ok, if you like good tasting citrus, the ones I still have because they taste good are the Valentine, Cocktail, Thong Dee (excellent), Melogold. People keep mentioning the Sarawak/Tahitian pummelo is good, but I didn't think so and I top worked my tree with other better tasting varieties.
Now the best pomelos I have are seedling varieties and they are better tasting than majority of the pomelos from UCR except for the Thong Dee.
But, if you like kumquats, one of the best tasting to me was the Indio Mandarinquat (VI 335). I ate fruits from the UCR research field and it was excellent, better than the Nagami kumquat since it is a much larger fruit and juicy and sweeter. But, I do have the seedless Nagami and it is nice since you can pop the entire fruit in your mouth and eat it all.
