Abstract:

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, ROC16 as control, 16 varieties were comparative test, two-plant and one-ratoon crop, tow type soil. The result 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 the other varieties (clones) were not well to expand planting in Guangxi.
