摘要
为了探讨海岛析产量性状与品质性状的相互关系,通过测定海岛棉新海3号×吉扎82的181个F2∶3家系的7个产量性状和7个纤维品质性状,利用统计分析软件对其进行典型相关分析和通径分析,以明确其产量性状与品质性状之间的相互关系。结果表明:育种中选择高衣分的材料不仅可以提高皮棉产量,而且可以间接地增加纤维上半部平均长度、纤维伸长率、比强度,降低马克隆值,这有利于主要纤维品质性状的提高,但会降低纤维整齐度。产量各性状对皮棉产量的通径分析结果可知,无论是直接通经系数还是最后的净效应值,其作用均是单株铃数>衣分>单铃重,偏重单株铃数和衣分的选择,将有利于海岛棉产量的提高。品质性状的通径分析结果可见,比强度、整齐度和长度是影响纤维品质的最重要因素。
By discussing the correlation of sea-island cotton yield and quality characters,measuring seven yield characters and seven fiber quality characters derived from sea-island xinhai 3 and jiza 82,using the statistical analysis software,doing canonical correlation analysis and the restoring menstrual analysis of that,the correlation factors of the yield characters and fiber quality characters were nailed down.The results showed that when material with high lint percentage is selected,not only the lint yield but also the fiber length,fiber elongation,fiber strength increase.In the meantime,it could include the micronaire value,that can help improve fiber quality.But at the same time it could decrease fiber length uniformity.The restoring menstrual analysis of yield characters and the lint yield indicate that whatever the direct path coefficient or the net domino offect value,the effect are all boll numbers〉lint percentage〉boll weight.If particular stress is laid on selecting the boll numbers and lint percentage,yield quality can improve.The restoring menstrual analysis of fiber quality traits and the lint yield showed that fiber strength,fiber length uniformity,and fiber length is the leading factor affecting fiber quality.
