摘　　要：甜单303是甜菜遗传单粒型多倍体杂交种。该品种在2002～2003年的黑龙江省甜菜品种区域试验中,16点次的平均块根产量为39877.8kg/hm^2,比对照种甜研303和甜单二号平均高12.16%;平均含糖率16.47%,比对照低0.46度;平均理论产糖量为6667.5kg/hm,比对照高8.77%。在2003年的黑龙江省甜菜品种生产示范试验中,4个试验点平均块根产量为41273.9kg/hm^2,比对照种甜单二号提高17.88%;平均含糖率16.89%,比对照低20.52度;平均理论产糖量为7135.6kg/hm^2,比对照高14.18%。该品种抗褐斑病性与对照种相仿。2004年初通过黑龙江省农作物品种审定委员会审定命名。The Tiandan303 is a genetic monogerm polyploid sugar beet hybrid. In Heilongjiang sugar beet variety trial in 2002 and 2003 (total sixteen trial area for two years), the mean root yield was 39877.8kg per ha and increased by 12.16% in comparison with the Tiandan2; the mean sugar content was 16.47% and decreased by 0.46°S; the mean sugar yield 6667.5kg per ha and increased by 8.77%. In Heilongjiang demonstration experiment in 2003 (four trial areas), the mean root yield was 41273.9kg per ha and increased by 17.88% in comparison with Tiandan2; the mean sugar content was 16.89% and decreased by 0.52°S; the mean sugar yield 7135.6kg per ha and increased by 14.18%. Its leaf spot resistance is similar to the Tiandan2. It was registered as a new variety in 2004 by Heilongjiang Crop Committee.
