为了满足福建省不同生态区域对优质、抗病甘薯新品种的需求,福建省农业科学院作物研究所与福建省农业科学院中心实验室于2007年以兰葡萄×南薯88杂交选育而成福薯90号。经过多点试验、省区域试验和生产试验,于2014年5月通过福建省农作物品种审定。该品种生育期135~150d,株型中长蔓半直立,叶色绿带紫,叶型心带齿,茎紫色,薯块纺锤形,薯皮红色,薯肉黄色;单株结薯数2~5个,鲜薯产量41 004.45kg·hm-2,薯干产量10 694.1kg·hm-2,淀粉产量6 695.85kg·hm-2;干物率25.99%,出粉率16.25%,食味评分80.9分,外观评分82.0分;薯块萌芽性好,较耐贮藏,高抗蔓割病。福薯90号属高产、优质、抗病新品种,适宜在福建省大面积推广应用。
In order to meet the different ecological regions in Fujian Province of high-quality, disease-resistant sweet potato new varieties of needs, Fujian Academy of Agricultural Sciences Institute of Crops and Fujian Academy of Agricultural Sciences Central Laboratory in 2007 with blue grape × South 88 hybrid breeding and sweet potato Number 90. After more tests, provincial and regional trials and production tests, in May 2014 through the Fujian Provincial Crop Variety validation. The varieties of growth period of 135 ~ 150d, plant type in the long vines half erect, leaf color green with purple, leaf heart with teeth, purple stems, tuber fusiform, potato red, yellow flesh; The yield of fresh potato was 41 004.45kg · hm-2, the dry yield of potato was 10 694.1kg · hm-2, the yield of starch was 6 695.85kg · hm-2, the dry matter rate was 25.99%, the yield of powder was 16.25%, the taste score was 80.9 Points, the appearance of 82.0 points score; potato germination is good, more resistant to storage, high resistance to CTC. Fushun 90 is a high-yield, high-quality, disease-resistant new varieties, suitable for large-scale application in Fujian Province.
