2008~2009年广西甘蔗品种区域试验报告

目的]了解甘蔗新品种的丰产性及适应性,筛选出适合广西蔗区种植的甘蔗新品种.方法]以ROC22和ROC16为对照,2008~2009年在南宁、柳州、河池、百色、贺州、来宾、崇左和合浦等区试点进行两年新植1年宿根甘蔗品种比较试验和生产试验,对10个参试甘蔗新品种进行丰产性和适应性鉴定.结果]10个参试品种中桂糖02/208早熟高糖高产稳产,是综合表现最好的品种;柳城03/1 82和桂糖02/901表现特早熟特高糖稳产;桂糖02/770、桂糖02/833表现中晚熟高产中糖;桂糖02/1247和柳城03/1137表现晚熟高产中糖.结论]桂糖02/208、柳城03/182、桂糖02/901、桂糖02/770、桂糖02/833、桂糖02/1247和柳城03/1137达到广西甘蔗品种审定的标准,可因地制宜加以推广.

Preliminary report on regional trial for sugarcane varieties in 2008-2009 in Guangxi

Objective]The aim of this experiment was to assess the yield performance and adaptability of new sugarcane varieties and select appropriate ones for planting in Guangxi.Method]Comparative production trials of two planting cane and one-year-old ratoon were conducted using 10 new sugarcane varieties and 2 control varieties(ROC22 and ROC16) during 2008-2009 at 8 locations,viz.,Nanning,Liuzhou,Hechi,Baise,Hezhou,Laibin,Chongzuo and Hepu in Guangxi to evaluate the yield performance and adaptability of 10 new sugarcane varieties.Result]Amongst the tested varieties,the variety GT 02/208 showed best comprehensive traits with early maturity,high and stable yield of cane and high sugar yield.The varieties LC 03/182 and GT 02/901 were particularly early maturing with high sugar yield and steady cane yield.The varieties GT 02/770 and GT 02/833 were mid-late maturing with high cane yield and medium sugar yield.The varieties GT 02/1247 and LC 03/1137 were late maturing with high cane yield and medium sugar yield.Conclusion]The varieties GT 02/208,LC 03/182,GT 02/901,GT 02/770,GT 02/833,GT 02/1247 and LC 03/1137 were suitable to be extended for planting in Guangxi.
