东南沿海沙地紫肉甘薯新品种引种试验

Seed Introduction Test of Purple-fleshed Sweet Potato in the Southeast Coast of China

为鉴定筛选适合于东南沿海沙地种植的高产、优质紫肉甘薯新品种,引进福薯34、福宁紫4号、龙紫12号、金薯17、莆紫薯18等5个紫肉甘薯品种,在福建长乐滨海沙地进行了比较试验。结果表明,引进品种的产量、品质等表现存在差异,其中福宁紫4号鲜薯产量最高,每667m^(2)产量达2901.5 kg,比对照增产30.5%,龙紫12薯干产量最高,达753.5 kg,比对照增产13.98%。福宁紫4号和金薯17两个品种在鲜薯产量、品质、薯形、结薯习性、商品性等综合表现较好,可在当地沙地区域大面积推广。
