通过对5个马铃薯品种的品质、产量、抗病性、经济产出等特性的比较试验,筛选适合湖南冬闲田栽培推广的马铃薯新品种。结果表明:在相同的栽培条件下,陇薯7号和LK99相对于费乌瑞它(Favorita)分别增产41.28%和29.80%。综合看来,陇薯7号和LK99产量、抗病性和综合性状较好,适合在湖南冬闲田推广。紫色马铃薯黑金刚产量偏低,但该品种富含花青素,营养价值高,干物质含量高。费乌瑞它作为湖南冬闲田传统品种,生育期短,上市早,产量高,干物质含量高,但是抗病性差,建议今后适度发展。
By comparing the characteristics of five potato varieties such as quality, yield, disease resistance, economic output and other characteristics, the new potato varieties suitable for the promotion and cultivation of winter fallow fields in Hunan were screened out. The results showed that under the same cultivation conditions, Longshu 7 and LK99 increased yield by 41.28% and 29.80% respectively compared with Favorita. Comprehensive view, Longshu 7 and LK99 yield, disease resistance and comprehensive traits better, suitable for promotion in winter garden in Hunan. Purple Potato Black Diamond production is low, but the variety is rich in anthocyanins, high nutritional value, high dry matter content. Feirui it as a winter leisure field in Hunan traditional varieties, short growth period, early market, high yield, high dry matter content, but poor disease resistance, the proposed moderate development in the future.
