Abstract
Two melon varieties (85-1 and B717), being significant differences in grafting affinity with the pumpkin rootstock “a
strong man”, were used as parents to construct F
2:3
populations; molecular markers linked to graft compatibility were identified by
PCR technology based on differential DNA pools in grafting affinity prepared by BSA approach. The results showed that 382 pairs of
primers with polymorphism in two melon parents were screened from 750 pairs of SSR, SRAP, AFLP primers, which had published
in the
cucurbitaceae
genetic linkage map. There are 9 pairs of primers that can respectively amplified different fragments in
differential DNA pools in grafting affinity, and these different markers were further used to amplify F
2
population to calculate the
genetic linkage distance between the marker and the trait of grafting affinity. The distance of markers of CMN-0616 and M103 both
linked to grafting affinity with the genetic were 17.6 cm and 9.3 cm respectively. These two pairs of primers would be expected to be
as assist markers to identify grafting affinity of the melon in order to distinguish varieties with different grafting affinity at the level
of molecular background which might provide the reference for developing grafted melon scion in breeding program.
