陆地棉每瓤种籽粒数一般为7—9粒。同一棉瓤中籽位不同其籽棉经济性状也有不同。中外的棉花科技工作者曾对纤维长度、纤维分布的疏密、衣分、籽重及纤维重、纤维撚曲数和不孕籽等进行过专门的研究,其中有的结果较不一致。本研究的目的在于进一步探明陆地棉棉瓤中不同籽位经济性状的差异,为棉花育种在考种取样时提供依据。
Upland cotton grains per seed is generally 7-9. The same cotton 瓤 seed in different economic characteristics of its seed cotton are also different. Chinese and foreign cotton science and technology workers have conducted a special study of fiber length, fiber density distribution, clothing points, seed weight and fiber weight, number of fiber twisting and infertility, etc., some of which are less consistent. The purpose of this study is to further explore the differences in economic traits of cotton seed cotton in different cotton fields to provide the basis for cotton breeding in the test sample sampling.
