Citrus General Discussion / Re: Pomelo versus Grapefruit

Mike, here Mabberley can help.
He created a botanical naming system for Citrus, which isn't because of visual differences, he created it according to genetical differences.
Mabberley sorted Citrus because of it's genes. For many horticulturists the system is to difficult, because it creates to much confusion.
For example: Within the Citrus x aurantium group one will find the Sweet Oranges, as the Sour Oranges, but also the Grapefruit.
Mabberley found that the Pomelo - Citrus maxima - is a true species.
Citrus x aurantium is a natural hybrid of Citrus reticulata and Citrus maxima - thus Grapefruit is a natural hybrid of Mandarine with Pomelo.
Those genetical relationships were found by Hogson first published within Citrus Industry Vol. 1 - but the books still used the Tanaka systematics to classify Citrus botanically. It was also published by Albrigo and Davis in their book on Citrus.
In 1997 Mabberley published his analysis and his created botanical system of Citrus classification - and so we can find the parentages for the Grapefruit.
So I think, we won't get any closer als this information
