加速棉花品种资源的抗病性鉴定,是当前选择杂交亲本开展抗病育种的迫切需要,也是培育抗病、丰产、优质新品种的主要物质基础。我国现保存的品种资源约3,675份,其中陆地棉3,044个,海岛棉289个,亚洲棉316个,非洲棉14个,野生棉12个。大量的品种资源过去均未作过系统的抗病性鉴定,因为缺乏快速准确的测定方法,仅依靠田间病圃进行鉴定,所以进展缓慢,数量有限。我国在开展棉花枯萎病菌生理型研究时,

Accelerating the identification of disease resistance in cotton varieties is an urgent need to carry out disease-resistant breeding in the current selection of hybrid parents and a major material basis for cultivating new varieties with high disease resistance, high yield and good quality. There are about 3,675 varieties of resources currently being preserved in China, of which 3,044 are upland cotton, 289 are island cotton, 316 are cotton from Asia, 14 are from Africa and 12 are wild cotton. A large number of varieties of resources in the past have not made a systematic identification of disease resistance, because of the lack of rapid and accurate determination method, only rely on field nursery identification, so progress is slow, the limited number. When carrying out physiological studies on Fusarium oxysporum f.
