摘　　要：为了满足多用途甘薯品种的市场需求,采用徐薯22为母本,浙薯20为父本开展杂交选育,育成兼用型品种浙薯33。该品种既有较高的常规鲜薯产量和淀粉产量,又有较好的早结薯性。具有峰值粘度高、崩解值和回生值高、糊化温度低的淀粉RVA特性,同时薯块蒸熟后麦芽糖和可溶性糖含量高,适用于鲜食、淀粉加工和薯脯加工。块根β-淀粉酶活性高、耐热性好,可提早收获用作鲜食和薯脯加工。耐贮藏性好,高抗黑斑病,中抗蔓割病。浙薯33是一个结薯早、优质、耐贮藏的多用途品种,适宜在浙江省及长江中下游流域种植。In order to meet the market demand of multi-purpose sweet potato varieties,a dual-purpose variety Zheshu 33 was bred by crossing Xushu 22 as female parent and Zheshu 20 as male parent.Zheshu 33 not only had high yield of fresh storage root and starch under conventional cultivation,but also had early storage root formation.This variety is suitable for table food,starch processing,and preserved sweet potato processing because it possessed the RVA characteristics of starch,such as high peak viscosity,high breakdown value and setback value,and low pasting temperature.At the same time,the steamed storage root had a high content of maltose and soluble sugar.The variety also has some other characteristics such as good storability,high resistance to black rot and medium resistance to fusarium wilt.Therefore,Zheshu 33 is a multi-purpose variety with early maturity,high quality and good storability,and suitable for planting in Zhejiang Province and the middle and lower reaches of the Yangtze Plain.
