PRELIMINARY EVIDENCE OF A GENETIC CAUSE FOR THE FLORAL ABNORMALITIES IN SOME OIL PALM RAMETS

RAO, V. *; DONOUGH, C.R.**

ABSTRACT

In some ramets of oil palm clones the normally vestigial gynoecia and androecia of male and female flowers respectively develop abnormally, resulting in floral dysfunction. Such abnormal development has also been observed in the open-pollinated progeny of these ramets. this evidence of, most probably, matroclinal sexual transmission suggests that abnormalities may have arisen from changes to extrachromosomal hereditary determinants during tissue culture.
