Two cotton varieties (952-23×T586) were hybridized, F3 and F7 fiber property indexes were measured, the experimental data were disposed by statistical analysis. the result indicated: the coefficients of variance in each index were small, white fiber length and green fiber fineness in F3 and F7, mean while these characteristics were stable, so it could be screened in early generations. Compared with F3, F7 fiber length index decreased, and F7 fiber fineness and strength indexes increased.
