| 【目的】筛选适合在海南夏秋高温季节种植的优质菜用甘薯品种。【方法】试验选用 10 个菜用甘
薯品种进行 2 年试种评估。通过对参试品种农艺性状和抗病性调查，叶色值和干物质率测定，营养品质和食味
进行评价。【结果】总产量上，海大 7798 和黔菜薯 2 号表现较好，均显著高于对照福薯 7-6；在营养品质方面，
EC15 硝酸盐含量最低，黔菜薯 2 号的可溶性糖含量（99.42 mg/g）和维生素 C 含量（13.92 mg/g）最高，薯绿 2
号可溶性蛋白含量最高；在抗病性调查上，广菜薯 7 号、薯菜 14-7、海大 7798 和黔菜薯 2 号评价较好；在食味
评价中，广菜薯 7 号和桂薯菜 14-7 综合评分较高。【结论】综合试验结果，海大 7798、黔菜薯 2 号、广菜薯 7
号和桂薯菜 14-7 号产量较高、口感风味良好、营养品质丰富，均适宜在海南夏秋季种植生产。 |

| 【Objective】The study was to select high-quality vegetable sweet potato varieties that suitable for
production in Hainan in hot summer and autumn.【Method】10 vegetable sweet potato varieties were selected for trial
and evaluation for 2 years. Through the investigation of agronomic traits and disease resistance on the tested varieties, the
determination of leaf color value and dry matter rate, and the evaluation of nutritional quality and taste were carried out.
【Result】In terms of total yield, Haida 7798 and Qiancaishu 2 were significantly higher than that of the control Fushu
7-6; in terms of nutritional quality, EC15 had the lowest nitrate content, Qiancaishu 2 had the highest soluble sugar content
and vitamin C content with 99.42 mg/g and 13.92 mg/g, respectively, while Shulv 2 had the highest soluble protein content;
in terms of disease resistance, Guangcaishu 7, Guishucai 14-7, Haida 7798 and Qiancaishu 2 were the best varieties; in
the evaluation of the taste, Guangcaishu 7 and Guishucai 14-7 had higher comprehensive scores. 【Conclusion】From the
results mentioned above, it can be concluded that, Haida 7798, Qiancaishu 2, Guangcaishu 7 and Guishucai 14-7 have
higher yields, good taste and flavor, and rich nutritional quality, which are suitable for planting and production in Hainan in
summer and autumn. |
