Google search did not yield results, do you have an article or something in hand that might help? where did you hear about this havaguski
I now there are no google results..
Got it as a small grafted plant from a czech friend by mistake.
i havent asked in that time anymore about it, just that it is mandarin.
I got first fruit last year smaller easy to peel, seedless, juicy with very nice taste.. i want to check back and get more info on its origin, unfortunaltely lost contact with the source.. i asked few other citrus growers in czech/slovakia, but no one knows
