我国目前生产上种植的棉花主要品种,在棉属分类上,都是从陆地棉中,经过人工选择、杂交和培育而成的。由于遗传种质所限,不易选出具有综合性状或突破类型的棉花新品种。随着四化建设的发展和人民生活水平的提高,今后对棉花品种工作将提出更高的要求,不仅要求高产稳产,而且要具有适合机械化栽培的特性;也要求棉纤维品质优良,适合作高档棉纺织品和
The main cultivars of cotton planted in our country nowadays are all made from G. hirsutum under artificial selection, crossbreeding and cultivation in the genus Gossypium. Due to the limitation of genetic germplasm, it is not easy to choose a new cotton variety with integrated trait or breakthrough type. With the development of the four modernizations and improvement of people’s living standard, higher requirements will be put forward on the cotton variety work in the future, which not only requires high and stable yield but also has characteristics suitable for mechanized cultivation; and also requires that the quality of the cotton fiber is good and suitable for high-grade Cotton textile and
