Figure 2From: Quantitative trait loci analysis of fiber quality traits using a random-mated recombinant inbred population in Upland cotton (Gossypium hirsutum L.)The effect of marker selection on fiber bundle strength (STR). Based on the genotypes of seven markers (QTLs), the 275 RILs of Set 2 (panel A) and all 550 RILs (panel B) were divided into two groups: 1) RILs containing 3 or more favorable alleles (Selected in red) and 2) the remaining RILs (Non-selected in black). The mean STR values of the selected and non-selected RILs were shown in red and black circle, respectively. The STR difference between the two groups was significant at p < 0.001.
