Genome-wide association study reveals putative candidate genes in cucumber (Cucumis sativus L.) associated with shoot and root system architecture traits under water stress conditions.

ABSTRACT: Cucumber is a highly preferred salad vegetable, but it is highly sensitive to drought due to its high water requirement. Therefore, the identification of genomic regions will be highly effective in understanding drought-tolerance breeding programs. In our study, an association panel of 86 diverse cucumber breeding lines was used to detect significant marker-trait associations (MTAs) through the Genome-wide Association Study (GWAS). Phenotyping was done under two different stress conditions - water-deficit and PEG-stimulated stress in the hydroponic medium by measuring different shoot and root system architecture-related traits such as Seedling survivability percentage (SSP), Shoot length (SL), Total root length (TRL), Root volume (RV), Root surface area (RSA), Average root diameter (ARD),
