Detection of QTLs and QTL-environment interactions for fruit branch number in Upland cotton (Gossypium hirsutum L.) using a restricted two-stage multi-locus genome-wide association study.

Abstract excerpt

BACKGROUND: Fruit branch number (FBN) is an important architectural trait of Upland cotton (Gossypium hirsutum L.). In this study, FBN was investigated in 340 Upland cotton accessions across five environments. The restricted two-stage multi-locus genome-wide association study was employed for the first time to dissect the genetic architecture of FBN. RESULTS: A total of 37,010 high-quality single-nucleotide...
