甘蔗新品种在北海蔗区的种性表现和应用评价

摘要

9 new sugarcane varieties from the National Sugarcane Industry Technology System were included in the demonstration test in Beihai sugarcane area. The results showed that Guitang29, Funong38, Liucheng05-136 and Guitang31 performed well with economic characters better than that of the check. The top 3 varieties in cane yield were Guitang29, Funong38 and Liucheng05-136; the top 3 in sugar production were Guitang29, Funong38 and Guitang31; the variety with the highest sucrose content was Liucheng05-136. The economic trait of Guitang29 were significantly better than that of the check, and the overall performance of it in other traits were also good, showing great potential for popularization. Funong38, Liucheng05-136 and Guitang31 also showed certain promotion potential. The other participants, due to poor performance, might be difficult in the production application.%将国家甘蔗产业技术体系推出的9个甘蔗新品种在北海蔗区进行表征示范试验。结果表明，桂糖29号、福农38号、柳城05-136、桂糖31号等4个品种的表现较好，其经济性状均优于对照。蔗茎产量排前3位的品种是桂糖29号、福农38号、柳城05-136；蔗糖产量排前3位的是桂糖29号、福农38号和桂糖31号；蔗糖分含量最高的是柳城05-136。其中桂糖29号的经济性状明显优于对照，其他性状的综合表现也较好，具有较大的推广潜力，可以适度进行示范推广；而福农38号、柳城05-136、桂糖31号等品种，也具有一定的推广潜力，可以扩大试种；其他的参试品种因综合表现欠佳，可能难以在生产上应用推广。
