摘　　要：对“八五”与“九五”刊于《中国棉花》我国自育的163个各种类型棉花品种的纤维品质进行比较分析,结果表明:“八五”育成的74个品种主体长度平均30.34mm,2.5％跨长29.31mm,“九五”育成的89个品种2.5％跨长平均29.37mm,“九五”与“八五”相比纤维长度没有显著变化。麦克隆值分别为4.28和4.45,“九五”比“八五”提高0.24,即纤维略变粗。比强分别为20.53cN·tex^(-1)(ICC校准)和21.49cN·tex^(-1),“九五”提高了0.67cN·tex^(-1)。新疆和长江棉区育成品种的纤维品质好于其他棉区。方差分析表明,仅有长江棉区中熟品种比强“九五”较“八五”提高达显著水平。应加强纤维长度在31mm以上,比强在25cN·tex^(-1)以上品种的高品质育种工作。Data from 163 varieties published in 《China Cotton》were analyzed to estimate the fiber quality improvement between the Eighth-Five-Year Plan (199～1995 ) and the Ninth-Five-Year Plan (1996～2001). The main results showed, 1)74 varieties bred during the Eighth -Five-Year Plan , mean of 2. 5% length is 29. 31 mm, Micronaire value is 4. 28, strength is 20. 53 cN·tex-1 ; While 89 varieties developed during the Ninth-Five-Year Plan ( 1996 ～ 2001 ) , correspondingly data is 29. 37mm ,4. 45 and 21. 49cN · tex-1. Micronaire value increased by 0. 24, while fiber strength increased by 0. 67 cN · tex-1, 2) Varieties bred in Xinjiang Region and Changjiang Region have better fiber quality than other regions. Fiber strength in Changjiang Region increased significant at 0. 05 level. 3) Although some varieties with better quality had been bred out, most varieties with fiber length less than 31mm ,fiber strength less than 25cN · tex-1. So it is urgent to improve the fiber quality.
