breeding - what can I do with citron
« on: June 26, 2017, 11:53:55 PM »
Does anyone have any ideas on what I could do with Etrog citron in terms of breeding?
I have flying dragon poncirus trifoliate and some changsha mandarin seeds. I'm interested in breeding a cold hardy lemon—a true lemon in the sense that it will have citron in its ancestry.

maybe (citron x poncirus) x changsha ?


Common lemons, in case anyone didn't know, are hybrids between citron and sour orange (basically)

kind of off topic but an interesting observation I found posted by someone in another forum:

Rez Zircon

"I've seen lemons grown from seed (random grocery lemons) survive Montana winters. I've heard of one that bore lots of fruit, growing unprotected at that, in Bozeman MT where winter temps routinely hit -30. An orange-grower friend tells me the trick to hardy citrus is own-root, not grafted stock."

"Yeah, we planted lemon seeds outdoors in Great Falls MT -- this was back around 1970 -- and they never got more than a foot tall, but seemed to have no problem surviving, and this was back in the era of really hard winters. I left in 1972 but my sister says they were still alive when my mom moved out of that house a few years later.

They lost their leaves in winter, just like any ordinary deciduous tree, and the little trunks did survive and re-leaf in spring.

Seeds were from random grocery lemons, whatever seeds were already sprouted when we cut one open. I think this started when we ran out of pots to grow 'em as houseplants.

It's been many years since I've seen a storebought citrus with sprouted seeds inside it, and now I wonder how that might relate to hardiness."

A lemon surviving -30 F unprotected, that is very difficult for me to believe.

Well I ordered a Citrumelo (poncirus x Duncan grapefruit). Maybe I can cross citron with that.
It could only improve the taste of the Citrumelo. haha  ;D

I lost a 10 ft tall swingle citrumelo and all my other trifoliate hybrids with the polar vortex events a few years ago, and they were protected with leaves packed around them in wire cages and plastic wind blocks. I've lost several Dunstan citrumelos over the years too with various levels of protection. I lost a pink grapefruit seeding from grocery fruit this year after it died to ground and came back last year in high tunnel for protection. Breeding regular lemon or any other citrus with a citrumelo is not going to make it survive Montana. I wouldn't try to leave s lemon tree outside in North Carolina unprotected because it would die. Ichang Lemons die here very well too. Montana. Might as well stick a seedling lemon tree in the freezer and take it out after 6 months and see how it does.

Socal2warm, have you tasted a citrumelo? I actually like swingle; tastes like a lemon, sour, but to me it's a lemon. They are sour. Dunstan to me tastes like an old fashioned white grapefruit, not offensive, but a bonified bitter grapefruit. Wouldn't win a taste test with ruby red, but if I can get one to live and bloom and mature fruit here, I would be thrilled. I've not tasted a citron, but from I've read about them, they are not good quality fruit with little pulp; I think you'd be taking a step backwards if breeding citrumelo with citron.

Etrog citron seed sprouting



I don't think breeding with citron is "taking a step backwards". After all, citron is the ancestor of modern-day lemon, and, while it doesn't have a lot of pulp inside, the fruit of the citron is very fragrant. Citron fruits can be pretty big too.

Another advantage? Being an original species, citrons produce all zygotic seeds. Edit: after looking it up, it apparently 50-60 percent of the seeds in citron are zygotic.
