摘　　要：为鉴选出适合在内蒙古东部干旱区种植的甜菜新品种,2019年在内蒙古自治区阿荣旗,以品种KWS1176为对照,对21个国内外甜菜新品种形态性状及田间表现、块根产量及含糖率、病害发生情况、灰分含量等指标进行了比较分析。结果表明:降雨量对甜菜的各项指标影响较大。HI1380、KWS7125、KWS2314、KWS1479、BETA5665、CN0417共6个品种块根产量高于60.0 t·hm^(-2),其中品种HI1380的块根产量最高,达到70.8 t·hm^(-2);各甜菜品种块根含糖率差异较大,最高达16.8%,比对照品种KWS1176增加1.6%,最低的仅为12.7%。22个参试品种均发生了轻微的褐斑病和黄化毒病,但都未发生丛根病和白粉病,但7个品种发生了严重的根腐病。钾含量最低的品种是CN0417,钠含量最低的品种为HDTY191,α-氮含量最低的品种为ST13539。综合鉴选,评定品种HDTY191、HDTY192、NT981101、KWS1479、KWS2314、KWS1176表现较好,更适宜在内蒙古东部干旱地区种植。In order to select suitable sugar beet varieties for cultivation in the arid area of eastern Inner Mongolia,we used the variety KWS1176 as the control and compared the morphological traits,root yields,sugar contents,disease occurrences and ash contents of 22 new sugar beet varieties in Arong Banner of Inner Mongolia.The results showed that the traits of sugar beet were greatly affected by rainfall.The root yields of HI1380,KWS7125,KWS2314,KWS1479,BETA5665 and CN0417 were higher than 60.0 t·hm^(-2),among them variety HI1380 had the highest yield of 70.8 t·hm^(-2).The highest sugar content of sugar beet variety was 16.8%,1.6%higher than that of control,while the lowest sugar content was only 12.7%.Mild brown spot and chlorosis occurred in 22 varieties,while none of them had clumps and powdery mildew.Seven varieties had serious root rot.The variety with lowest potassium content,sodium content andα-nitrogen content was CN0417,HDTY191,and ST13539,respectively.The varieties HDTY191,HDTY192,NT981101,KWS1479,KWS2314 and KWS1176 exhibited better growth performance and were more suitable for planting in the arid area of eastern Inner Mongolia.
