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. _________________ Wal-Mart a great place to buy cheap plastic crap ! http://walmartwatch.com/ ...

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. _________________ Wal-Mart a great place to buy cheap plastic crap ! http://walmartwatch.com/ ...

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. _________________ Wal-Mart a great place to buy cheap plastic crap ! http://walmartwatch.com/ ...

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
