Not as far as I know. So many subsequent studies done on the difference in pH based on variety seem to continue to find that they all fall within a very narrow band of pH. The significance of the difference is considered scientifically minimal and is so easily affected by the soil pH where grown that it isn't considered reliable from a scientific POV. Korney's chart was Korney's soil. :)

You can Google up references to several different studies but most cover only the very common varieties. I couldn't find any references to either of those varieties.
