Comprehensive evaluation on new self-cultivated sugarcane lines by grey relational analysis

Thirteen main agronomic characters of 10 sugarcane lines were evaluated by Grey Relational Analysis. The result showed that the grey correlation degree of self-cultivated lines GNY08-212 0.7497 GNY08-1860.7227 GNY08-3200.7206 GNY08-336 0.7005 GNY08-3530.6928 were higher than ROC22 (CK), so the 5 lines could be further tested, and the others were worse than CK, should be further observed or eliminated.
