Abstract: 【Objective】 To screen new varieties of sugarbeet with high quality and disease resistance in Ta′e Reclamation Area in Xinjiang.【Methods】 In the 4-year continuous cropping disease nursery of sugarbeet,a randomized block arrangement design was used to conduct a plot comparison test. Each treatment was repeated 3 times. The local main growing variety Beta796 was used as the control variety. The 9 introduced sugarbeet varieties KWS7748,KWS9968,KWS9899,KWS9962,KWS0066,KWS3410,KWS3354,Beta468,KWS5599 were comprehensively analyzed for their variety adaptability,disease resistance,root yield and sugar yield and other traits.【Results】 The KWS7748 and Beta468 had outstanding performance in disease resistance,root yield,sugar yield and other traits,which were better than the control variety Beta796. The root yield and sugar yield of variety KWS7748 were 43.15% and 43.50% higher than Beta796,and the root yield and sugar yield of Beta468 were 25.83% and 34.47% higher than Beta796,respectively.【Conclusion】 KWS7748,Beta 468 were suitable for cultivation in Ta′e Reclamation Area and could be promoted in the area.
