棉花纤维含糖量是影响棉花纤维品质和纺纱工艺的一基重要指标.棉纤维含糖量高,不仅影响纤维比强度,而且加重棉花粘性,使纺纱过程中产生缠绕现象,影响纺纱工艺和纱品质量.近年来,棉花科研工作者从多方面探讨棉纤维含糖规律,并从栽培因素和棉花品种等方面提出了解决棉纤维“高糖低强”的一些措施.我们的研究表明,海岛棉纤维含糖量是个遗传性状,受微效多基困控制,通过杂交育种可以有效地降低杂种后代的纤维含糖量.通过五年选育,已获得优质、高产、含糖量低、稳定性好的品系20多个,以及上百个优良单株和株行材料.
Cotton fiber sugar content is an important index of cotton fiber quality and spinning process.Good cotton sugar content is high, not only affects the fiber strength, but also increase the cotton stickiness, so that the spinning process of winding phenomenon, affecting the spinning Technology and yarn quality.In recent years, the researchers of cotton explored the regularity of sugar content in cotton fiber from many aspects and put forward some measures to solve the problem of “high sugar and low sugar content” of cotton fiber from aspects of cultivation factors and varieties of cotton.Our research The results showed that the sugar content of island cotton fiber is a genetic trait controlled by micro-efficiency and multi-base control, which can effectively reduce the fiber sugar content of hybrid offspring through crossbreeding.Through five years of breeding, the quality, yield and sugar content Low, good stability of more than 20 lines, and hundreds of excellent single plant and plant materials.
