在四川米易进行的3年4点(次)全国第三轮区试新植、宿根试验结果表明,川糖89-103综合性状表现突出,甘蔗单产和含糖量居首位;闽糖86-2121、粤农91—854、福农91—4710和闽糖93-246及川宁85-78的大多数工农艺性状优良,甘蔗单产和含糖量都较高。前述品种(系)可在四川攀西蔗区扩大种植。粤糖93-159、桂糖93-103、云蔗92-19等的部分性状表现优良,可在条件适宜的地块种植。桂糖92-262、粤糖92-126、粤蔗C25、云蔗89-351、粤糖92-373和福农93-3608等品种(系)的多数性状表现不突出,有待继续试验观察。

Four comparison experiments were carried out on plant and ratoon of new sugarcane varieties in the national third round regional test in Miyi County of Sichuan Province. The results indicated that the comprehensive character of CT89-103 was every outstanding, and its sugarcane yield and cane sugar yield was stood at the first place among the varieties. Most characters, both agronomic and technical, of MT86-2121, YN91-854, FN91-4710. MT93-246 and CN85-78 were excellent and per unit area yield of sugarcane and sugar were higher, suitable for propagation in Panxi region. Some characters of MT93-159, GT93-103, YZ92-19 etc. were fine, and can be planted in the areas of suitable conditions. Most characters of MT92-262, YT92-126, YZC25, YZ89-351, YT92-373 and FN93-3608 etc. seemed poor and should be experimented for more observation.
