摘要
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。
Tiandan-1 was developed with female parent tetraploid Tiandan 401 which came fromC.V. PEK,to give purification and rejuvcnation,multiple circle selection for sugar content,di-sease asistance and symmetrical, the yiclding ability were higher,the male parent is diploidTian 209 which is selfing line with high sugar and discase resistance,the female and male par-ent is 3:1 for natural crossing, the test results have shown that the root yield, sugar contentand sugar yield were higher than CK, that is 11.7%,0.08% and 12.27% increasing resp , thisculuvar is NE-type,monogerm,polyploid hybrid、it can give the precision drilling and cantransplanting with paper-pot nursery and it has widely adaptability,and can get high yiel-ding and high stability,which recommanded to plant in Heilongjiang,Xinjiang and InnerMengolia etc.
