广西甘蔗品种比较试验

目的]综合评价甘蔗新品种的丰产性、稳定性和适应性,筛选出适合广西蔗区种植的甘蔗新品种。方法]以广西主栽甘蔗品种新台糖22号(CK_1)和新台糖16号(CK_2)为对照,于2009—2010年对10个参试甘蔗品种在南宁、柳州、河池、百色、贺州、来宾、龙州和合浦8个区试点进行2年新植1年宿根甘蔗新材料的比较试验,对其综合性状进行评价。结果]10个参试品种中,桂糖02-281和桂糖03-2357的蔗茎产量表现突出,分别比对照CK_1增产18.76%和7.46%,比对照CK_2增产26.17%和14.16%;蔗糖分表现最佳的为桂糖03-1403,分别比CK_1和CK_2高1.15%和1.10%;桂糖02-281、桂糖03-2357、桂糖03-1403、桂糖02-1156的含糖量均比对照高5.00%以上。参试材料中,柳城04-12的产量分别比CK_1和CK_2减产10.85%和5.29%,含糖量分别比CK_1和CK_2减少10.70%和3.10%,表现较差。结论]桂糖02-281在2009—2010年区域试验中综合表现最优,具有高产、稳产、宿根性好、有效茎数多等特性,适宜在广西不同蔗区推广种植。

Comparision Trial of Guangxi Sugarcane Varieties

Objective]The high yield performance,adaptability and yield stability of sugarcane varieties were comprehensively evaluated in order to select the new sugarcane varieties for plant in different ecological climate zone in Guangxi.Method]ROC22 (CK1) and ROC16 (CK2) were the controls which were the main planting sugarcane varieties in Guangxi.The comparative test of two plant crops and one root crop for 10 new sugarcane varieties were conducted at Nanning,Liuzhou,Hechi,Baise,Hezhou,Laibin,Longzhou and Hepu in Guangxi during 2009-2010.Result] The cane yield of GT02-281 and GT03-2357 were the standouts performance in the 10 clones,respectively,which were 18.76% and 7.46% higher than CK1,which were 26.17% and 14.16% higher than CK2.The highest sucrose content was GT03-1403 which was 1.15% and 1.10% than CK1 and CK2.The sugar yield of GT02-281,GT03-2357,GT03-1403 and GT02-1156 were higher than 5.00%.In all of 10 varieties,LC04-12 was the poor performance,respectively,which was 10.85% and 5.29% lower than CK1 and CK2,and the sugar yield which was 10.70% and 3.10% lower than CK1 and CK2.Conclusion] GT02-281 show the good performance with high yield,stability yield,good ratoon ability and more millable stalks in regional trial of Guangxi sugarcane varieties during 2009-2010,and which can be recommended for sugarcane production in Guangxi.
