Interesting paper on plumcot genetics (2023)

pcr-ssr is an industry standard tool which helps real breeders make decisions and like any tool it has capabilities and limitations and pointing out its limitations - I dunno - I think these working breeders and scientists understand those just fine. someday it’ll go away - is already going away - when sequencing is cheaper

For what it’s worth, I have worked with SSR markers, SNPs and full-genome sequences to generate linkage maps and identify loci associated with certain traits in grapes, and all three have been in agreement for the traits I looked at.

With a genome sequence, it’s easy enough to take the SSR marker primers and identify what will get amplified with PCR. I never had a good SSR marker generate off-target products from unexpected chromosomes in high enough quantities to matter (otherwise it would have been discarded earlier).

We have been using SSR markers to identify parent-offspring relationships in grapes for decades. So far, these pedigrees have been fully supported by sequencing data.

Pluots and Asian pears are among my favorite fruits! Nectarines are good, but soft and sweet is not my favorite.

but soft and sweet is not my favorite.

That’s my ticket.

If they have produced an outstanding fruit, who cares about the fine details of its genetics?

Mostly breeders. Largely because knowing the ancestry gives you an educated guess about what traits are likely to show up in the offspring. For strictly eating purposes, you’re right ancestry doesn’t matter.
