甜菜品种BETA218引种鉴定

Introduction and Identification of Sugar Beet BETA 218

【目的】引进适应新疆糖区种植的丰产、高糖、抗病甜菜品种,在生产中应用推广。【方法】在多点引进试验鉴定的基础上,筛选优良品种参加新疆维吾尔自治区甜菜品种区域试验、区试试验生产示范,由新疆维吾尔自治区农作物品种审定委员会审定命名。【结果】BETA218于2003~2004年参加自治区甜菜品种区域试验,块根产量、含糖率和产糖量分别为81 136.5 kg/hm2、15.36%和12 396.0 kg/hm2,分别比对照提高3.5%、1.65°、16.2%;经抗丛根病性鉴定,两年平均病级为1.5级,病指为29.08%,抗性为抗;2004年参加生产试验,块根产量为84 994.5 kg/hm2,含糖率为16.46%。于2005年4月通过新疆维吾尔自治区农作物品种审定委员会审定。被命名为新引BETA218。【结论】BETA218丰产性强,含糖率较高,抗丛根病,中抗甜菜褐斑病、白粉病,适应性和稳定性优良,属丰产抗丛根病甜菜杂交品种。通过甜菜品种区域试验和生产试验,该杂交种适应于在新疆伊犁、博乐、焉耆、奇台等糖区种植。
