Abstract

An Ananas comosus variety is provided that forms attractive orange-red oval to cylindrical fruit with relatively flat fruitlets. The fruit is substantially uniformly colored from top to bottom when ripe even in the absence of chemical treatment with a growth regulator. The fruit flesh is golden yellow and substantially homogeneous. When compared to Smooth Cayenne (non-patented in the United States), the fruit flesh in generally sweeter and commonly contains substantially more ascorbic acid. Such higher ascorbic acid content is of nutritional benefit and serves to retard the browning of the flesh. Completely spineless piping leaves are formed. On an infrequent basis peduncle slips are formed that commonly are spaced below the fruit and do not to pose any significant interference. The fruit crown is long, erect, and conical. The fruit yield is generally comparable to that of Smooth Cayenne.
