| 中文摘要: |
| 马铃薯晚疫病(late blight)是由致病疫霉(Phytophthora infestans)引起的马铃薯生产中最具毁灭性的病害, 明确晚疫病菌的交配型及对甲霜灵敏感性状况对制定马铃薯晚疫病防治策略具有重要意义。本研究对2011—2013年采自黑龙江省黑河、齐齐哈尔、绥化等马铃薯主产区的晚疫病菌菌株进行交配型及对甲霜灵敏感性测定, 采用对峙培养法对153株晚疫病菌进行交配型检测, 结果表明, A1交配型79株, 占51.63%, A2交配型74株, 占48.37% ; 采用菌落直径法对143株晚疫病菌进行甲霜灵敏感性测定, 结果表明, 83.92%表现高抗, 8.39%表现中抗, 7.69%表现敏感。 |
| 英文摘要: |
| Potato late blight caused by Phytophthora infestans is the most devastating disease in potato production. It is of great importance to clear the mating type of P. infestans and metalaxyl sensitivity for prevention and control of potato late blight. In this study, we measured the mating type and metalaxyl sensitivity of P. infestans strains collected from Heihe, Qiqihar, Suihua and other main potato producing area in Heilongjiang Province during 2011-2013. Mating type determination by dual culture method demonstrated that, among 153 strains, 79 strains were A1 mating type, accounting for 51.63%; 74 strains were A2 mating type, accounting for 48.37%. Metalaxyl sensitivity test by colony diameter method showed that 83.92% were highly resistant among all the 143 tested strains, 8.39% were moderate resistant and 7.69% were sensitive. |
