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。
In order to understand the species and productive performance of sugarcane varieties (lines) with different sugar and sugar content, and to provide references for breeding and popularizing energy sugarcane varieties in the future, the main sugar cane varieties ROC22 and ROC16 in Guangxi were compared. A variety of (lines) in two different types of soil sugarcane area 2 year new planted 1 year of perennial species comparison test. The results showed that the biomass, cane yield, sucrose yield and total fermentable sugar yield of B1, B8, GT26, GT02 / 833, B9, B28, GT02 / 48, GT97 / 69 and GT02 / Which obviously surpassed that of the control ROC22 and ROC16. It has the characteristics of high yield, strong resistance and wide adaptability. It can be used as sugar cane and energy cane planting in dry and paddy fields in Guangxi. The general performance of YT96 / 86, GT99 / 156 and FN94 / 0403 can be planted in the sugarcane field of paddy field in Guinan. The remaining varieties (lines) performed poorly and should not be expanded in Guangxi to plant and promote.
