测定了23个云蔗优良品种在四川蔗区自然低温寒害条件下的抗寒性(对照种为ROC22)。结果表明,云蔗03-194、云蔗05-51、云蔗05-49、云蔗07-2007、云蔗08-1095、云蔗08-1609、云蔗05-326和云蔗07-2178八个品种(系)高产高糖,抗寒性好;云蔗06-193、云蔗04-622、云蔗03-258、云蔗06-407、云蔗05-211、云蔗05-39和云蔗08-1145七个品种(系)农艺性状和抗寒性总体优于对照,其它参试品种不及ROC22。
The cold resistance of 23 excellent sugarcane varieties in natural low temperature and cold damage in Sichuan sugarcane (ROC22) was measured. The results showed that Yunzha 03-194, Yunzhan 05-51, Yunzhan 05-49, Yunzhan 07-2007, Yunzhan 08-1095, Yunzhan 08-1609, Yunzhan 05-326 and Yunzhan 07-2178 Eight varieties (lines) high yield and high sugar, good cold resistance; cloud cane 06-193, cloud cane 04-622, cloud cane 03-258, cloud cane 06-407, cloud cane 05-211, cloud cane 05-39 And Yunxian 08-1145, the agronomic traits and cold resistance of seven cultivars (lines) were better than those of the control. The other cultivars were not as good as ROC22.
