A ternary plot of citrus geneology (jlauf.com)

A Persian lime is a cross between a Key lime and a lemon? I never would have guessed that, that's really interesting.

This is cool! I do wish I could search for a specific citrus by name.

Seems to be missing the Etrog? https://en.wikipedia.org/wiki/Citrus_taxonomy#Citrons

Also, the "click to show search results" is cool but fails for "Arizona Citron" in obvious ways.

Now I wish I could try all of these.

Missing kumquats (and calamondins and mandarinquats)

Inheritance is astonishingly more complex than trees, e.g.

Wong et al. (2024) "A general and efficient representation of ancestral recombination graphs" https://doi.org/10.1093/genetics/iyae100

This is very cool, thank you for building it! I remember reading about the mess of citrus genealogy in John McPhee's Oranges (wonderful book).

During lockdown I started growing clementine from seed. One of the interesting details of this genus is polyembryonism: multiple seedlings emerging from one seed. Apparently, one of the seedlings will be a clone of the motherplant and the rest will be the product of pollination/genetic reshuffling. My clementine seeds all had 2 seedlings per seed but other attempts (with lemon I think) yielded 3 or more).

During my reading I came across a lot of contradictory info about the origin of the clementine: some papers say it’s an unknown hybrid, other clearly state it’s a mutation instead of a hybrid. So it’s interesting to read the hybrid parentage in this triangle, stated with confidence.

Couldn't find blood oranges (sanguina in Spanish). Curious to know where they fit.

I recently learned about the fact that Sichuan peppercorns are actually related to citrus, so was looking for where the connection is... As it turns out[1], there is a "citrus family" (Rutaceae[2]) and a citrus genus (Citrus[3], in that family). The Sichuan plant is a member of the family, but not the genus (that would be Zanthoxylum[4]). Confusing!

Also, this is a pretty good page on citrus (both family and genus): https://www.clovegarden.com/ingred/citrus.html

Thanks lovely piece of work.

I couldn't find Yuzu, I guess I could have looked at the source JSON file, worked out the co-ordinates that find it on the chart, if its there.

Yuzu seems to be having a bit of a moment, like pistachio nuts.

Interesting read, and nicely follows last week’s Lunchbox Envy where “Oranges” was the subject. A great podcast if you like food and fun facts.
