The complete trait data are only included for the traits associated with the identified SNPs; 1 Least square means within columns that do not share a lower-case superscript letter (a, b, c, d, e, f, g) are different, p < 0.05; MFD, means mean fiber diameter; FW, fleece weight; FDSD, standard deviation of the mean fiber diameter; CVFD, coefficient of variation of the mean fiber diameter; 2 p value was evaluated based on threshold gene-wide (p < 4.55 × 10−3 = 0.05/11) using Bonferroni correction; NE stands for not estimable.
