| Abstract: |
| Sugarcane parents containing Erianthus arundinaceus blood are very important to improve the drought
resistance of sugarcane. Taking ROC10 as，the line drought stress on 5 sugarcane parents（YCE03-106，YEC04-42，
YCE07-24，YCE07-56 and YCE07-71） with Hainan E. arundinaceus bloodline were tested at seedling stage and
longation stage. By the two methods of significant analysis and fuzzy comprehensive score from five aspects of plant
height injured rate，malondialdehyde（ MDA），plasma membrane permeability（ PMP），photosynthetic potential
（Fv/Fm） and actual photosynthetic quantum yield（ Y（Ⅱ）），the drought resistance evaluation was carried out. The
result showed that YCE03-106 was a high-class drought-tolerance parent. |
