In the sweetpotato variety regional trial of Jiangsu Province during 2007 - 2008, average fresh storage root yield was 30 185.3 kg/hm2 ; average dry matter content was 29.26% ; average dry storage root yield was 8 868.7 kg/hm2. In the sweetpotato variety production test of Jiangsu Province, average fresh storage root yield was 30 683.9 kg/hm2 ; average dry storage root yield was 9 399.0 kg/hm2. Multi-location sampling analysis in the regional trial indicated that the anthocyanin content in fresh storage roots was 104.6 μg. Xuzishu 2 was approved by Crop Variety Approval Committee of Jiangsu Province in March 2010, which exhibited high fresh storage root yield, sweet taste, high anthocyanin contem, good commodity, root rot resistance, and was tolerant to moisture and easy to store. Therefore, Xuzishu 2 is a high-quality purple-fleshed sweetpotato variety suitable for consumption and food processing, which should be cultivated in medium- and high-fertility fields with management procedures of suitable high density, early planting and early harvest.展开更多
