of a random mating system between plants of the same accession.
Only papaya inbred lines L12-01.2, L12-01.5, and L12-02.5 were
the result of a cross (carried out in field conditions) between the
papaya hybrid Calimosa and the common papaya. Therefore, the
major source of genetic variation in these papaya inbred lines is
derived from the choice of founder parental. This is the primary
source of genetic variation between these lines, and therefore, the
regions between recombination breakpoints on the chromosomes
can be used as a measure of genetic diversity. Thus,the high level of
diversity for alltraits evaluated shows thatthe accession conserved
at the active papaya germplasm bank can be used to develop new
papaya cultivars and hybrids successfully.
