由于气候原因，长绒棉只有小部分地区能进行生产，我国只有新疆棉区能种植，但面积小产量低。我国棉花主产区的黄河流域和长江流域，建国初期，虽曾通过引种改良和海陆杂交等方法选育长绒棉品种，未能取得成效。本所于１９８５年通过辐照埃及棉阿须莫尼的干种子并结合常规育种方法，经多年系统选育，培育出一批具有陆地棉的适应性和长相，品质指标达到或略高于我国当前生产的长绒棉的陆地棉型长绒棉突变系。１９９６年将选择的单株材料和优系由省棉花研究中心用ＨＶＩ９００测试，在入选株系中，平均绒长３４７３±１３９ｍｍ，比对照中１２提高５９３ｍｍ。比强度全部在２４ｇ／ｔｅｘ以上，平均为２６７５±１６２ｇ／ｔｅｘ，最高的达３１１ｇ／ｔｅｘ，比对照增强６０５ｇ／ｔｅｘ，且各品质性状相互协调。 Due to climatic reasons, only a small part of the long-staple cotton can be produced in our country, only Xinjiang cotton can be planted, but the area is small and the output is low. In the early stage of the founding of the Yellow River and the Yangtze River valley in the main cotton producing areas of our country, although the breeding of long-staple cotton varieties by means of introducing improvement and cross-breeding by land and sea had failed to achieve any success. The Institute in 1985 through the irradiation of Egyptian cotton acacia dry seeds and conventional breeding methods, after years of system selection and breeding to cultivate a group of upland cotton with adaptability and appearance, quality indicators at or slightly higher than China The current production of long staple cotton land cotton-like cotton mutant line. In 1996, the selected plant materials and excellent lines were tested with HVI900 by the Provincial Cotton Research Center. In the selected lines, the average cashmere length was 3473 ± 139mm, which was 593mm higher than that of the control. The specific intensities were all over 24g / tex, with an average of 2675 ± 162g / tex, the highest reached 311g / tex, 605g / tex higher than the control, and the quality traits were coordinated with each other.
