国家甜菜区试品种在甘肃河西走廊丰产与稳定性及抗病性评价

High Yield Sutability and Resistance Evaluation of Regional Test Sugarbeet Varieties in Hexi Corridor of Gansu Province

用品种稳定性参数及高稳系数(HSC),对2004～2005年参加国家甜菜区试中的5个品种在甘肃武威市黄羊镇和酒泉地区的试验结果进行了综合分析,结果表明:BTS356的丰产、稳产性好,两年平均根产量和产糖量分别较对照陇糖2号增产40.62%和39.94%,差异达极显著水平,含糖率18.73%;对黄化病、白粉病、立枯病的抗性优于对照,具有较高的应用价值,适宜在甘肃省河西走廊生态条件下推广种植。

Data of 5 sugarbeet varieties for regional experimentation in Jiuquan and Wuwei areas from 2004 and 2005 were analyzed with the parameter of stability and HSC. The results indicated that： the variety BTS356 showed a high root yield and stability, the average root yield and sugar yield for two years increased by 40.62% and 39.94% respectively, in comparison with Longtang2 （CK）. The difference reached significant level. The sugar content was 18.73%. The resistance to beet yellow virus, powdery mildew and seedling blight was superior in comparison with the CK. So it has higher application value and fit to extend plant under the ecosystem condition of the west corridor of Gansu province.
