they visit it first when they come up the hill in the morning. Stamens are initially completely hidden, then the flower bursts apart and exposes the stamen, which is quite large (not long but thick). Initially poor fruit set but once it got going, setting a bit over half.
#7 commercial seed 2004, "Burpee Heatwave Hybrid" - smaller strangly-looking plant, so far indistinguishable from #4, likewise a slow starter but now setting many small fruit.
Then there are two I bought as started plants:
Bonnie's "Favorite" -- big strong upright plant, probably about 60% fruit set.
Bonnie's "Cherokee Purple" (heritage) -- huge bushy plant, upright center with large strong lateral branches. Started setting fruit by 10" tall, and 100% of blooms set fruit -- it has about 12 pounds on it already. Some are softball-sized and just starting to darken. The biggest fruit are in tight clumps in the middle so despite the weight, don't drag it over. Flowers show a well-exposed stamen, thicker than average, which I expect is why every single blossom sets fruit, so far without exception. (You can tell, because no scars from flowers that fell off.) The earliest 2 or 3 clumps are all self-fertilized (it bloomed weeks ahead of its neighbors). For sheer volume it beats every tomato I've ever seen, so I hope it tastes good!!
And the bees had their way with 'em so other than the early blooms, gods know what hybridized with what. #2's parent was evidently open-pollinated since the offspring don't match at all.
Also planted some spaghetti squash seeds from a random locally-produced fruit (which was a good keeper). Four plants was overkill. ONE would have been overkill. Kudzu has nothing on 'em; they've taken over all the open ground and are now invading the corn. And they make zucchini look inadequate. I read that you could expect 4 or 5 per vine... wrong!! Each has around 30 squash-in-progress (about 80% fruit set) and no end in sight. Planted April 14th and the first fruit reached mature size by July 10th. Two types -- one cream-colored like the parent, the other mottled-green.
