In this study, LAMP markers linked to shelf-life in melon (Cucumis melo L.) were developed by converting a cleaved amplified polymorphic sequences (CAPS) marker (C2). The CAPS-PCR fragments from the long-shelf-life melon (O?3) and short-shelf-life melon (Nat-2) were cloned and sequenced to construct LAMP primers. A single nucleotide polymorphism (SNP) was identified between O?3 and Nat-2. LAMP primers were designed to detect the SNP. In the LAMP reaction to detect long-shelf-life melon, the turbidity of the templates using O?3, F1, homozygous long-shelf-life F2 lines and heterozygous long-shelf-life F2 lines started to increase after 40 min. In contrast, the turbidity of Nat-2 and homozygous short-shelf-life F2 lines did not increase even after 90 min. In the LAMP reaction to detect short-shelf-life melon, the turbidity of the templates using Nat-2, F1, homozygous short-shelf-life F2 lines and heterozygous long-shelf-life F2 lines started to increase after 40 min. But the turbidity of O?3 and homozygous long-shelf-life F2 lines did not increase after 90 min. This attests to the high reliability and usefulness of LAMP for marker-assisted selection.
