Abstract: Sp71-6180 was a sugarcane variety, which was newly introduced from Mexico in 1995 and bred by Yunnan sugarcane research institute via epidemic test, propagation, screening and regional trial in Yunnan. It is characterized with strong germination, good vigor, good ratooning, medium-small stem, early maturing, high sucrose and yield. The trail results show that the mean yield is 100.95t/hm², and increases by 24.1% and 16.6% higher than that of check variety GT11 and ROC10 respectively, the mean sucrose content is 14.89%, increases by 0.58% and 0.59% higher than that of check variety respectively and the sucrose content reaches 13.27% in the November(indicated early maturing), the mean sugar yield is 15.6t/hm², increases by 30.1% and 25.4% higher than that of check variety respectively. Sp71-6180 has the broad adaptation ability, is resistant to smut and drought and was examined and approved by Yunnan crop variety administration committee in October, 2004.
