Abstract
The length of fruit branches significantly influences plant architecture in upland cotton (Gossypium hirsutum L.), which is crucial for optimizing fiber yield and quality. In this study, a comprehensive genome-wide association study was conducted based on whole-genome resequencing data that identified 249 significant SNPs associated with fruit branch length (FBL), forming 79 distinct quantitative trait loci (QTL) regions. Notably, stable QTL regions qFBL-A10-4 and qFBL-D03-17 were identified, harboring key candidate genes such as Ghir_A10G014390 and Ghir_D03G011390. Superior haplotypes of these genes significantly enhance FBL, fiber yield, and quality, offering valuable targets for cotton breeding programs focused on optimizing plant architecture and productivity.
