野生番茄对马铃薯囊线虫病的抗性已得到证实。pimpinellifolium、B6173和L.秘鲁线虫B6001对3个分离株的筛选试验结果表明，EsculentumAilsa克雷格作为对照。结果表明，这两个品种都对H的Wren分离株（致病型A）具有高水平的抗性。rostochiensis，以及对Castle多宁顿（致病型A、B和E）和Hare Lane（致病型B）分离株的抗性。L. pimpinellifolium比L.秘鲁。由于它具有更强的抗性，而且很容易与番茄品种杂交，L。为了将抗马铃薯胞囊线虫性引入番茄品种的育种计划，选择了pimpinellifolium作为供体亲本。pimpinellifolium，B6173与H. rostochiensis被证明是由一个单一的显性基因控制的符号Herois提出。
The presence of resistance to potato cyst-eelworm in wildLycopersiconspecies was confirmed.The resistance of two plant accessions,L. pimpinellifolium, B6173, andL. peruvianum, B6001, was compared in screening tests against three eelworm isolates, using the susceptibleL. esculentumAilsa Craig as a control. Both accessions were shown to possess high levels of resistance to the Wren isolate (pathotype A) ofH. rostochiensis, and resistance to the Castle Donington (pathotypes A, B, and E) and Hare Lane (pathotype B) isolates. The level of resistance inL. pimpinellifoliumwas greater than that inL. peruvianum. Because of its greater resistance, and the ease with which it can be hybridised with tomato cultivars,L. pimpinellifoliumwas chosen as a donor parent for breeding programmes designed to incorporate potato cyst-eelworm resistance into a commercial tomato variety.The resistance ofL. pimpinellifolium, B6173, to the Wren isolate ofH. rostochiensiswas shown to be controlled by a single dominant gene for which the symbolHerois proposed.
