Abstract

Afield

test was established to determine the genetic inheritance

pattern for fruit soluble solids (measured as brix percentage

of the flesh) between three inbred papaya lines and their three

possible hybrids. The parental lines examineddiffered

significantly for this characteristic. It was established that

high levels of sugars are dominant to low levels. It is

concluded that a great potential exists to exploit this

dominant pattern of inheritance since it opens the possibility

of using inbred lines of good agronomic characteristics but

with low fruit flesh sugar content in the making of

commercial hybrids. The possible underlying mechanisms

that determine this character are discussed for this species.
