摘　　要：甜菜雄性不育单胚二倍体杂交种甜单304,是由单胚雄性不育系TB7-CMS为母本,以二倍体多胚品系甜217-8为父本,按41∶比例杂交而成。2003～2004年参加省区域试验,其结果平均根产量42674.7 kg/hm2,平均含糖率17.48%,比对照品种甜单2号提高12.5%和0.20度。2005年参加省生产示范试验,2006年2月通过黑龙江省农作物品种审定委员会命名。该品种块根丰产性好,含糖率较高,抗褐斑病、耐根腐病。适于机械化播种和纸筒育苗移栽。多点试验表明,该品种适宜种植在黑龙江、内蒙古、新疆等甜菜主产区。Tiandan304, a new cytoplasmic male sterile monogerm diploid sugarbeet variety, from a cytoplasmic male sterile monogerm diploid line TB7-CMS as the female parent with a polygerm diploid line 217-8 as the male parent was crossed through natural pollination by 4：1. In the Heilongjiang province sugarbeet variety trial from 2003 to 2004, the mean root yield, sugar content were 42674.7 kg/ha, 17.48 %, increased by 12.5% and 0.20°S, respectively. It was tested in the Heilongjiang province demonstration experiment in 2005, and registered as a new variety in 2006 by Heilongjiang Crop Committee. The variety have shown the high yield and comparatively high sugar content, resisctant to leaf spot and tolerant to root rot, and fits for mechanical seeding and paper-pot nursery seedling. The different area experiments showed that the variety was suitable to plant in the Heilongjiang, the Inner Mongolia and the Xinjiang autonomous regions.
