粤北霜冻蔗区甘蔗新品种比较试验

Sugarcane Variety Trials in the Frosted Region in North Guangdong

在粤北翁源蔗区对18个甘蔗新品种进行了2年新植1年宿根试验,结果表明:新植宿根平均蔗产量居前4位的品种有引1号、引9号、闽糖86-05和粤糖93-159,平均蔗茎产量均较对照种R0C10增产20％以上;新植宿根单位面积平均含糖量居前五位的品种有引9号、引1号、粤糖93-159、R0C25和R0C22,均较对照种新台糖10号增产糖15％以上;新植宿根平均蔗糖分(11月至次年1月)居前5位的品种有引9号、引8号、引1号、粤糖93-159和引6号,平均蔗糖分均超过14.3％,其中引9号平均蔗糖分达15.63％,11月上旬蔗糖分超过15％,成熟高峰期达17％。综合性状表现较优良的品种有引9号、粤糖93-159,这两品种均表现特早熟高糖、高产、分蘖性强、粗生易种。

The results from two years' experiments on the 18 sugarcane varieties in Yongyuan sugarcane region, including two plant cane and one ratoon cane, showed that the cane yield of Yin 1, Yin 9, MT86-05 and YT93-159 were at least 20 % higher than that of the check variety ROC 10, and the sugar yield of Yin9, Yin 1, YT93-159. ROC25 and ROC22 were more than 15 % higher than that of ROC 10. The mean sucrose content in cane (absolute value) of Yin9, Yin8, Yinl, YT93-159 and Yin6 were above 14.30% from Nov. through Jan., and ranked first to fifth, respectively. The average sucrose content of Yin9 was 15.63%, up to 15% in Nov., and maximizing 17%, respectively. Yin9 and YT93-159 were promising varieties of very early maturity, high cane and sugar yields, strong tillering ability, as well as easy stripping.
