Construction of a molecular map for melon ( L.) based on SRAP

Abstract

A molecular map of melon (Cucumis melo L.) was constructed with SRAP (Sequence-Related Amplified Polymorphism) markers using a population consisting of 114 F₂ individuals derived from the cross of 4G21 (C. melo var. chinensis) and 3A832 (C. melo var. saccherinus). Twenty-nine primer pairs were used and 187 polymorphic loci were produced. The map consists of 12 linkage groups that include 152 genetic markers and cover 2077.1 cM with an average genetic distance of 13.67 cM. Every linkage group has 6–32 genetic markers with average genetic distance of 9.72–19.19 cM. The length of linkage group is 85.3–496.1 cM.
