【摘要】 我国自１９７３年开始研究低酚棉，已培育出豫棉２号、６号，中棉１３号、１８号，湘棉１１号、１３号，浙棉９号，皖棉５号，辽棉１１号，新陆早１号、３号，新陆中２号等十几个低酚棉品种。这些品种棉仁游离棉酚含量均低于国际卫生标准（０．０２％～０．０４％），皮棉产量相当于当地有酚棉品种，纤维品质符合国家优质棉指标，并且多数品种高抗枯萎、耐黄萎，棉仁蛋白质含量４０％左右，脂肪含量３５％左右。研究还认为，棉蚜、棉红蜘蛛对低酚棉的危害比有酚棉轻，棉铃虫、地老虎、造桥虫等对低酚棉和有酚棉的危害无明显差异，棉盲椿蟓、棉蓟马对低酚棉的危害比有酚棉重。１９９３年全国种植低酚棉１０万多公顷。各地对低酚棉副产品的饲料、食品、医药等用途进行了研究，同时还开展了有关低酚棉的基础研究，并获有益进展。更多还原

【Abstract】 The studies on glandless cotton in China were begun in 1973. UP to now,12 glandless varieties such as Yumian 2,6,Zhongmian 13,18,Xiangmian 11,13,Zhemian 9,Wanmian 5,Liaomian 11,Xinluzao 1,3 and Xinluzhong 2 have been released.The lint yields of these glandless varieties were equivalent to those of present glanded varieties,the fibers were up to the standard of high-quality cotton,the qossypol contents in seed kernel were lower than the international sanitation standard(0.02%～0.04%)and the protein and oil contents in seed kernel were respectively about 40% and 35%.Studies show that aphids and red spides were easier to damage glanded than glandless varieties,bugs and thrips were easier to damage glandless than glanded varieties and bollworms damage glanded and glandless varieties with no difference.The total glandless cotton growing area in China is over 100000 hm2 in 1993.The uses of glandless cotton as forage,food and medicine are also studied in China and some progresses have been made.更多还原
