thanks Raul,
yes this is the same as what they call Easy peel , or chewy.
the Vietnamese name is "Na Dai", so I use that name.
it's one of my favorite sugar apples, because it reminds me more of an atemoya in terms of texture being like geffner, or PPC.
it has some tartness and lots of sugar....low seed count.
fruits very early from seed, about 2-3 yrs, and can stay in a pot for a long time...doesn't require hand pollination.
