Abstract:

为探讨以病小穗率与病穗率作为抗性评价指标的精确度,利用单花滴注、孢子液喷雾分别结合土表病麦粒接种的方法,评价了2个大麦重组自交系群体131个株系对赤霉病的抗侵染与抗扩展性。单花滴注接种后调查了第7、14和21天的病情性状,接种后第7天所有株系均感病,病小穗率最低的为1.59%,第21天最高病小穗率为58.91%;孢子液喷雾接种后第21天材料全部感病,其中6棱株系的感病程度高于2棱株系。以病小穗率和病穗率划分赤霉病抗性的分布情况,发现病小穗率更能有效区分株系的赤霉病抗性。相关分析显示,病小穗率、病穗率、禾谷镰刀菌烯醇含量与粒色和穗密度呈显著负相关,而与株高、抽穗期无显著相关。
