棉籽仁含有丰富的蛋白质、油脂和维生素,是一种重要的新型营养源。一般棉花品种含有1.6～2.8%的棉酚(棉毒素),能使人体和单胃动物中毒,所以不能食用,限制了棉籽的开发利用。近半个世纪以来,世界各国积极开展了低酚棉品种的选育工作,并取得了很大进展。50年代初,美国在普通棉中发现了低酚棉突变体,后来又在印第安自然保护区发现了无酚野生棉,经过精心研究,杂交培育和多代选择,育成了低酚棉 CG102、CG104等新品种,其棉籽仁含油脂和蛋白质都为
Cottonseed is rich in protein, fat and vitamins, is an important new source of nutrition. General cotton varieties contain 1.6 to 2.8% of gossypol (cotton toxins), can make the human body and monogastric animals poisoning, it can not eat, limiting the development and utilization of cottonseed. Nearly half a century, all countries in the world actively carry out breeding of low-phenolic cotton varieties, and made great progress. In the early 1950s, the United States discovered low-phenol cotton mutants in common cotton and later found no-phenol wild cotton in the Indian Nature Reserve. After careful study, cross breeding and multi-generation selection, low-phenol cotton CG102 and CG104 And other new varieties, their cottonseed oil and protein are
