【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。
【Objective】 The objective of this study was to evaluate the high yield, adaptability and stability of 13 varieties of sugarcane cultivars and provide a scientific basis for the validation and promotion of new varieties of sugarcane in Guangxi. 【Method】 With the current cultivated variety ROC22 in Guangxi as a control, two years of newly planted perennial sugar cane varieties were tested and produced in six pilot sites in Nanning, Liuzhou, Hechi, Baise, Beihai and Chongzuo from 2012 to 2013 Test, its high yield, adaptability and stability of a comprehensive evaluation. 【Result】 Among the 13 tested varieties, Guitang 04-1045, Guitang 05-1141, Guitang 04-1545 and Liuguan 07-95 showed early maturity, high sugar, high and stable yield, and cane yield increased by 1.08 , 4.53%, 5.49% and 9.45% respectively. The sucrose content increased by 0.517%, 0.572%, 0.784% and 0.882% (absolute value) respectively, and the sugar yield increased by 4.38%, 8.51%, 11.50% and 16.09 %; Cane sugar 03-66 and cane sugar 03-91 cane yields 14.53% and 9.85%, respectively, compared with the control, sucrose were increased by 1.326% and 0.829% (absolute value) than the control, showing particularly precocious high sugar, but the yield The yield of cane stem of Gui Zhi 03-591 and Gui Zhuan 06-533 increased by 12.65% and 9.98%, respectively. The sucrose content decreased by 0.398% and 0.627% (absolute value) Low; other varieties yield and sucrose performance were slightly worse. The test varieties showed different performance at each test point. Gui sugar 04-1545 performed better at Nanning, with Liuyou 07-95, Gui sugar 04-1045 and Gui sugar 04-1545 performed better at Liuzhou, Gui sugar 05- 1141, Liu sugar 07-95, Gui sugar 04-1545 and Gui sugar 04-1045 performed better in Hechi, Baise point no yield increase and sugar varieties. 【Conclusion】 Guitang 04-1545, Yanghua 07-95, Guitang 05-1141 and Guitang 04-1045 performed well in the experiment and reached the standard of validation of Guangxi sugarcane varieties. It is suggested that it should be popularized according to local conditions.
