Mangoes seeds that breed true.

[Phoenix From The Ashes]

Hi,

   I recently saw a YouTube video with George Zill and he said that Nam Doc Mai mango seeds will
produce replicas of the mother plant. I’m curious why some mango seeds are “monozygotic” and some are not? Can anyone explain in layman’s terms?

Some mangoes breed true whilst others don't due to the presence of polyembryonic seeds, which is governed by a single dominant gene. Both polyembryonic seeds and mono-embryonic seeds contain the zygote or 'child' resulting from pollination, but polyembryonic seeds also contain a number of clonal embryos of the mother plant. When you plant a polyembryonic seed, you will get multiple seedlings, one of which is the zygote (which won't breed true), the rest are clones of the mother tree (which will).

Actually, any seed produced by "breeding", meaning by plant sex/pollination, is not a true copy of the mother tree.

Only those extra embyos produced in polyembionic seeds are true copies of the mother tree/seed parent.  They are produced by cloning;  they are not bred.

So I can plant the seed of M4 and Orange Sherbet And it will be a copy of the mother plant or similar variation?

Thanks Ed

Do you have a reliable way to know which seedlings are clones?

Visual inspection relies on having many young plants of the same polyembrionic seed source to look at.  One can soon figure out what the consistent characteristics of the majority of plants are---the majority are the clones.  One can then remove the "off-types", if one wants the clones;  or, one can remove the clones, if one wants to grow out the "off-types"/ sexualy-produced seedlings, to see what they will produce.

I agree with Har.

Additionally, from the data I’ve read and from members that post on other threads regarding Polyembryonic mango varieties, if you plant a NDM mango seed, all the seedlings are not guaranteed to be clones. One or more of the seedlings can be zygotic.

I used to believe that a Polyembryonic mango seed could only produce one zygotic seedling but according to a paper I posted on another thread, that is not necessarily true.
