Association mapping of tomato fruit quality for weight, firmness, brix, and color using GWAS.

ABSTRACT:

Background

Fruit quality traits such as fruit weight, firmness, total soluble solids content, and color strongly influence consumer acceptance, market value, postharvest shelf life, and processing efficiency in tomato. Therefore, these traits are central to breeding programs but remain challenging to dissect due to their polygenic and pleiotropic nature.

Results

We evaluated 167 accessions from the Varitome collection, encompassing Solanum pimpinellifolium, Solanum lycopersicum var. cerasiforme, and Solanum lycopersicum var. lycopersicum. The Varitome collection represents a rich source of genetic and phenotypic diversity, making it a powerful resource for mapping complex traits. Genome-wide association studies (GWAS) were conducted using the FarmCPU and Blink models, utiliz
