2010～2011年国家甘薯品种区试广西试点报告

Report on national sweet potato regional trial(Guangxi location)in 2010-2011

[目的]筛选适合广西种植的甘薯新品种（特别是高淀粉型新品种）,为提高广西甘薯良种覆盖率、推动甘薯产业结构调整提供品种支撑.[方法]2010～2011年在国家甘薯品种区试广西试点对9个甘薯新品种进行试验,测定甘薯鲜重、干重、品质等.[结果]9个参试品种中,鲜薯产量比对照增产的品种有3个,依次为泉薯10号、金薯2号和福薯21,其中泉薯10号产量名列第一（41006.3 kg/ha）,比对照增产60.4％;干薯产量比对照增产的品种有6个,依次是金薯2号、泉薯10号、桂粉3号、莆薯16号、广薯205、龙薯14,其中金薯2号产量最高（9797.8 kg/ha）,比对照增产45.3％.莆薯16号的干物率最高,为34.85％;桂粉3号的熟食味最好,评分为87.5分.[结论]高淀粉品种桂粉3号、广薯205、龙薯14及其他类型品种泉薯10号、金薯2号和福薯21等综合表现较好,适于在广西全区或部分地区种植.

[Objective]Newly-developed sweet potato varieties adapting to Guangxi, especially those with high-starch, were screened to provide references for promoting the coverage of improved sweet potato cultivars and advancing the restruc- turing of sweet potato industry in Guangxi. [ Method ]In 2010 and 2011, 9 newly-developed sweet potato varieties were evaluated in Guangxi using randomized complete block design. The data such as fresh and dry yield and quality were collect- ed and analyzed. [Result]Three out of the 9 tested varieties, namely Quanshu 10, Jinshu 2 and Fushu 21, produced higher fresh yield than the control. Among them, the fresh yield of Quanshu 10 ranked first （41006.3 kg/ha）, which was 60.4% higher than that of the control. Six out of the 9 tested varieties, namely Jinshu 2, Quanshu 10, Guifen 3, Pushu 16, Guangshu 205 and Longshu 14, had better performance than the control in dry yield. Among them, the dry yield of Jinshu 2 reached 9797.8 kg/ha and ranked first, which was 45.3% higher than that of the control. Pushu No.16 showed highest rate of dry matter, which was 34.85%. Guifen 3 expressed best flavor with the score of 87.5. [Conclusion]High starch varieties such as Guifen 3, Guangshu 205 and Longshu 14 and other varieties such as Quanshu 10, Jinshu 2 and Fushu 21 are suitable for planting across Guang＇xi or part of Guangxi.
