| 摘 要： | 目的]研究高品质陆地棉主要农艺性状与单株皮棉产量的关系。方法]于2007年采用田间试验完全随机区组设计,以单株皮棉产量为指标,根据系统聚类中的最小离差平方和法将24个高品质系聚为高、中、低产3大类型,比较3大类型单株皮棉产量和10个农艺性状的差异显著性,对10个农艺性状与单株皮棉产量进行相关分析和逐步回归分析。结果]高、中、低产3大类型在株铃数、衣分、衣指、果节数和生育期等性状上存在显著或极显著差异,高产类型的株铃数、衣分和衣指最大,而果节数和生育期最小（短）。株铃数和铃重与单株皮棉产量呈极显著或显著正相关,果节数与单株皮棉产量呈显著负相关,株铃数、铃重和果节数对高品质陆地棉单株皮棉产量的形成起主要作用。结论]该研究结果对高品质陆地棉品种的选育具有一定的指导作用。

| Abstract: | Objective]The purpose was to study the correlation between main agronomic traits and single plant lint yield in upland cotton with high quality.Method] 24 upland cotton lines with high quality were analyzed for single plant lint yield and 10 agronomic traits in a randomized,complete block at the agriculture experimental station of JXAU,Nanchang,China in 2007.They were divided into three types(high,medium,low yield) based on single plant lint yield by Ward's method.A total of 10 traits of three types were ... |
