I have grown quite a few varieties and sampled over 20 additional types. Grit free, low latex, precocious and heavy bearing are qualities to go for. The varietal trials at the kamerunga Research Station ranked many types quite poorly and I recall ponderosa and brown sugar were examples of this. Sawo Manila was one of the higher ranked types. On the basis of the glowing performance of Krasuey I planted 2 along with tropical, C 56, sawo manila and 2 others about 20 years ago. I chopped all out and kept the sawo manila and 2 krasueys. In time I also removed the sawo manila. The krasueys being heaving bearing and ever bearing with high quality fruit were so far ahead it was surprising. I get massive crops and year round fruit that is of high quality. If you can get a true krasuey you won't be disappointed.
