摘　　要：利用航天育种卫星搭载的甜菜单胚雄性不育系和二倍体品系,从材料中找到优良的变异株,利用变异株配制了8个杂交组合,从中筛选出优良杂交组合甜航单0919。甜航单0919是我国首个利用航天诱变技术研制的二倍体单胚杂交种,杂种优势强,丰产性好,含糖率高,较抗褐斑病和根腐病,克服了单胚品种含糖低、抗性差的缺点。The excellent variant individuals were screened from space-mutated seeds of monogerm male sterility lines and diploid lines carried by space-flown breeding satellite. They were used to make 8 cross combinations with HTD0919 as the best. HTD0919 was the first diploid monogerm sugarbeet hybrid by the space mutation techuology. The results from Heilongjiang regional and production trials show that HTD0919 has strong heterosis, good yielding ability, high sugar content, and high resistance to leaf spot and root-rot diseases. It has overcome the probelems of low sugar content and disease susceptibility connected to monogerm sugarbeets.
