摘　　要：紫莳药18是由浙江省台州市传统山药产地的特色地方品种紫莳药变异株经过系统选育而成的山药新品种。该品种单株结薯数一般1~2个,块茎圆柱形,长度26.9 cm左右,直径8.3 cm左右,单株块茎质量1.1 kg左右,块茎表皮颜色褐色,须根少,果肉紫色,肉质较粉,蒸煮易熟烂,食味好。干物质、淀粉、可溶性糖、蛋白质含量(w,后同)分别为32.3 g·100 g^(-1)、21.1 g·100 g^(-1)、0.9 g·100 g^(-1)、2.41 g·100 g^(-1)。在田间炭疽病抗性强于对照。一般667 m^(2)产量1700 kg左右,适宜浙江台州及类似地区种植。2023年4月通过浙江省农作物品种认定委员会认定。Zishiyao 18 is a recently released variety of Chinese yam that was selected and developed from a mutant of the local characteristic cultivar Zishiyao in Taizhou,Zhejiang province.Typically,its each plant yields one to two cylindrical tubers,which are approximately 26.9 cm in length and 8.3 cm in diameter.The tubers weight of a single plant average approximately 1.1 kg with brown skin,few fibrous roots,and purple-colored flesh that is notably powdery.The contents of dry mass,starch,soluble sugar,and protein in the tuber were recorded as 32.3 g·100 g^(-1),21.1 g·100 g^(-1),0.9 g·100 g^(-1),and 2.41 g·100 g^(-1),respectively.The variety exhibits enhanced field resistance to anthracnose compared with Zishiyao.Generally,667 m2 yield is approximately 1700 kg.Zishiyao 18 is well-suited for cultivation in Taizhou,Zhejiang,and similar regions.
