Exploring the genomic landscape of gummy stem blight resistance in watermelon through QTL-Seq.

ABSTRACT:

Background

Watermelon is a nutritionally and economically significant crop in the US and globally. Gummy Stem Blight (GSB), caused by three cryptic Stagonosporopsis species, is one of the most devastating diseases affecting watermelon in the US, impacting most of the plant's above-ground parts. This study aimed to identify key Quantitative Trait Variants (QTVs) that include SNPs and In/Dels associated with GSB resistance in selfed derivatives of advanced multicross interspecific derivatives population derived from intercrosses between the most resistant lines of Citrullus amarus and highly susceptible cultivars of Citrullus lanatus.

Results

Resistant and susceptible bulks were created by combining equimolar DNA concentrations from 30 extremely resistant derivatives and 30 ex
