几个甘蔗新品种比较试验初报

Preliminary report of comparison experiments on several new sugarcane varieties

以新台糖22号为对照品种,以园林17号、园林18号、桂糖02/467、桂糖02/901、柳城03/182、新台糖88/99等6个甘蔗新品种为材料进行比较试验。试验结果表明,与对照新台糖22号相比,桂糖02/467与柳城03/182出苗率较高,其分蘖率相对较低;出苗率较低的品种如园林17号、桂糖02/901,其分蘖率相对较高。在生长盛期,柳城03/182表现出良好的农艺性状,其伸长生长最快,田间锤度较高;桂糖02/467与新台糖88/99表现出中大茎;柳城03/182与桂糖02/901表现出早熟高糖;但参试的几个甘蔗品种实际产量均低于对照新台糖22号。

Sugarcane variety ROC22 was used as the control; six new sugarcane varieties for example YL17,YL18, GT02/467, GT02/901, LC03/182, ROC88/99 were used as varieties for comparative experiment. The results showed that the varieties GT02/467 and LC03/182 showed stronger emergence rate and lower tillering rate than the eontrol variety ROC22. Then the varieties YL17 and GT02/901 were on contrary. The variety LC03/182 grew fast at the elongate stage with high field brix, and the varieties GT02/467 and ROC88/99 showed mid-large stalk. It was higher of field brix for the varieties LC03/182 and GT02/901.The varieties LC03/182 and GT02/901 matured earlier and contained higher sugar content than other varieties. But in the yield, all the new sugarcane varieties were lower than the control variety ROC22.
