新疆塔额垦区优质抗病甜菜新品种适应性评价

Adaptability evaluation of new varieties of sugarbeet with high quality and disease resistance in Ta′e Reclamation Area in Xinjiang

【目的】筛选适宜新疆塔额垦区种植的优质抗病甜菜新品种。【方法】在甜菜4年连作病圃采用随机区组排列设计进行小区对比试验,每个处理3次重复,以当地主栽品种Beta796为对照品种,对引进的9个甜菜品种KWS7748、KWS9968、KWS9899、KWS9962、KWS0066、KWS3410、KWS3354、Beta468、KWS5599进行品种适应性及抗病性、根产量、产糖量等性状的综合分析。【结果】品种KWS7748、Beta468的抗病性、根产量、产糖量等性状表现突出,均优于对照品种Beta796。品种KWS7748根产量和产糖量分别比对照品种Beta796高43.15%和43.50%,品种Beta468根产量和产糖量分别比对照品种Beta796高25.83%和34.47%。【结论】品种KWS7748、Beta468较适宜塔额垦区种植,可以在该地区示范推广。

【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.
