摘要：

旨在选育富含胡萝卜素的早熟鲜食型优质甘薯新品种。选用早熟、高产、广适品种‘龙薯9号’作母本，以‘晋甘薯9号’、‘济薯25’、‘红瑶’等18个国内外优良品种（系）混合花粉为父本，运用改良集团杂交法，经实生苗选种后，开展复选、品比和山西省区域试验，进行适应性和抗病性鉴定评价。选育出新品种‘运薯9801’，在省区试中，鲜薯平均产量48528.15 kg/hm2，较对照‘晋甘薯9号’增产13.18%；薯块干物率为25.5%，淀粉含量为19%，鲜薯胡萝卜素含量4.41 mg/100g，蒸煮香甜、口感佳，食味88.7分；抗薯瘟病，中抗黑斑病、蔓割病。‘运薯9801’为富含胡萝卜素的早熟鲜食型特色甘薯品种，优质、高产、适应性广，商品价值突出、适口性好。2020年通过国家非主要农作物品种登记。

Abstract:

The experiment aims at breeding a new sweet potato variety which is rich in carotene, early-maturity, fresh-eating and high-quality. The female parent, ‘Longshu 9’ with early maturity, high yield and wide adaptability, and the male parent, the mixed pollen from 18 domestic and foreign fine varieties including ‘Jinganshu 9’, ‘Jishu 25’, ‘Huangjinqianguan’ and so on, were selected for mass cross. After seeding and selecting the lines, a reselection test, a comparison test, and a regional test in Shanxi were conducted to evaluate the adaptability and the disease resistance identification. The new sweet potato ‘Yunshu 9801’ was bred. In provincial multi-location adaptability test, the average yield of fresh storage root was 48528.15 kg/hm2, which was 13.18% higher than that of the control variety ‘Jinganshu 9’. The dry matter and starch content of the root were 25.5% and 19%, respectively. The carotene content of fresh root was 4.41 mg/100g. The steamed root was sweet with good taste, which taste value was 88.7 scores. ‘Yunshu 9801’ was resistant to bacterial wilt, medium resistance to black rot and Fusarium bulbigenum. The special fresh-eating sweet potato variety ‘Yunshu 9801’ was characterized with high quality, high yield, wide adaptability, outstanding commodity value and good palatability, and conducive to promoting the production of sweet potato and improving the social and economic benefits of sweet potato cultivation. ‘Yunshu 9801’ was registered as a national non-major crop variety in 2020.
