Seems like the new bit of information is at the end of the article:
> Addendum, Jan. 16th, 2024
> Reports in the Washington Post (long text) and at the “Genetic Literacy Project” (short text) report on a huge setback in the “American Chestnut Project”.
> Apparently seeds had been mixed up or mislabelled before planting. Instead of Darling 58, a mixture of Darling 54 and Darling 58 was planted! The young Darling 54 trees are less robust, have slower growth, die more often and also seem to have a lower tolerance to the fungus.
