Abstract

Anthracnose is a foliar disease affecting all over-ground parts of Cucurbitaceae species including watermelon. When watermelon plant is infected, the pathogen causes lesions and necrosis on leaf and fruit, and reduces the fruit quality and yield as well. The relationship between resistance to anthracnose and morphological traits of watermelon are investigated in this study. Results indicated that, a total of six accessions showed a disease index ≤ 2.0. All the accessions exhibiting anthracnose resistance were collected from Africa. One accession belonged to was C. lanatus species and five were C. mucosopermus. Disease index (DI) was significantly correlated with leaf length and leaf width, size of pistil scar and soluble solids content. The germplasms were divided into three groups based on principle component analysis. Accessions in group 2 showed resistance to anthracnose. Their traits showed small leaf, small pistil scar and low soluble solids content.
