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。
Sugar beet male sterile single diploid hybrid sweet single 304, is a single embryogenic male sterile line TB7-CMS as the female parent diploid embryo sweet 217-8 as the male parent, by 41: And into. From 2003 to 2004, they took part in the provincial regional experiment. The results showed that the average root yield was 42674.7 kg / hm2 and the average sugar content was 17.48%, which was 12.5% and 0.20% higher than that of the sweet potato variety No.2. In 2005 to participate in the provincial demonstration pilot production, in February 2006 through the Heilongjiang Provincial Crop Variety Approval Committee named. The variety of tuberous high yield, high sugar content, resistance to brown spot, resistant to root rot. Suitable for mechanized seeding and paper tube seedling transplanting. More experiments show that the varieties suitable for planting in Heilongjiang, Inner Mongolia, Xinjiang and other main sugar beet producing areas.
