摘要： 为筛选适宜龙岩市种植的紫色甘薯新品种，采取一年多点完全随机区组试验设计，以“金山57”为对照，2014年夏季引进6个紫色甘薯新品种进行品种比较试验，从农艺性状、经济性状、鲜产、干产、淀粉产量、品质和花青素含量等方面进行筛选鉴定。结果表明：6个紫色甘薯新品种中，2个品种表现较好。其中，‘龙津薯1号’鲜薯产量最高，为39.11t/hm2，薯干产量9.22 t/hm2，淀粉产量5.53 t/hm2，干物率23.57%，淀粉率14.15%，食味评分80.0分，花青素含量17.66mg/100g。‘福薯24号’鲜薯产量其次，为36.30 t/hm2，薯干产量10.82 t/hm2，比对照增产3.32%，淀粉产量7.11 t/hm2，比对照增产6.77%。干物率29.81%，淀粉率19.57%，食味评分84.7分，花青素含量11.95mg/100g。‘龙津薯1号’鲜薯产量高，干物率和花青素含量指标适宜，可以推荐作为紫色地瓜干加工品种在龙岩市推广种植。‘福薯24号’鲜薯产量较高，食味品质好，干物率和淀粉产量高，可以推荐作为鲜食型和紫色淀粉加工型品种在龙岩市推广。‘广紫薯8号’将进一步观测。‘福宁紫3号’、‘宁紫薯1号’和‘徐紫薯2号’等品种均不适宜在龙岩市推广种植。

Abstract: In order to screen good quality and high yield purple sweet potato varieties which were suitable for planting in Longyan, using a completely randomized block design, six purple sweet potato varieties were introduced and tested in 2014 summer compared with ‘Jinshan 57’. The agronomic characters, economic characters, the fresh tuber yield, dry labor, starch yield, quality and the anthocyanin content were screened and evaluated. The results showed that: two varieties had a good performance among six purple sweet potato varieties. The highest fresh tuber yield was ‘Longjinshu 1’ which was 39.11t/hm2. Its dry matter yield was 9.22 t/hm2.Its starch yield was 5.53t/hm2. Its starch rate was 14.15%. Its taste score was 80 points. Its anthocyanin content was 17.66mg/100g. The second fresh tuber yield was ‘Fushu 24’ which was 36.30t/hm2. Its dry matter yield was 10.82t/hm2 which was increased by 3.32% compared with control. Its starch yield was 7.11t/hm2 which was increased by 6.77% compared with control. Its dry matter rate was 29.81%. Its starch rate was 19.57%. Its taste score was 84.7 points. Its anthocyanin content was 11.95mg/100g. ‘Longjinshu 1’ had the highest fresh tuber yield with adequate characteristics of dry matter rate and anthocyanin content. ‘Longjinshu 1’ was suitable for purple sweet potato varieties of processing dried sweet potato products in Longyan. ‘Fushu 24’ had the higher yield, good eating quality as fresh and highest starch yield. It could be recommended as fresh and purple starch processing type varieties popularized in Longyan. ‘Guangshu 8’ would further observation. ‘Funingshu 3’,‘Ningzishu 1’and ‘Xuzishu 2’ were not suitable for planting in Longyan.
