850FL, you have a valid question on this category. I thought about these issues as well, then decided well since UCR, CCPP budwood program, has an extensive experience/research of the mandarin in their budwood online order store, I could use their same category.
So, I say we should follow their lead in what variety can be considered in this category as "Mandarin" for the World's Record. I'm sure Guinness has their own consultant that they will use to determine which variety can be entered for this Mandarin category if they ever make one.
Here's UCR CCPP list as of 3/24/21 so it looks good to me and Tangors and Clementines are in this list. No testing is necessary if you enter one from my copied list from CCPP budwood offering.
What do you think, do you agree ?
Here's the UCR link
