摘　　要：通过对高产高品质陆地棉渝棉一号选育系952-23与典型的低产低强度陆地棉多基因标记系T586杂交的F1,经多代不同纤维品质重组自交后,对F3与F7纤维的主要品质指标进行了检测,并对检测结果进行了统计分析。结果表明,各项指标的变异系数都比较小,F3与F7白色纤维的长度,绿色纤维的细度相关性显著,即这些性状遗传相对稳定,可进行早代选择。F7与F3的纤维品质相比较,长度指标减小了,但细度和比强有所提高。Two cotton varieties （952-23xT586） 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 FT, 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.
