摘要

摘要: 甘薯新品种‘徐薯32’是以品质性状良好的‘徐薯55-2’为母本、‘红东’为父本，经有性杂交培育而成。该品种于2015年通过河南省农作物品种审定委员会审定。通过对‘徐薯32’农艺性状特征、生产力、抗病性、品质性状等进行研究，结果表明：‘徐薯32’地上部短蔓，薯块萌芽性好，耐贮藏，熟食口感佳；抗黑斑病，中抗根腐病与茎线虫病；鲜薯产量与对照‘徐薯22’相当，薯干和淀粉产量较对照分别增产15.24%和18.99%；‘徐薯32’块根主要营养物质含量均高于‘徐薯18’，其淀粉最高粘度值与崩解值较‘徐薯18’分别高6.52%和12.40%，糊化温度则略低于‘徐薯18’；淀粉粒径表面积与体积分布呈三峰、数目分布呈单峰，三类分布中淀粉颗粒总平均粒径均低于‘徐薯18’，降低幅度分别为12.22%、13.18%和2.22%。因此，‘徐薯32’具有良好的农艺性状与品质特性，可为鲜食型甘薯品种改良和应对市场需求奠定基础。

Abstract: A new high-quality sweetpotato cultivar ‘Xushu 32’ was derived from ‘Xushu 55-2’ and ‘Beniazuma’ parental material with very different genetic backgrounds and good quality characteristics by natural sexual breeding. It was approved by the Henan Provincial Crop Varieties Appraisal Committee in 2015. We studied the agronomic, production, disease resistance and quality characteristics of ‘Xushu 32’. Results showed that ‘Xushu 32’ had a short stem, strong sprout ability, strong storage ability, good taste, resistance to black rot, and medium resistance to stem nematodes and root rot. Fresh storage root yield of ‘Xushu 32’ was equivalent to that of ‘Xushu 22’. Dry storage root yield and starch yield were 15.24% and 18.99% higher, respectively, than that of ‘Xushu 22’. Main root nutrients were higher than that of ‘Xushu 18’. Its starch peak viscosity (PKV) and breakdown viscosity (BDV) were 6.52% and 12.40% higher, respectively, than that of ‘Xushu 18’. Starch granule distribution was different among surface area, volume, and number frequency, with the former two distributed in a triple peak pattern and the latter in a single peak pattern. The average granule diameters of ‘Xushu 32’ in the three granule distributions mentioned above were 12.22%, 13.18%, and 2.22% lower, respectively, than that of ‘Xushu 18’. In brief, ‘Xushu 32’ is a good sweetpotato cultivar for table use with excellent properties and good quality characteristics, which will satisfy market requirements and improve sweetpotato varieties.
