近二三十年来,随着遗传学的发展和育种工作的需要,国内外在棉花性状的遗传研究中,除研究质量性状的遗传外,对一些重要的经济性状如产量、纤维品质性状等的遗传,也进行了广泛的研究,一致认为这些性状都是由多基因控制的数量性状。由于数量性状容易受环境的影响,所以各试验分析结果,往往因材料、地点、年份及分析方法等不同而不尽一致。故欲真正探明棉花主要经济性状的遗传变异特点,有赖于大量试验资料的累积和分析。 In the recent two decades and more, with the development of genetics and the need of breeding work, in the genetic studies of cotton traits both at home and abroad, in addition to studying the inheritance of quality traits, some important economic traits such as yield, fiber quality traits Genetic, also conducted extensive research, agreed that these traits are quantitative traits controlled by multiple genes. Because quantitative traits are easily influenced by the environment, the results of each test analysis often differ according to material, location, year, and analytical method. Therefore, to truly prove the main economic traits of cotton genetic variation, depends on the accumulation and analysis of a large number of experimental data.
