番茄青枯病是番茄的主要病害之一,严重威胁着番茄生产。目前尚未找到有效的药剂,因而抗病品种的选育和利用,是一项防治番茄青枯病的根本措施。近年来番茄品种的抗病性鉴定和抗病育种工作已普遍开展,并筛选出一批抗源和选育了一些较抗病的品种。同时还发现有的品种对不同菌株的致病反应有差异,这说明了菌株间具有不同的致病力。因此,摸清番茄青枯病菌(Pseudomonas solanacearum
Tomato bacterial wilt is one of the main diseases of tomato, which is a serious threat to tomato production. At present, no effective medicament has been found yet, so the breeding and utilization of resistant varieties is a fundamental measure to prevent and control tomato bacterial wilt. In recent years, the identification of tomato varieties and disease resistance breeding have been carried out universally, and a number of resistant and selected a number of resistant varieties. At the same time, it was also found that some varieties had different pathogenic responses to different strains, which indicated that the strains had different pathogenicity. Therefore, to find out the tomato bacterial wilt (Pseudomonas solanacearum
