Tromboncino Genealogy

This is the first year I’ve grown tromboncino, so I don’t know how normal this is. Most of them have had a light, lightly striped green skin with a pale, dense, zucchini-like flesh. But one plant is bearing darker green skinned tromboncino, with yellower, more squash-like flesh.

I’ve been watching and noticing to see if there is any difference in productivity or resilience, but the only difference I’ve been able to see is the fruit colour.

I like both types, and I’d like to grow both types next year so I am leaving a couple of fruit of each type to fully mature to save seed.  Trouble is, I have only one plant bearing the dark green type. I could try hand pollinating, using a male from the same vine to fertilise a female flower. 500m2 in Sydney has a good little post about how. But self-pollination is only successful about a third of the time with cucumbers, so I might not get any fertile seeds that way. And even if I do get fertile seeds, they will have all the problems of in-breeding. So I’m just going to hope that it’s not a recessive gene, and that the mama genes are strong enough to shine through whoever the bees decide to make the dad.

But I might, next year, try planting only one kind at a time so I can get some good second generation seeds of those dark green ones. I’d hate to lose the variety altogether.

    I’m growing it for the first time too. I posted a photo a few days ago of my first one… so far we’ve had two meals from it and there’s still nearly half left. Awesome! (I like the way the seeds are all at one end. Very civilised.)

    Thanks for the link Linda 🙂 Am I right that these are happy to grow up a trellice? If so, I might have to try these next year instead of zucchini. I’m sick of the zucchini plant taking up most of my garden bed!

    That’s one of the reasons I like them too. They are a bit triffid-like though – they need a big trellis.

    How cool that there are dark green ones too! I’m growing it for the first time too this year and only have babies so far. My vine has gone NUTS!
    I like that they stay crunchy when cooked too. Nice and refreshing.

    How can you tell from the seeds which colour fruit you will get?

  • Linda January 29, 2012, 9:39 pm

    Hi Elaine, I can’t tell from the seeds, but I can record which fruit they came from.

    I’m growing them for the first time this year, and I planted 3 plants, one of the 3 are coming out dark green too! This is the first I’ve found of it happening to someone else.. I picked my first 2 trombonchino yesterday, one light in colour n normal n one daark green from the other plant so I could try both n see the differences, not sure how I’m going to cook them yet though.. xD
