抗病高淀粉甘薯新品种徐薯26是中国农业科学院甘薯研究所以徐781为母本,通过集团杂交放任授粉、多年多点综合鉴定选育而成。该品种2009年通过国家甘薯新品种鉴定,鉴定编号为国品鉴甘薯2009003。对徐薯26的形态特征、品质性状、抗病性、生产力和产量形成的生理特点等进行了研究,结果表明:徐薯26全生育期长势平稳,薯干品质和食味较好,抗根腐病和蔓割病,薯干和淀粉产量与徐薯18相比增产极显著,生长后期薯块干物质积累较快,经济系数较高,适宜早栽和密植。
Xushu 26, a disease-resistant, high-starch-sweetpotato variety, is a sweet-potato research institute of the Chinese Academy of Agricultural Sciences using Xu 781 as its female parent, which is allowed to flourish through group hybridization and multi-year comprehensive identification. The variety in 2009 through the national identification of new varieties of sweet potato, identification number sweet potato 2009003. The morphological characteristics, quality traits, disease resistance, productivity and the physiological characteristics of the yield formation of Xushu 26 were studied. The results showed that: Xushu 26 grew steadily during the whole growth period, its quality and taste were better, Soybean disease and creeping disease, tuber yield and starch yield increased significantly compared with the Xushu 18, the rapid growth of late dry matter accumulation of tubers, a higher economic coefficient, suitable for early planting and close planting.
