【摘要】 以1973-2011年黄河流域棉花品种区域试验参试品种为材料,对皮棉产量(kg·hm-2)、上半部平均长度(mm)、比强度(cN·tex-1)及马克隆值4个主目标性状进行了不同年代或省份的差异分析,结果显示:20世纪80年代和21世纪初育成品种的皮棉产量高,特别是21世纪以来皮棉产量大幅提高,94.8%的品种为≥1200kg·hm-2的高产品种;随着年代的迁移上半部平均长度及比强度均有不同程度的改善,但马克隆值在增大,棉纤维呈逐渐变粗趋势,值得高度重视;从不同省份(单位)育成品种主目标性状的差异来看,山东省育成品种的皮棉产量、上半部平均长度及比强度最高,其次是中棉所、河南省及河北省育成品种,但马克隆值普遍较大,纤维偏粗,江苏省育成品种的皮棉产量相对较低,优点是棉纤维较细。这些可作为棉花品种区域化种植的参考。更多还原

【Abstract】 Based on the varieties joined the Yellow River Valley Regional Test from 1973to 2011 , four main objective characters including lint yield , fiber length , fiber strength and micronaire were analyzed for differences in years or provinces.The results showed that lint yields were higher for varieties bred in 1980sand early 21th century , especially the varieties bred in early 21th century , 94.8% of which were high yield varieties ( the lint yields were above 1200kg · hm -2 ) .The fiber length and strength were improved in certain degree , but the micronaire was increased and the fiber was becoming thicker , which should be cared.According to the four main objective characters , varieties bred in Shandong Province were best in lint yield , fiber length and strength , the next were varieties bred in the Institute of Cotton Research , CAAS , Henan Province and Hebei Province , but the micronaire for all the varieties were higher , and the fiber were thicker.Varieties bred in Jiangsu Province were lower for lint yield but the fiber were thinner.Those results could be referenced by cotton regional planting.更多还原
