| 摘 要： | 1988-1991年进行的棉花抗硃砂叶螨试验表明,海岛棉和二倍体栽培棉(中棉和草棉)对硃砂叶螨具有较高水平的抗性,它们的抗螨性已通过远缘杂交技术转移到了感螨的陆地棉栽培品种中。来自四川省和河南省的一些品种以及来自美国的PD种质系对硃砂叶螨的抗性比湖北省当地品种要差。叶片有毛,无腺体和高含淀粉的棉花,硃砂叶螨为害较重;而叶片具有致密茸毛、棉酚、可溶性糖、叶绿素和类黄酮含量高以及叶片鲜重高的品种抗螨性较强。

| Abstract: | A series of experiments concerned with the resistance of cotton varieties to carmine spider mite (CSM) Tetranychus cinnabarinus Boisduval were conducted in Wuhan in 1988-1991. The results showed that the island cotton Gossypium barbadense and cultivated diploid cotton G. arboreum and G. herbaceum possessed rather high resistance to CSM. Their resistance had been transferred into the susceptible upland cotton G. hirsutum by using a distant hybridization technique. The upland cotton varieties from Sichuan and Henan Provinces and the PD germplasm lines from USA were more susceptable than the local varieties grown in Hubei Province. Cotton with pubescence and high starch content and without gland in leaves were severely damaged by CSM. Whilst, those with dense leaf trichomes, high gossypol, soluble sugar, chlorophyll and flavonoid contents, and high fresh leaf weight tended to have less CSM infestation. |
