红薯是我省主要的粮食作物,历年种植面积约1800万亩。单产却一直徘徊在2000斤左右的水平上,远远没有发挥出它高产、稳产的特性。究其原因,除大面积栽培条件较差外,主要是品种退化、混杂严重,至今我省胜利百号的面积还占40％,严重地影响了红薯产量的提高。因此,选育和推广高产、优质、抗病的红薯新品种是目前生产上急待解决的问题之
Sweet potato is the main food crops in our province, the calendar year planting area of about 1800 mu. Yields have been hovering around the level of about 2,000 pounds, far from playing its high yield, stable yield characteristics. The reason, in addition to a large area of poor cultivation conditions, the main species degeneration, mixed serious, so far our province Shengli Hundreds area also accounted for 40%, seriously affected the sweet potato yield increase. Therefore, the breeding and promotion of high-yield, high-quality, disease-resistant new varieties of sweet potato is the production of the urgent solution to the problem
