Phyllotaxis in the Oil Palm: Application in the Evaluation of pisiferas

Yield differences between and within four segregating familiesof Oil Palm are shown to be highly correlated with differencesin the phyllotaxis index, E.P.I., of the female inflorescences.This association should facilitate prediction of the yield potentialof an effectively sterile segregant palm type known as pisifera,which is used as a male parent in hybrid seed production.
