摘  要:
从梨黑星病(Venturia nashicola)病原菌、发病条件、抗病机制、抗性遗传等方面对梨黑星病的研究进展进行了系统综述。梨黑星病的病原菌有2种,侵染中国梨的为纳雪黑星菌(Venturia nashicola Tanak et Yamamota),侵染西洋梨的为梨黑星菌(Venturia pirina Aderh);梨对黑星病的抗性呈显性遗传,抗病性对感病性为显性;目前,梨树对梨黑星病的抗性机理尚不清楚;通过分子标记标记出的抗梨黑星病基因Vnk,和Vf一样均在第1连锁群;通过多种育种手段已培育出一些抗梨黑星病品种并在生产中得以推广应用。

摘  要:
The progress on the pathogen of pear scab (Venturia nashicola), the conditions of disease occurring, the mechanism of host resistance, and the inheritance of host resistance were summarized in the paper. There are two kinds of pathogens of pear scab, Venturia nashicola Tanak et Yamamota affects Japanese pears, however, Venturia pirina Aderh affects European pears. The resistance to pear scab was dominance to susceptibility. At present, the mechanism of host resistance was not very clear. The resistance gene Vnk is marked by molecular markers, it is in the LG 1 just like the apple scab resistance Vf. Some resistance pear varieties bred by multiple breeding methods are spreading for the commercial production.
