ZD204为德国KWS公司和中国农科院甜菜研究所联合选育的甜菜二倍体多胚杂交种。该品种适应性强,丰产性突出,块根含糖率较高,属标准偏丰产型品种;抗褐斑病,耐丛根病和根腐病;糖汁纯度高,块根品质好。2000～2001年参加国家甜菜新品种区域试验,在全国三大甜菜产区32个试验点(次)平均根产量53724.3kg/hm2,比对照增产27.9%;平均含糖率15.6%,比对照低0.4度;平均产糖量8263.5kg/hm2,比对照提高26.8%;平均褐斑病病情为1.2级,发病程度与对照相仿;平均根腐病罹病率为0.5%,根腐病发病程度明显低于对照;在丛根病发病地区,ZD204发病率为1.0%～7.7%,对照品种发病率为1.5%～76.6%,发病程度明显低于对照。适宜在东北、华北和西北三大甜菜产区种植推广。
ZD204 is a sugar beet diploid polyembryonic combination developed by the German KWS company and the Chinese Academy of Agricultural Sciences beet research institute. The varieties of adaptability, high yield prominent, higher root sugar content, is a standard type of over-yielding varieties; resistance to brown spot, resistance to rhizomania and root rot; high purity sugar, root quality is good. From 2000 to 2001, it took part in the regional test of new national sugar beet varieties. The average root yield was 53724.3kg / hm2 at 32 test points in three sugar beet producing areas in the country, 27.9% more than the control; the average sugar content was 15.6% 0.4 degrees. The average sugar yield was 8263.5kg / hm2, which was 26.8% higher than that of the control. The average brown spot disease was grade 1.2 and the incidence was similar to that of the control. The average incidence of root rot was 0.5% and the incidence of root rot was significantly lower In the control group, the incidence of ZD204 was 1.0% -7.7% in the areas where rhododendron disease occurred, and the incidence rate of control strains was 1.5% -76.6%. The incidence of ZD204 was significantly lower than that of the control. Appropriate in northeast, north and northwest three beet cultivation areas to promote planting.
