无毒棉是近20年来棉花家族中集粮(蛋白质)、棉(纤维)、油(棉油)、饲(枝、叶、茎、秆等)于一身的多用途作物。我国无毒棉发展迅速,目前已选育出具有丰产、优质,多抗的新品种10多个,种植地域跨及各棉区。随着种植面积的扩大和新品种的增多,无毒棉良种的繁殖体系亟待改进,现就无毒棉良种繁育特点及繁殖体系,进行一些探讨。一、无毒棉良种繁育特点无毒棉的茎、叶、花、铃、籽等器官内外均无色素腺(油点),任何部位发现有色素腺,均非所需的无毒棉。因此,它既具有 Non-toxic cotton is a multi-purpose crop in which the family of cotton (protein), cotton (fiber), oil (cotton oil), feeding (branches, leaves, stems, stalks, etc.) in the cotton family in the past 20 years. The rapid development of non-toxic cotton in China has now bred more than 10 new varieties with high yield, high quality and multi-resistance. With the expansion of planting area and the increase of new varieties, the breeding system of non-toxic cotton varieties needs to be improved urgently. Now, some characteristics of non-toxic cotton breeding and reproduction system are discussed. First, the non-toxic cotton seed breeding characteristics Non-toxic cotton stems, leaves, flowers, bell, seeds and other organs inside and outside the pigmented gland (oil point), any part of the pigmented gland are found, are not required non-toxic cotton. So it has both
