| 摘 要： | 为了解甘蔗新品系桂糖03-2287的农艺性状等表现,对2011/2012和2012/2013年度广西甘蔗品种区域试验点桂糖03-2287和对照新台糖22号(ROC22)两年新植和一年宿根的试验获得的相关数据进行综合分析。桂糖03-2287第一年新植、第二年新植和第一年宿根的出芽率均高于对照;分蘖率较对照低;甘蔗前期生长较ROC22快,后期株高与对照接近;各个试验点新植宿根的平均茎径均比ROC22大;平均有效茎数多于或者接近对照ROC22。桂糖03-2287新植、宿根以及新植宿根平均的理论产量均高于ROC22,分别增12.6%~14.6%、3.0%和8.7%,且最高理论产量达146.93 t/hm2。桂糖03-2287在新植和宿根中,较对照ROC22表现出植株高大、中大茎、有效茎数多、产量高等优点,可在广西甘蔗生产上因地制宜地推广应用。

| Abstract: | The study was conducted to evaluate the performance of agronomic characters for a new sugarcane clone GT 03-2287. The data including two plant crops and one ratoon crop, from Guangxi sugarcane regional trial during the years of 2011/2012 and 2012/2013, GT 03-2287 and ROC22 were compared. The average of germination rate in GT 03-2287 was higher than ROC22, in the two planting crop and one ratoon crop, and the average of tillering rate was lower than CK. GT 03-2287 grew faster than ROC22 in the early stage, and the plant height was similar with ROC22. The average of stalk diameter was larger than of CK. And the averages of millable stalk were more than ROC22 or similar with CK. The averages of theoretical yield in planting crops and ratoon crop of GT 03-2287 were higher than in ROC22, and the yields were increased 12.6%~14.6% or 3% and 8.7%, respectively. The highest theoretical yield was attained with 146.93 t/ha. For both plant and ratoon crops, GT 03-2287 showed higher plant, middle or large stalk diameter, more millable stalk and higher yield than in ROC22. Therefore, GT 03-2287 could be as an excellent commercial variety for sugarcane production in Guangxi. |
