广西紫色甘薯品种比较试验

选用广西玉米研究所选育的8个紫色甘薯新品种，以宁紫薯1号为对照，在广西设8个点进行紫色甘薯品种比较试验。结果表明，桂07—160的平均鲜薯、干薯产量最高，熟食味优，适应性广，综合表现最优，可在广西大面积推广；桂06—123平均鲜薯产量居第2位，食味中等，适应性也较好，可在广西大面积推广；桂07—157平均鲜薯产量居第3位，干物率最高，达37．1％，适宜作为能源型甘薯在生产上应用；桂06—280、桂05—180和桂05—188综合表现中等，适合在广西不同地区种植；桂薯12和桂04—96综合表现较差，不宜在广西推广种植。

A comparative study on purple sweet potato varieties in Guangxi

In the present study, eight new purple sweet potatoes bred by Guangxi Maize Research Institute were selected for comparative experiments in eight locations in Guangxi,Ningzishu 1 was used as the control. The results showed that the performance of Gui 07-160 was better than other varieties for yield (fresh weight and dry weigh), better taste, wide adaptability, etc., and it could be extended for large scale production in Guangxi. The average yield (fresh weight) of Gui 06-123 was the second with good taste a...
