| 摘 要： | Sp71-6180是云南省农科院甘蔗研究所1995年从墨西哥引进,经过引种疫情检测、繁殖观察、试验筛选和全省甘蔗品种区试及生产示范选择而成的优良甘蔗新品种。Sp71-6180出苗整齐,生势强,脱叶性好,成茎率高,宿根性强,为中小茎种,早熟高糖高产种。该品种通过各试验阶段表明:平均产蔗100.95t/hm2,比对照ROC10增产24.1%,比桂糖11号增产16.6%;甘蔗平均含糖分14.89%,比对照ROC10高0.58%,比桂糖11号高0.59%,其中,11月份甘蔗含糖分13.27%,较二对照高1.36%～1.63%;平均含糖15.6t/hm2,比对照ROC10增产30.1%,比桂糖11号增产25.4%。该品种适宜于旱地栽种,适应性广,经过黑穗病人工接种鉴定为1级高抗。该品种表现优良,达到国家甘蔗新品种审定标准,于2004年10月通过云南省作物品种审定委员会审定。

| 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 JP2](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. |
