I was aware that Clementines are zygotic, and plentiful at certain times of the year, so I intend to extract seeds from grocery-purchased fruits when winter comes again. But Clementines are known to have a certain amount of pomelo admixture, and most of the 'pure' species mandarins are mostly or entirely nucellar.
Then I learned that Kishu mandarins entirely zygotic, and I became very excited!
Then I discovered that every strain of Kishu that had crossed the Pacific from Japan that I could locate was an entirely seedless strain, probably genetically damaged. So, as tasty as they may be, they're useless for my purposes.
Does anyone know where I could acquire seeds or budwood for the traditional Japanese strains of Kishu? I understand that the Japanese prefer citrus with seeds as a symbol of fertility and vitality.
