Hi Soren,
I sent you some seeds and met you in Kampala maybe 15 years ago.
I have a negative view of X-77. It is relatively disease resistant in Hawaii and productive but not especially tasty. I think the flavor you object to is much less prevalent in the “red-fleshed” varieties. We grow “Eksotika”. It’s a cross between “Subang 6”, a large Malaysian papaya and the Hawaiian “Sunrise”solo. It is intermediate in size, cylindrical, has quite firm flesh, and very good eating quality. It’s disease resistant under our wet conditions. I think the Malaysian Department of Agriculture bred an “Eksotika II” but I haven’t tried that.
Perhaps you’ll want to trial these varieties, and Sunrise, Holland, Red Lady, etc, to see how they perform under your conditions and which might be favored in the marketplace.
If you’d like to try it, I can send you “Eksotika” seed when we return home next week.
Aloha,
Steph
