This text is full of factual errors and Turing criteria is not met.I still think micrantha is just a form of hystrix but didn't know it is a progenitor of modern limes. I also expected maxima to feature more prominently and medica to feature less.I like the way you think, but I don't think that's true here. I seem to remember reading that kaffir lime was a hybrid of some other type of papeda (I can't remember what it is right now) from which it derived its cold-hardiness. (It was some weird one, not as cold-hardy as Ichang papeda, but maybe I'm not remembering any of this right)
I think kaffir limes are descended from a different papeda ancestor than common limes. Isn't kaffir lime about as cold-hardy as the more cold-hardy oranges? While common limes are the most sensitive out of all the different citrus groups to cold, slightly more sensitive than common lemons.
Edit: I think it may have been C. latipes, also known as Khasi papeda.
But yes, it's well known that limes are descended from C. micrantha. Another little uncommon fact, C. micrantha is incredibly high in furanocoumarin levels, over four times higher than bergamot! Probably not a good idea to put the essential oil on your skin.
So lemon's primary ancestor is citron, for lime it is C. micrantha, and for kaffir lime it is Khasi papeda (assuming I'm remembering right)
I do suspect citron, C, micrantha, khasi papeda (and Ichang papeda too) are closer related to each other than they are to C. reticula or C. maxima, but that's just judging by morphological appearances.
To test this hypothesis, one could root Prague, and make a root cutting to root. The plant should be all L3 and thus should be poncirus.As i wrote above, in most of the cases in root cuttings L1 will be replaced by L3 cells that are very invasive, but it could be also be formed by the cells from the former L2 that are present in the roots.
L2 : Seeds are from F2. As Prague seems to carry few seeds, it would lead to S2 = satsuma. Seedlings should be pure sastuma.Sylvain demonstrated that fruits and seedlings are pure satsuma
Also L2 + L3 gives leaf form, so if both L2 and L3 where poncirus, i guess leaves would be trifoliate.
I don't know, I wonder if the Chinese Orange could be partly descended from C. indica, which can still be found growing in the wild in Northeastern India. I'm also thinking that Meyer lemon has a lot less C. maxima in its ancestry (if any) than Orange.Both statements have no experimental justification and are misleading.
I'd be really interested in citrus hybrids that didn't have any mandarin in their ancestry, since virtually all citrus hybrids are descended from mandarin.
Thank you Ilya11, this is helpful information. I have recently bought two valentines and it would be sad not to get them ripening because of temperature or sunshine. May I ask how you keep your valentine in winter? I'm bringing them all in with artificial light and temps between low 60's at night and depending of sunshine ( one east and one south window in that room) temp can go to 78 or so. If I would need it to go 83 or higher, I would need to put either a heater in that room or get the trees in the kitchen where it will be warmer during the day.I am trying to keep it as much as I can outside. In the winter it is close to the door of my garage and unheated frame backing the South side of the house. It is mounted on the small cart and I am moving it inside only when night temperatures descend to -4C. Inside the garage in the dark it can be kept for around two weeks at temperatures around 8C.
Thank you so much everyone for your answer! I will skip this variety and everything related to pummelos and also grapefruit.Please do not listen to these "negative" opinions; I suspect many od them they are not coming from genuine experience but are kind of post-truth.
nucellular ( true from seeds)Sorry for the slip.
Ilya, that is very interesting, I never heard of that before. I just examined my microscope and since it is an antique one I think I can get up to 60x or maybe 100x.It is working on any higher plant specie. The method is simple and is a part of practical botany courses in many universities.
That makes your method very interesting, except the plant I want to test is not citrus. Do you know wether your method works for other genera as well? I think I may have a tetraploid Pitanga, based on relative leaf size, vigor and growth rate, compared to the rest of the batch of seeds. I would like to verify that using my microscope but I have no idea wether that is feasible or not.
I have the other seedlings to compare the plant with, so maybe your test will already give some results.
Have you ever done this kind of testing yourself? Or could you direct me to more reading on the web on the method you mention? All help is very appreciated.
Thanks!
