| Abstract: |
| Nineteen cotton cultivars (Gossypium hiristurum) suitable for Hexi area of Gansu were selected as test materials, and the comprehensive evaluation and classification at germination and seedling stages were performed by principal components analysis and hierarchical cluster analysis based on the salt tolerance coefficient of multi-indexes. The results showed that the salt tolerance of three cultivars (lines) at germination stage were not consistent with that at seedling stage among the nineteen cultivars (lines), accounting for 15.8% of the tested cultivars(lines), other cultivars (lines) showed salt tolerance at germination and seedling stages. Liao 195, Huiyuan 710, Jinkeng 108 were strong tolerant at both germination and seedling stages, Longzongmian 3, B10, Jinkeng 1261, Xinluzao 26, Xinluzao 33 were moderate tolarant, while Longmian 2, Xinluzao 10, Xinluzao 67, Longlumian 4, Jiumian 10, Xinluzao 39, Xinluzao 45 weak tolerant and Huamian 9 sensitive. |
