摘要： 为筛选适宜连城县种植的加工专用型紫色甘薯新品种，采取随机区组设计，以‘龙岩7-3’为对照，2012年秋季引进5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、薯块的营养品质、甘薯干和油炸脆片产品的加工品质等方面进行筛选鉴定。结果表明：各品种表现不同。其中，‘伟祥1号’鲜薯产量最高达41.9 t/hm2，比对照‘龙岩7-3’增产25.8%。‘济薯18号’鲜薯产量为31.6 t/hm2，与‘龙岩7-3’相当。‘济薯18’和‘伟祥1号’加工的甘薯干，不仅在工艺稳定性、口感、色变等综合指标，均接近‘龙岩7- 3’，而且在产品的形态、色泽、透明度、口感和质地等方面均表现优异，可作为加工甘薯干的紫薯品种。‘济薯18’和‘伟祥1号’加工的油炸薯片，含油率适中，膨化度高，产品品质与对照‘龙岩7-3’相当，可作为加工油炸薯片的紫薯品种。‘福薯9号’、‘泉紫薯1号’和‘宁紫薯1号’的薯形美观，营养品质高，食味粉香，适合优质鲜食和加工甘薯全粉用。

Abstract: In order to screen good quality and high yield purple sweet potato varieties which were suitable for special processing in Liancheng County, using a random block design, five purple sweet potato varieties were introduced and tested in 2012 autumn compared with‘Longyan 7-3’. The agronomic characters, economic characters, nutritional components, processing quantity of dried sweet potatoes and fried chips were evaluated. The results showed that: the highest fresh tuber yield was‘Weixian No.1’which was 41.9 t/hm2. Its yield increased by 25.8% compared with control. The fresh tuber yield of‘Jishu No.18’was 31.6 t/hm2. Its yield was close to control. The process stability, taste, color and other comprehensive index of dried sweet potato products with‘Weixian No.1’and‘Jishu No.18’were close to control and its morphology, color, transparency, taste and texture and so on were excellent.‘Weixian No.1’and‘Jishu No.18’were suitable for purple sweet potato varieties of processing dried sweet potato products. The fried chips with‘Weixian No.1’and‘Jishu No.18’had moderate oil content, the higher swelling degree, its products quality were close to control.‘Weixian No.1’and‘Jishu No.18’were suitable for purple sweet potato varieties of processing fried sweet potato chips products.‘Fushu No.9’,‘Quanzi No.1’and‘Ninzi No.1’had the characters of fine exterior, high nutritional quality and high dry rate, which were suitable for purple sweet potato varieties of fresh-eating and food processing sweet potato whole powder.
