棉花是锦葵科棉属植物,共包括39个种,除了大面积栽培的陆地棉以及海岛棉、亚州棉(也称中棉)和非州棉(也称草棉)4个栽培种外,其余35个种都是野生的。经研究,棉属野生种中存在对于棉花育种非常需要而丰富的种质资源,例如抗病、虫,耐低温、盐碱,高纤维强力以及其他一些特殊的性状。将这些有益的性状转移到生产上推广的棉花品种中,具有十分重要的价值。一般是通过种间杂交的方法来达到此目的。但是棉属中大多数的种间杂交存在严重的不亲
Cotton is a Malvaceae cotton, a total of 39 species, in addition to large-scale cultivation of Upland and Sea Island cotton, Asian cotton (also known as cotton) and non-state cotton (also known as grass cotton) 4 cultivars The remaining 35 species are wild. According to the research, germplasm resources such as disease resistance, insects, low temperature tolerance, salinization, high fiber strength and some other special traits are very much needed in wild cotton species for cotton breeding. The transfer of these beneficial traits to cotton varieties that are widely promoted in production is of great value. This is usually done through interspecific hybridization. However, most interspecific hybrids in Gossypium have serious non-relatives
