Correlation analysis of GhAOC and fiber quality was performed using SNP information for the GhAOC copy in the D-subgenome of the ((TM-1×Hai7124)×TM-1) inter-specific BC1 mapping population, along with fiber quality phenotypic data collected over 4 yr for the TM-1,
Hai7124 and ((TM-1×Hai 7124)×TM-1) BC1S1 pedigrees. This analysis strongly indicated that GhAOC was significantly correlated with fiber strength (P=0.014).
