This study aimed to select resistant inbred lines against anthracnose (Colletotrichum orbiculare) in watermelon (Citrullus lanatus). Based on the screening procedures, ‘AU-Producer’ with resistance to anthracnose was selected from the evaluated germplasm. We selected two high quality inbred lines, ‘920532’ and ‘920533’, as recurrent parents. Initial crosses, backcrossing, and disease screening programs were followed by the selection of disease resistant seedlings. As a result of these procedures, anthracnose resistant No. 1, 2, 3, 4, 5, and 6 were selected for high quality and showing resistance to anthracnose. Selected inbred lines of watermelon produced those fruits of red flesh with the size from medium to large as the mean fruit weight of 5.3 to 6.8 ㎏. Those fruits had the characteristics with the soluble solids content of 9.6 to 11.3°Bx and clear stripes on skin. The achievement of this experiment could contribute the possible practical applications on providing the resistant parents in the breeding program for F₁ cultivar of watermelon with the resistance to anthracnose.
