2002～2004年广西甘蔗新品种区试表现

Experimental Report of Guangxi Sugarcane Varieties Regional Test

2002～2004年在广西5个试点进行2年新植、2年宿根甘蔗新品种区域试验,4年20次P44蔗茎产量最高,平均每公顷产蔗量为99041kg,其次是Q141为97553kg,Mex105为92299kg,新台糖25号为86415kg,台优为86141kg,比对照种新台糖16号分别增产20.30%、18.49%、12.11%、4.96%、4.63%;My55-14为81780kg、粤糖93/159为78285kg,比对照种减产0.67%和4.91%。4年60次(每年11月至次年1月3次)蔗糖分分析结果,粤糖93/159蔗糖分最高,平均达16.13%,Mex105为16.09%,Q141为15.49%,新台糖25号为15.12%,P44为15.07%,台优为15.01%,比对照种分别提高1.19%、1.15%、0.56%、0.19%、0.13%、0.07%,My55-14为13.82%,比对照种下降1.11%(绝对值)。

The Guangxi sugarcane varieties regional test was conducted in five sites from 2002 to 2004 （two year new plants and two year ratoons）. The experimental results showed that the mean cane yield of P44, Q141, Mex105, ROC25 and Taiyou was higher among 8 sugarcane varieties. The yield was 99041, 97553, 92299, 86415, 86141 kg/ha, which increased by 20.30%, 18.49%, 12.11%, 4.96%, 4.63%, in comparison with ROC16, respectively. The mean cane yield of My55-14 was 81780 kg/ha, Yuetang93/159 was 78285 kg/ha, which decreased by 0.67% and 4.91%, respectively. Cane sugar content of Yuetang93/159 was the highest between the varieties, it reached 16.13%, Mex105 was 16.09%, Q141 was 15.49%, ROC25 was 15.12%, P44 got 15.07% and Taiyou was 15.02%, which increased by 1.19%, 1.15%, 0.56%, 0.19%, 0.13%, 0.07%, respectively. Cane sugar content of My55-14 was 13.80%, which decreased by 1.11%.
