If the tree is still dormant at the start of April I may have some.

There will be a gaseous carbon reckoning.

Is cherilata different than Painter and Fernandez?

Hi Pau,

Mine is a darker red almost deep purple. It doesn't look like "Painters" but I don't remember where mine came from. This is the first year it fruited and the fruit aren't ripe yet, so we'll see what the flesh looks like.

It came from me, the scion I received from John Painter.

I am with 1rainman.  I NEVER use the self checkout on purpose

I prefer self checkout to a scanner/bagger who smashes my fruit.

As those are all monoembryonic types, I would plant a rootstock now and graft it with one of those types after it's three years old.

My Alphonse flowered way too much, and eventually died back to the ground (planted as a number 7 on Turpentine), Keitt is nearly the same, after repeated years of extreme flowering it is nearly back to a stump (planted as a number 15 on Manila).

I haven't planted Kesar yet, but I suspect it will flower similarly, so a rootstock must be fairly well established to continue growing through the 3-4 flowerings a tree will produce each year in socal.

Are you willing to deal with import restrictions?

Seed molding happens a lot when germinating, the weak seeds particularly succumb, as well as those irradiated and refrigerated.
That tree looks pretty crispy, but if you do a bark scrape test, you may be pleasantly surprised. Damage up top usually weakens a mango tree, but damage to the roots usually kills them ded.

Wow, Thank you for the followup Alex.
I'm eager to regraft it, but with moderate-low vigor, and high propensity to flower, it should definitely be on an established rootstock for So-Cal. I think I have at least one more that's hanging on through the gopher onslaught, looks like it may be grafting size later this year or next year if it lives that long.

Good luck, it's a rare one for sure, with a short season.

So does the shape of the pollinated fruit offer hints as to the pollen used to fertilize the embryo to create that fruit? I think the answer to that question is that it depends on the species.

Weirdly it's not a factor for most fruit except Annona like Cherimoya, where the pollen used in fertilization can affect the shape of the fruit as it develops.

That said, it's not a helpful tool most of the time, and you can use techniques to verify the pollen parent by bagging flowers and removing the pollen of the flower after pollinating, but before the flower enters male stage and the pollen dehisces.

Are you trying to use crossing as a tool to learn more about the variety you obtain pollen of?
Otherwise I don't see the use of this tool, and even if that is the goal it seems that it really only plays a factor in fruit shape if I understood what I've read correctly.

Factors like fruit shape don't necessarily play into the progeny though, it depends on phenotypic inheritance.

Some trait genes are dominant, and will more than likely affect the resultant cross. Others can be reflected partway or blended. Some are recessive and are less likely to be reflected in the cross, and may take multiple generations of selection to be reflected in a cross.

Let's take mango seed polyembryony as an example.
The seed polyembryony is affected by a single gene, and the trait is inherited in a dominant pattern similarly to gender in humans. They aren't referred to as "X" and "Y" due to them not having this characteristic shape, but they do follow a similar pattern, so we can call them "X" and "Y" for demonstrative purposes. Similar to how "X" works for humans, the gene that carries the trait for mango seed monoembryony is inherited recessively. Therefore you can get monoembryonic offspring from polyembryonic parents, and at a ratio of 25% if both parents are polyembryonic, and 50% if one parent is monoembryonic. If both parents are monoembryonic the result of their crossing will yield 100% monoembryonic offspring. This discussion only applies to zygotic seedlings.

For typing mango offspring, this is most helpful for determining the the potential parent of a cross. If you have three mango trees in your yard, in this example a monoembryonic type, a polyembryonic type, and a seedling of the monoembryonic type, and it's assumed that no outcrossing is possible, you may potentially be able to identify the parent of the offspring if it produces fruit with polyembryonic seeds. That said, we don't seem to have any mango "breeders" as such, only mango "selectors," and "selectors" don't select on genotypic traits, but phenotypic, or "expressed" traits. You get a lot of confusion when purported parentage of mango selections are espoused, often leading to forum discussions similar to that you might overhear on daytime television.

You could use vapor barrier or similar sealant to create a non permeable barrier between the soil and the pot. Clay might be the best choice.

The cement will always dissolve as long as the soil is in contact with the surface and is wet.

I see the spider mite damage, but this looks fungal in origin.

Similar symptoms occur from lack of zinc. Did you fertilize this after symptoms appeared, but before the picture?
