Hi,

Can we list true-to-type citrus varieties, that can be grown from seed without requiring a graft/bud?

While writing a message I noticed that I don't have much info on this, I only know that Meyer lemon and Yuzu are true-to-type (if this is true).

Thanks,

Hi MeyerLemon. Most citrus come true from seed. The ones that do not are :

Pumelo
Bearss lime
Clmentine mandarin
Temple tangelo

Most citrus that are Mono-Embryonic do not come true from seed. The exception to the rule is Yuzu.

Hi Laaz,

This is surprising for me.Since now, I always thought that citrus trees always need a graft, except few varieties.

I am searching myself in the forum but can you direct me a related topic with more info?

Thanks,

Almost all sweet oranges, true grapefruit, lemons, limes, pure mandarins (other than King and Clementine), most Tangelos, hybrid tangerines and Tangors (except Temple) come true from seed. Pummelos do not.

Thanks Laaz and Millet,

I noticed that I already have that article in my "read in future when you have some time" folder.I guess it is the time.

Since the day I found this forum, I learned a lot from you, thanks.

Say we will T-bud two rootstocks.Same rootstocks but the buds are taken from 2 different source trees.One source tree is a grafted tree and the other source tree is grown from a seed.Will the buds act same or will there be a difference?

What do you think?

Buds remember their node count, therefore if you take a bud from a young seedling you will still have to wait years for it to fruit. If you take a bud from a mature fruiting tree it will fruit in a year or two.

Tangelo Ugli is monoembryonic, isn't it ?

I have read that Orlando tangelo will come true from seed, fruit in about 4 years, and do ok on it's own roots. There are many citrus that come true from seed, but that do not do well on their own roots. That has to be a consideration when growing seedlings, unless you plan to graft it to a good rootstock as soon as it begins growing.

According to Malcolm Manners the Ugli does not come true from seed & yes Ugli is monoembryonic.

Thank you Laaz. All my seeds of ugli were monoembryonic, but I wasn't absolutly sure.

Notice that the first assumption here -- that Meyer itself is true-to-type, is not true. That's why it took so long for anyone to come up with tristeza-virus-free Meyer -- it could not be cleaned up through seed.

Thanks for the new replies and the correction on Meyer Lemon.

I am just not sure that if I can understand if a seed is monoembryonic or polyembryonic.Can you direct me to a photo?

If species is polyembryonic
, of course you will see 2 or more stems coming out of the seed...but not everytime : If for exemple only one of the embryons has survived,(probably nucelar), you will have a single plant.

In this picture, you can see one stem, but also a second embryon trying to go out from the seed. He won't survive
