甜单一号其母本四倍体甜单４０１为由ＰＥＫ品种通过镜检提纯及经含糖率、抗病性状等多轮选择，表现性状整齐、丰产性强、其父本二倍体甜２０９为高糖、抗病的自交系，母父本以３：１自然杂交选育而成。试验结果表明，甜单一号振产量、含糖率与产糖量分别比对照品种提高１１．７％、０．０８度与１２．２７％。甜单一号为标准偏丰产型、单粒、多倍体杂交种，适宜机械化精量点播及纸筒育苗移栽，适应性广且丰产、稳定性强，已在黑龙江、新疆、内蒙古等省（区）开始推广种植。
The sweet single number of its tetraploid sweet single 401 for PEK varieties by microscopic examination and sugar content, disease resistance and other round of selection, performance traits, high yield, and its male parent diploid sweet 209 For high sugar, disease-resistant inbred lines, the mother of the natural selection of 3: 1 breeding. The results showed that the yield of sweet single number, sugar content and yield of sugar were increased by 11.7%, 0.08 and 12.27% respectively compared with the control. Sweet single number for the standard yield type, single, polyploid hybrids, suitable for mechanized precision on-demand and transplanting paper tube seedling, wide adaptability and high yield, strong stability, has been in Heilongjiang, Xinjiang, Inner Mongolia and other provinces ( District) began to promote planting.
