全国甘蔗新品种比较

Comparison of New Varieties of Sugarcane in China

[目的]为甘蔗新品种的推广提供参考依据。[方法]以Roc22号为对照,对国家甘蔗产业技术体系提供的9个甘蔗品种进行比较,筛选综合性状表现较好的甘蔗品种。[结果]甘蔗品种粤糖55、福农15、桂糖02-901、粤糖00-236萌芽率较高;粤糖55、粤糖00-236分蘖率高。蔗茎产量高于对照的有粤糖55、桂糖97-69、粤糖00-236和福农15几个品种,蔗糖分较高的为桂糖02-901和云蔗99-91。云蔗99-91、云蔗03-422、粤糖55、甘蔗品种粤糖00-236几个品种耐寒性较强。公顷含糖量较高的为粤糖55、福农15、粤糖00-236和桂糖97-69。[结论]甘蔗品种粤糖00-236和福农15号综合性状表现较好,可繁殖推广。

[ Objective ] The aim was to provide basis for the popularity of new varieties. [ Method ] 9 varieties of cane provided by national cane industrial technology system were studied. [ Result] YT55, Funong15, GT02-901, YT00-236 and so on had higher germination rates. YT55 ,YT00-236 had higher points rates. The varieties whose cane productions were higher than reference were YT55 ,GT97-69,YTO0-236 and Funongl5. The varieties whose sugar was higher were GT02-901 and YZ99-21 while YZ99-91 ,YZ03-422 ,YT55 ,YT00-236 had stronger cold resistance. But YT55,Funong15,YTO0-236 and GT97-69 produced more sugar per hectare. [ Conclusion] YT00-236 and Funong15 had better integrated traits. Thus, they can be cultivated and promoted.
