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 0一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 varie-ty 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%.HlT—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 .
