Fusarium wilt is a serious disease that causes damping-off, serious wilt symptoms, or death in melon. The aim of this study wasto evaluate the resistance of melon germplasm to Fusarium wilt and select promising disease-resistant accessions for further applications. Resistanceto Fusarium wilt was examined in 216 melon germplasms by the root-dipping inoculation method with Fusarium oxysporum f. sp. melonis fungalisolate KACC43206 (race 2). Inoculated seedlings were incubated for four weeks and assessed for disease symptoms using indices ranging fromindex 1 (no symptoms) to 5 (plant wither). A total of 34 accessions showed a disease index < 2.0. Disease indices of 10 accessions were 1.0four weeks after inoculation. The resistant accessions of melon are expected to help in breeding commercial varieties with Fusarium wilt resistance.
