中文摘要 | 用人工接種方法檢定來自中國大陸的26個苜蓿品種對黃萎病菌(Verticillium albo-atrum) 的罹病性反應。 結果顯示除了鄂旗 (E Qi) 品種具有中等抗病性外,其餘 26 個品種均呈現高度感病性,與北美洲及歐洲等對照品種相較,鄂旗品種之抗病性與 Vertus( 歐洲品種 ) 相近,但是比 Barrier( 加拿大品種 ) 為差。苜蓿黃萎病在中國與臺灣尚無報 導,鑑於本病害容易經由種子與有病植株莖幹傳播。在無病地區宜將本病納入檢疫對象,以 杜絕此一新病害之侵入。 |
英文摘要 | Twenty six alfalfa cultivars (25 Medicago sativa and one M. falcata) from China were compared to the seven standard cultivars from North America and Europe for resistance to Verticillum wilt caused by Verticillium albo-atrum. Except for the cultivar E Qi, all 25 Chinese cultivars were susceptible to Verticillium wilt with low numbers of resistant plants (less than 21.7% in the population of each cultivar) and high disease severity index (greater than 3.43). The cultivar E Qi was moderately resistant to Verticillium wilt with 43.4% of resistant plants. which was similar to the Swedish cultivar Vertus (43.3%) but lower than the Canadian cultivar Barrier (60.2%). Since there is no report of Verticillium wilt of alfalfa in China or Taiwan, the susceptible nature of Chinese alfalfa cultivars suggests that a regulatory measure may be required to prevent this destructive disease from entering into disease free regions via pathogen- infected alfalfa seed or hay. |
