育种目标正确与否,决定着育种成败。对海岛棉纤维品质的选育,只有深入了解世界海岛棉的纤维品质及其发展趋向,才能正确制定出育种目标,从而集中力量,攻克难关,育出满足纺织工业需要的新品种。 一、世界海岛棉的纤维品质及其发展趋向 海岛棉(俗称长绒棉)分布于非洲的埃及、苏丹、摩洛哥,苏联的土库曼、塔吉克和乌兹别克的南部,美国西部的亚利桑那州和得克萨斯州,还有我国新疆的塔里木盆地和吐鲁番盆地。其中,埃及和苏联是主要生产国,年产量各约1000万担。 Breeding goals correct or not, determines the success or failure of breeding. Only when we know the fiber quality and development trend of island cotton in the world can the breeding target be correctly set so as to concentrate on and overcome the difficulties and breed new varieties to meet the needs of the textile industry. First, the world’s island cotton fiber quality and its development trend Island cotton (commonly known as long-staple cotton) are distributed in Africa, Egypt, Sudan, Morocco, the Soviet Union’s Turkmenistan, Tajik and Uzbekistan’s southern, western United States, Arizona and Texas There are China’s Tarim Basin and Turpan Basin in Xinjiang. Among them, Egypt and the Soviet Union are the major producing countries with annual output of about 10 million.
