| 摘 要： | 采用单花滴注法将禾谷镰刀菌(Fusarium graminearum)分生孢子接种103份大麦品种（系），鉴定分析不同的大麦品种（系）对赤霉病菌的抗扩展性及其与农艺性状的相关性。结果表明，不同的基因型品种(系)之间抗赤霉病菌扩展性存在显著差异，可划分为高抗（病穗率0～10%）、中抗（病穗率10%～20%）、中感（病穗率20%～40%）和高感（病穗率40%～100%）；大麦抗赤霉病菌扩展性与抽穗期、株高呈显著的负相关，二棱大麦抗扩展性显著高于多棱大麦；供试材料中抗扩展性品种（系）较少，占总数的31.1%, 筛选到10个高抗扩展性的品种（系），分别为：‘Sterling’、‘Metcalfe’、‘Parkhill’、‘ACCA’、‘ND14048’、‘玉环猪尾巴’、‘江山二棱麦’、 ‘黄岩野大麦’、 ‘乐清扁大麦’,、‘上虞红大麦’。

| Abstract: | The barley resistance to spread of Fusarium head blight and its relation to agronomic characteristics were investigated using single floret injection to 103 barley varieties(lines).The results showed there were significant differences among barley genotypes for the resistance to spread of Fusarium head blight,and 103 identified barley varieties(lines) were categorized into four groups: the barley varieties(lines) high resistant to spread of Fusarium head blight(proportion of scabbed spikelet of zero to 10 %... |
