Fig. 6From: Association mapping and domestication analysis to dissect genetic improvement process of upland cotton yield-related traits in ChinaThe effects of different alleles of the major loci (R2 ≥ 3.0) and the favorable allele frequency trends in the four breeding stages. The phenotypic statistics of different alleles of NAU2671, NAU3774, MON-CGR6356, NAU3377, MON-CGR5113, NAU2095, HAU4022, and HAU1434 locus was shown in a-i (left chart). And the favorable allele frequency trends in the four breeding stages are shown in a-i (right chart)Back to article page
