23个陆地棉育种材料的产量及品质性状的差异分析

Difference Analysis of 23 Land Cotton Breeding Material's Production and Quality Traits

采用Duncan新复极差法,针对23个棉花品种(系)的性状和产量进行了综合分析。结果表明:11-18和11-16的纤维品质较好,但其籽棉产量、皮棉产量、单株成铃数都不高,可作为备选育种材料;11-11籽棉产量和皮棉产量均最高,但是断裂比强度较低,需要通过改良才能在生产上应用;11-9和11-10纤维品质较好,其他性状也表现良好,可直接利用。

By using method of Duncan, we focused on yield characters and comprehensive analysis of 23 cotton varieties （strains）. The results indicate： 11 - 18 and 11 - 16＇ s fiber quality are better, but their seed cotton yield, lint yield and the boll number is not high, they become optional breeding materials ; 11 - 11 is the highest in seed cotton yield and lint yield, but fibre Strength is lower, it applied by the improvement in production; 11 -9 and 11 -l O＇s fiber quality are better, other properties have excellent performance, they can be used directly.
