【摘要】 HDTY02是以Dms2-1为母本,WJZ02为父本,采用我国自主培育的新型细胞质雄性不育系通过杂交方法选育而成的单胚高糖型甜菜新品种。该品种2011—2012年两年的黑龙江省区域试验和2013年的生产试验平均公顷产量53087.7kg和49160.3kg,分别较对照品种增产4.9%和10.8%;平均含糖17.4%,分别较对照品种增加0.9度和1.2度;公顷产糖量分别为9259.2kg和8504.0kg,分别较对照品种增加10.7%和18.8%。该品种表现抗褐斑病和耐根腐病,适宜在黑龙江省地区种植。更多还原

【Abstract】 A new monogerm and high sugar content sugarbeet variety, HDTY02 was bred by crossing a monogerm diploid male sterile sugarbeet line Dms2-1as female parent and a monogerm diploid pollination sugarbeet line WJZ02 as male parent. In Heilongjiang regional sugarbeet test from 2011 to 2012 and production demonstration test in 2013, the mean root yield of HDTY02 were 53087.7 kg/ha and 49160.3 kg/ha, increased by4.9% and 10.8%; mean sugar content were same 17.4%, increased by 0.9 and 1.2 degree; mean sugar yield were9259.2 kg/ha and 8504.0 kg/ha, increased by 10.7% and 18.8%, respectively, in comparison with control varieties. HDTY02 is characterized by resistance to leaf spot, and tolerance to root rot disease. The variety is suitable to plant in Heilongjiang area.更多还原
