摘 要：
【目的】综合评价13个参试甘蔗品种的丰产性、适应性和稳产性,为广西甘蔗新品种的审定和推广提供科学依据。【方法】以广西当前主栽品种ROC22为对照,于2012~2013年在南宁、柳州、河池、百色、北海、崇左6个试验点进行两年新植1年宿根甘蔗新品种比较试验和生产试验,对其丰产性、适应性和稳产性等进行综合评价。【结果】13个参试品种中,桂糖04-1045、桂糖05-1141、桂糖04-1545和柳糖07-95表现早熟、高糖、高产稳产,蔗茎产量分别比对照增产1.08%、4.53%、5.49%和9.45%,蔗糖分分别比对照提高0.517%、0.572%、0.784%和0.882%(绝对值),产糖量分别比对照增加4.38%、8.51%、11.50%和16.09%;桂糖03-66和桂糖03-91蔗茎产量分别比对照减产14.53%和9.85%,蔗糖分分别比对照提高1.326%和0.829%(绝对值),表现特早熟高糖,但产量较差;桂糖03-591和桂糖06-533蔗茎产量分别比对照增产12.65%和9.98%,蔗糖分分别比对照降低0.398%和0.627%(绝对值),表现中熟高产,但糖分偏低;其他品种产量及蔗糖分表现均稍差。参试品种在各试验点表现不同,桂糖04-1545在南宁点表现较好,柳糖07-95、桂糖04-1045和桂糖04-1545在柳州点表现较好,桂糖05-1141、柳糖07-95、桂糖04-1545和桂糖04-1045在河池点表现较好,百色点没有表现增产且增糖的品种。【结论】桂糖04-1545、柳糖07-95、桂糖05-1141和桂糖04-1045在试验中综合表现较好,达到广西甘蔗品种审定的标准,建议因地制宜加以推广。

摘 要：
【Objective 】The high yield performance, adaptability and yield stability of 13 sugarcane varieties were comprehensively evaluated in order to provide scientific basis for the approval and registration, and extension of new sugarcane varieties in Guangxi. 【 Method 】 Taking ROC22 as the control, the comparative test and production test of two-year new planting and one-year ratoon for 13 new sugarcane varieties were conducted at 6 locations viz.,Nanning, Liuzhou, Hechi, Baise, Beihai and Chongzuo in Guangxi during 2012-2013. The high yield performance,adaptability and yield stability were evaluated by using Tai or AMMI model, and so on. 【Result 】Amongst the 13 tested sugarcane varieties, GT04-1045, GT05-1141, GT04-1545 and LT07-95 showed early maturity, high sucrose,high and stable yield. Their cane yield were increased by 1.08%, 4.53%, 5.49% and 9.45% compared with ROC22,the sucrose were increased by 0.517%, 0.572%, 0.784% and 0.882%(absolute value), and the sugar yield were increased by 4.38%, 8.51%, 11.50% and 16.09% compared with ROC22, respectively. GT03-66 and GT03-91 showed special early maturing, high sucrose and poor yield. Although their sucrose were increased by 1.326 % and0.829%(absolute value), the cane yields were decreased by 25.78% and 9.85% compared with ROC22, respectively.GT03-591 and GT06-533 were charactered by middle maturity, high yield and low sucrose, the cane yield increased by 12.65% and 9.98%, while the sucrose decreased by 0.398% and 0.627%(absolute value)compared with ROC22,respectively. According to the comprehensive performance of yield and sucrose, GT04-1545 had good performance in Nanning city, LT07-95, GT04-1045 and GT04-1545 had better performance in Liuzhou city, and GT05-1141,LT07-95, GT04-1545 and GT04-1045 presented good performance in Hechi city, but no varieties showed good performance both of cane yield and sucrose in Baise city. 【Conclusion 】GT05-1545, LT07-95, GT05-1141 and GT04-1045 showed good performance and reached the registration standard of Guangxi sugarcane variety, which could be recommended for extending in Guangxi.
