멜론과 참외의 국내 소비 시장이 확대됨에 따라 다양한 F1 품종이 개발되고 있다. 멜론과 참외의 F1 품종의 순도를 검정하기 위해 포장재배 등의 순도검정법이 이용되고 있으나 시간과 노력이 매우 많이 소요되기 때문에 분자마커를 이용한 순도검정법의 개발이 필요하다. 본 연구에서는 멜론의 EST 염기정보로부터 30개의 SNP 프라이머 조합을 고안하여 멜론과 참외의 순도 검정을 위한 HRM분석방법을 개발하였다. 멜론 두 품종과 참외 한 품종의 양친 사이에 HR
Field screening method has been commonly used for purity test of F1 hybrid seeds in melon and oriental melon. However, as this method takes a lot of time and cost, molecular marker-based purity test is necessary. To develop molecular markers for purity test, thirty pairs of SNP (single nucleotide polymorphism) primers were obtained from melon EST sequences, and 10 polymorphic markers showing HRM (high resolution melting) polymorphisms between parents of two melon cultivars and one oriental melon cultivar were selected. Blind tests were performed to validate usefulness of the selected markers for purity test. Blind test results showed that HRM genotypes were matched with the expected identity of individual sample, F₁ hybrid, male or female parents. Three HRM-based SNP markers were converted to CAPS markers for general use which is favor to breeders. We expect that SNP markers developed in this study will be useful for purity test of F₁ hybrid seeds in melon and oriental melon.
