Abstract
The grey relational analysis (GRA) was used to evaluate the 10 sugarcane lines by 13 main agronomic characters. The result showed that the grey correlation degree of self-cultivated lines GNY08-320 (0.7502), GNY08-336 (0.7409), GNY08-186 (0.7369), and GNY08-225 (0.7277) were higher than ROC22 (CK), so the 4 lines can be further tested, and the others were worse than CK that should be further observed or eliminated.
