摘　　要：甜菜新品种工大甜单2号是利用单胚型不育系与异型保持系单交，获得的不育系再与二倍体授粉系杂交育成的单胚品种。该品种2012～2013年参加黑龙江省甜菜品种区域试验，根产量较对照品种提高6．0％。含糖率结果表现突出，块根含糖率17．0～17．2度，比对照提高1．2度。工大甜单2号在生产试验中，根产量比对照提高14．2％，含糖率达到17．2度，比对照提高1．2度。工大甜单2号含糖率高，适应性广、抗病性强、且丰产性好。The rlew sugalbeet variety HlT-TianDan 2 is a diploid monogermmale steritle hybrid, It was bred by crossing at first a monogerm MS line with a special shaped 0 - type, then by crossing the obtainable MS line with a diploid pollinator. The result of regional test from 2012 to 2013 in Heilonjiang province showed ： sugalbeet variety HlT--TianDan 2 has an outstanding performance in sugar content, the rate of sugar contentin beetroot tubers has reached 17.0 -17.2°S,and were higher than CK 1.2°S,the average root yield were higherthan CK 6.0%. The result of demonstrative trial showed：the rate of sugar content has reached 17.2°S,and were higher than CK 1.2°S,the average root yield were higherthan CK 14.2%. H1T-TianDan 2 has high sugar content and is very good in the suitability of variety. It has resistance to Cercospora leaf spot and root rot. It is good in root yield also.
