介绍了甘薯“渝苏1号”的生产力和抗黑斑病性的鉴定结果.“渝苏1号”鲜薯平均亩产1795.5kg,鲜薯最高亩产达3250.0kg.薯干平均亩产588.7kg,淀粉平均亩产413.7kg,鲜藤叶平均亩产2286.5kg,地上地下部总产量为每亩3905.9kg,分别比对照“农大红”增产24.86%,72.02%,35.45%,6.15%.“渝苏1号”薯块人工接种黑斑病菌后,病斑直径比“徐薯18”小,深度比“徐薯18”和“农大红”浅.薯块在贮藏期间自然感染黑斑病的发病率比“农大红”和“徐薯18”低.
The productivity and anti-black spot identification results of sweet potato “Yu-Su-1” were introduced.The average yield of fresh potato in Yusu No.1 was 1795.5kg and the highest yield of fresh potato was 3250.0kg.The average yield per mu of potato was 588.7 kg, average yield per mu of starch was 413.7kg, fresh vine yield was 2286.5kg per mu and total ground above ground was 3905.9kg per acre, which increased by 24.86%, 72.02%, 35.45% and 6.15% respectively than the control. Yushu 1 “potato block was inoculated with Alternanthera philoxeroides, its lesion diameter was smaller than that of” Xushu 18 “and its depth was shallower than that of” Xushu 18 “and” Nongdahong “.The tubers naturally infected with black spot during storage The incidence rate is lower than that of ”Nong Da Hong“ and ”Xu Shu 18".
