16个糖能兼用甘蔗品种（系）种性比较

为了解不同糖能兼用甘蔗品种（系）的种性和生产性表现，为今后进行能源甘蔗品种选育和推广提供参考，以广西主栽甘蔗品种ROC22、ROC16作对照，对来自国内外的16个品种（系）在2种不同类型土壤蔗区进行2年新植1年宿根种性比较试验。结果表明 B1、B8、GT26、GT02/833、B9、B28、GT02/48、GT97/69、GT02/208等品种（系）在生物产量、蔗茎产量、蔗糖产量和总可发酵糖产量等方面明显超过对照种ROC22、ROC16，具有丰产性好、抗逆性强、适应性广的优良种性，可在广西的旱地和水田蔗区既可作糖料蔗，也可做能源蔗种植利用。YT96/86、GT99/156和FN94/0403综合表现一般，可在桂南的水田蔗区因地制宜种植。其余品种（系）表现较差，不宜在广西扩大种植和推广。

Comparison of characteristics among 16 sugar and energy cane varieties

The aim was to know the difference of production and characteristics traits in different varieties （clones）. The result was used to provide the reference for energy sugarcane selecting and extending. With the main cultivated sugarcane varieties‘ROC22’and‘ROC16’as control, 16 varieties were comparative test, two-plant and one-ratoon crop, tow type soil. The results showed that： the varieties‘B1’,‘B8’,‘GT26’, ‘GT02/833’,‘B9’,‘B28’,‘GT02/48’,‘GT97/69’,‘GT02/208’performed well in high cane yield, stress resistance and strong adaptability. And the biological yield, cane yield, sugar yield and total fermentable sugar yield of them were significantly higher than CK, could be planted as sugar and energy cane cultivars in Guangxi. With the ordinary characteristics traits, the varieties‘YT96/86’,‘GT99/156’and‘FN94/0403’ might be planted in paddy field of the south of Guangxi. And other varieties （clones） were not well to expand planting in Guangxi.
