2013～2014年甘蔗品种区试试验结果及分析——以广西百色试点为例

The results and analysis for regional trial of sugarcane varieties in 2013～2014——Case study of Baise pilot area in Guangxi

【目的】对各参试品种在百色生态区的表现进行评价与分析,为广西甘蔗品种结构调整、甘蔗品种更新换代以及品种的审定和开发利用提供重要依据。【方法】进行2年新植1年宿根12品种试验,采用完全随机区组排列,3个重复一次性施肥,覆盖除草地膜。田间各项管理按当地大田栽培管理措施进行。【结果】综合农艺性状及蔗茎产量、甘蔗糖分和含糖量等经济性状,表现较好的品种依次为"桂糖06-3283"、"桂糖06-244"、"桂糖06-1721"等3个品种。其中"桂糖06-3283"产量为124.94t/hm2,比对照减产1.07个百分点,排名第四,其糖分为15.02%,排名第一,比对照高0.6个百分点,含糖量达18.72t/hm2,比对照增产0.57%,排名第一;"桂糖06-244"产量为129.85t/hm2,比对照增产3.84个百分点,排名第一,其糖分为14.38%,排名第七,比对照第0.04个百分点,含糖量达18.66t/hm2,比对照高0.51个百分点,排名第二;"桂糖06-1721"产量为122.54t/hm2,比对照减产3.47个百分点,排名六,其糖分为14.91%,比对照高0.49个百分点,排名第二,含糖量达18.27t/hm2,比对照高0.12个百分点,排名第三。【结论】各参试品种(系)表现差异不显著,综合农艺性状、工艺性状,表现较好的是"桂糖06-3283"、"桂糖06-244"、"桂糖06-1721"等3个新品系。

【Objective】Evaluation and analysis of the performance of various testing varieties in Baise ecoregion, in order to provide the reference for structure adjustment, varieties replacement, authorized varieties,and development and utilization of examination sugarcane in Guangxi.【Method】Conducted sugarcane variety trial, which including 12 varieties, applying the arrange of randomized block with 3 repetition of one- off fertilization, covering weeding film.The management of the field is according to local field cultivation management measures. 【Results】The results show that, comparing the follows comprehensive economic properties：agronomic traits, cane yield, sugar content and sugar degree, the highly valued order of sugarcane varieties are as follows： Guitang 06- 3283, Guitang 06- 244, Guitang 06- 1721,etc.【Conclusion】There are no significant difference among each testing varieties, comparing the agronomic traits and process properties, the good performance in order are the three newly- strains：Guitang 06- 3283, Guitang 06- 244, Guitang 06- 1721.
