摘　　要：报道2003年至2004年10个引进亚麻品种在云南省8个试验点的纤维产量和品质测定结果。3个国外品种的长麻率、总麻率、纤维产量明显高于国内品种；方差分析显示，不同地点间、不同品种间纤维产量差异显著。10个亚麻品种的平均分裂度变幅为344～407公支，平均断裂强力变幅为200～248N，平均可桡度介于49．6～56．6mm；同一品质指标在不同试点的变幅较大。方差分析结果表明，正麻品种间的纤维品质差异不显著，地点间的纤维品质差异显著。The fiber yield and quality of 10 introduced flax varieties at 8 counties of Yunnan province were analysed in 21303 - 2004,The long fiber content, total fiber content and fiber yield of 3 foreign varieties were higher than those of home varieties. The variation analysis results showed that there were significant differences among districts and varieties in fiber yield.The fiber thinness of 10 varieties averaged for 344 - 407 m/g, fiber firmness for 200 - 248 N, and fiber flexibility for 49.6 - 56.6 rnm. Fiber qualities in different experimental sites varied more than that in varieties. According to the variation analysis results of fiber quality, there were no remarkable differences among varieties, but remarkable differences were found among districts.
