研究棉属的分类与进化,对于棉花的育种工作(特别是远缘杂交)十分重要。近年由于抗病虫育种的需要,一些国家已重视利用野生棉种作为培育特强抗性的一种途径;如通过栽培棉种与野生棉种的杂交而得到抗病(尤其是抗枯、黄萎病)的品种。实践证明这是一种很有成效的方法。 Studying the classification and evolution of Gossypium is very important for cotton breeding (especially distant hybridization). In recent years, due to the need of resistance to disease and insect breeding, some countries have paid great attention to the use of wild cotton as a way to cultivate super-strong resistance; such as resistance to disease through hybridization of cultivated and wild cotton species Wilt disease) varieties. Practice has proved that this is a very effective method.
