摘要: 目的 为探讨海岛棉纤维品质与其种子短绒多寡之间的相关关系,提高海岛棉品质育种效率。方法 以218份海岛棉种质资源为供试材料,通过2年纤维品质指标的检测及短绒多寡的调查与分级,分析短绒各分级间纤维品质指标的差异性及纤维品质与短绒多寡的相关性。结果 方差分析表明,各级间除马克隆值差异不大外,其他纤维品质指标随着短绒的增加而增高,且差异呈极显著或显著(P<0.05或P<0.01)水平。Spearman相关系数表明,纤维上半部平均长度、断裂比强度、长度整齐度指数和断裂伸长率分别与短绒级别间呈极显著(P<0.01)正相关,马克隆值与级别间呈显著(P<0.05)负相关。结论 海岛棉纤维品质与其种子短绒多寡间有统计学意义的正相关性,短绒多寡可作为海岛棉纤维品质优劣的参照之一。

Abstract:

[Objective] To investigate the correlation between seed fuzz amount and fiber quality of sea-island cotton and to improve its quality breeding efficiency. [Method] 218 germplasm resources of sea-island cotton were used as tested materials, through two-year detection of its fiber quality traits, investigation and classification of the fuzz. The difference of fiber quality traits of sea-island cotton among each fuzz grade and correlation between amount of seed fuzz and fiber quality of sea-island cotton were analyzed. [Result] Variance analysis showed that other fiber quality traits among different grades increased extremely significant (P < 0.01) or significant (P < 0.05) with fuzz grade (fuzz density) increasing except micronaire. Spearman rank correlation coefficients indicated that upper half mean length, breaking tenacity, uniformity index and breaking elongation were significantly and positively correlated (P < 0.01) with fuzz grades respectively, while micronaire was significantly and negatively correlated (P < 0.05) with fuzz grades. [Conclusion] These results indicate that there is a statistically positive correlation between seed fuzz amount and fiber quality of sea-island cotton (G. barbadense), the seed fuzz amount can be used as a standard for the fiber quality pros and cons of sea-island cotton.
