抗（耐）甜菜丛根病新品种中甜—双丰317号（张甜301）是以二倍体抗（耐）丛根病品系抗1和抗褐斑病性强、含糖较高的四倍体双丰415杂交而成的普通多倍体甜菜新品种。该品种块根产量高、含糖中等、工艺品质好、抗（耐）丛根病及褐斑病性强，在1994～1995两年国家“八五”科技攻关抗（耐）甜菜丛根病品种联合区试中达标，平均块根产量为2570.8kg／亩，比对照品种增产512．6％，含糖率（14．61％）提高3．98度，产糖量为359．3kg／亩，比对照增加1036.4％。在内蒙古、宁夏、甘肃、新疆等试验点表现出较强的耐丛根病性。
Shuangfeng 317 (Shuangfeng 301), a new variety resistant to resistance to betaine, is characterized by its high resistance to resistance to Rhizoctonia solani 1 and its resistance to brown spot and high sugars Tetraploid Shuangfeng 415 hybrid common polyploid beet new varieties. The varieties of high root yield, moderate sugar content, good process quality, anti (resistant) Rhizoctonia and brown spot strong, in 1994 ~ 1995 two years of the national “Eighth” science and technology resistant (tolerance) In the united zone test, the average yield reached 2570.8kg / mu, yielding 512.6% more than that of the control varieties, increasing the sugar content (14.61%) by 3.98 degrees and the yield of sugar to 359.3kg / mu Control increased by 1036.4%. In Inner Mongolia, Ningxia, Gansu, Xinjiang and other experimental sites showed strong tolerance to rhizomania.
