不同棉花杂交种在天山北坡地区的表现及比较研究

[目的]比较分析不同棉花(Gossypium hirsutum L.)杂交种在天山北坡地区的表现。[方法]针对新疆10个主要外引棉花杂交品种的生育期、产量、衣分、纤维强度、马克隆值、纤维整齐度、比强度等主要经济性状与当地品种新陆早13号进行分析和比较。[结果]10个品种的生育期均比对照长,但均属早熟。鲁棉研24(F1)、标记抗虫杂交棉超级1号和标杂A1产量较高,品质也较好,但比强度低于对照;中科898、鲁RH-1(F1)、W8225(F1)、冀丰197、新乡中科59、新乡中科58和新乡中科60在产量上明显低于对照,品质上新乡中科59和新乡中科60优于对照,其他几个品种在品质上与对照相比也无明显优势。[结论]该研究可为今后一段时间内天山北坡地区棉花的科学引种以及育种提供理论依据。

Study on Performance and Comparison of Different Cotton(Gossypium hirsutum L.) Hybrid Varieties in Northern Xinjiang

[Objective] The aim was to compare and analyze the performance of different cotton hybrid varieties in Northern Xinjiang. [Meth- od] Ten outside cotton hybrid varieties were compared with local land cotton variety Xinluzao No. 13 in their sowing time, production yield, length, fiber strength, micron, ginned cotton, gin rate and other major economic traits. [ Result ] The results showed that the sowing time of the ten varieties were much longer than that of the Xinluzao No. 13. Compared with the Xinluzao No. 13, Lumianyan 24（ F1 ）, mark of pest-re- sistant hybrid cotton super 1 and mark of pest-resistant hybrid cotton A1 had higher yield, better quality, but their fiber strength were lower. The yield of Zhongke 898, Lu RH-1 （ F1 ）, Jifeng 197, Xinxiang zhongke 59, Xinxiangzhongke 58 and Xinxiangzhongke 60 were lower than that of the Xinluzao No. 13, among the six varieties, only Xinxiangzhongke 59 and Xinxiangzhongke had better quality, while the others had no significant superiority. [ Conclusion] The study provides a theoretic basis for cotton＇s scientifical introduction and breeding work in Northern Xinjiang during a period in future.
