徐紫薯2号系江苏徐州甘薯研究中心从AIS35-2×徐薯22-5的杂交后代中选育出的一个优质紫肉甘薯新品种。在2007—2008年的江苏省甘薯品种区域试验中,平均鲜薯产量为30 185.3 kg/hm2,平均干物率29.26%,平均薯干产量8 868.7 kg/hm2;生产试验中,平均鲜薯产量为30 683.9 kg/hm2,平均薯干产量9 399.0 kg/hm2;区域试验多点取样分析可知,鲜薯块花青苷含量104.6μg/g。该品种于2010年3月通过江苏省农作物品种审定委员会鉴定,鲜薯产量高,熟食味甜,富含花青苷,商品性好,抗根腐病,较耐湿和耐贮藏,是一个适于食用及食品加工用的紫肉甘薯品种,适宜在中等肥力以上的田块种植,应合理密植早栽早收。
Xuzheyou 2 was a new high-quality purple sweet potato variety bred from the hybrid progeny of AIS35-2 × Xushu 22-5 by the research center of sweet potato in Xuzhou, Jiangsu Province. In 2007-2008 regional trials of sweet potato varieties in Jiangsu Province, the average fresh potato yield was 30 185.3 kg / hm2, the average dry matter rate was 29.26% and the average dry potato yield was 8 868.7 kg / hm2. In the production experiment, the average fresh potato yield was 30 683.9 kg / hm2, and the average yield of dried potato was 9 399.0 kg / hm2. According to the multi-point sampling analysis in the regional experiment, the anthocyanin content of fresh potato was 104.6 μg / g. The varieties in March 2010 by the Jiangsu Provincial Crop Variety Certification Committee identified fresh potato yield, sweet delicacies, rich in anthocyanins, good merchandising, resistance to root rot, more moisture and storage resistance, is a suitable Edible meat and sweet potato varieties for food processing, suitable for planting above the field of medium fertility, should be reasonable close planting early harvest.
