()
摘要:
1986年在安徽省不同棉区,试验比较了8个棉花品种(品系)的产量表现和纤维品质,并对其进行相关分析,结果表明:徐州553在8个品种中的丰产优质性表现较好。各品种皮棉产量及其构成因素与纤维品质之间,仅纤维长度与产量表现显著正相关。本文还讨论了如何实现棉花高、稳、优的问题,提出了安徽省不同棉区棉花良种布局的建议。

STUDIES ON THE LINT YIELD AND FIBER QUALITY OF EIGHT COTTON VARIETIES
()
Abstract:
Comparative test of yield and fiber quality of eight varieties (strains) andtheir correlation analysis were Carried out in different regions of;Anhuiprovince during 1986. The results obtained show that Xuzhou-553 was betterthan the others. All characteristics of fiber quality were positively or negativelycorrelated with the lint yield as well as components of yield but not significantly,except that the fiber length was positively correlated with lint yield at significantlevel. The questions of stable high yield and fine quality of cotton arediscussed, and the suggestion of rational distribution of good cultivars indifferent cotton regions of An Hui province are also given in this paper.
