CucCAP scientists genetically map novel sources of resistance to cucurbit downy mildew in watermelon

Watermelon crops are increasingly threatened by infection by cucurbit downy mildew. While there are limited sources of disease resistance within cultivated watermelon, Citrullus amarus can be a valuable source of resistances. CucCAP scientists performed disease resistance screening and whole genome resequencing of 122 C. amarus accessions.  Genome wide association analysis of these materials identified several marker-trait associations and candidate genes, providing potential resources for genomics-assisted breeding for resistance to CDM in watermelon.
