Fine-mapping and candidate gene analysis of qFF3.1 conferring fruit firmness in a modern tomato variety
Fine-mapping and candidate gene analysis of qFF3.1 conferring fruit firmness in a modern tomato variety
Tomato fruit firmness is a critical determinant of postharvest quality, dictating storage, ultimate shelf life, and market value. While previous research on tomato fruit firmness has largely confined to wild or heirloom accessions, the genetic basis underlying this trait in modern elite breeding lines remains largely unexplored. In this study, we dissect the genetic architecture of fruit firmness using a recombinant inbred line (RIL) population derived from a cross between the modern inbred line CF-1 and the conventional cultivar Moneymaker.
