美国从70年代就开始彩色棉花的遗传育种工作,现已培育出五彩缤纷的各种彩色棉花,主要有浅蓝色、粉红色、淡黄色与浅褐色等,但因色素遗传不稳定和变异等多种原因,至今尚未形成品系和品种,近10年来,加利福尼亚州的研究人员曾引进中美州种植的各种彩色短纤维棉花与本地长纤维棉花杂交,已培育出长纤维彩色棉花,主要颜色有深棕色、墨绿色和红色等。 Since the 1970s, the United States has started to carry out the genetic breeding of colored cotton. Now it has developed a variety of colorful cottons of various colors, mainly light blue, pink, light yellow and light brown, but due to the genetic instability and variation of pigment For some reason, no strains and varieties have been formed yet. In the past 10 years, researchers in California have introduced various colored staple cotton grown in Central America to cross the native long-fiber cotton and have grown long-staple colored cotton with the main colors of Dark brown, dark green and red and so on.
