对 2 3个陆地棉亲本及其形态、产量、品质性状进行对应分析。结果表明 ,构成株型因子的主要性状是株高、果枝台数、果枝长、第一果节长 ;影响单株产量的主要因子是单株铃数 ,其次是衣分和单铃重 ;影响品质的主要因子是 2 5 %跨长、整齐度和马克隆值 ,其次是纤维强度。 2 3个陆地棉材料根据因子得分进行聚类可划分为 7个不同遗传差异的类群。
The corresponding analysis of 23 cotton cultivars and their morphological, yield and quality traits was conducted. The results showed that the main characters of plant type were plant height, number of fruiting branches, fruiting branch length and first fruit node length. The main factors influencing single plant yield were boll number per plant, followed by boll weight and boll weight; The main factor is 25% span length, uniformity and micronaire, followed by fiber strength. 2 3 Upland cotton materials Clustering by factor scores can be divided into seven groups with different genetic differences.
