Abstract

Sixteen Meloidogyne isolates from tomato fields in California grown with resistant cultivars were multiplied on resistant tomato in a greenhouse. Of these resistance-breaking isolates, one was identified as M. javanica, and all others as M. incognita. The reproduction of the M. javanica isolate and four M. incognita isolates on six resistant tomato cultivars and on susceptible and resistant cultivars of pepper, sweetpotato, green bean, cotton, and cowpea was evaluated and compared to an avirulent M. incognita population in greenhouse pot trials. On resistant tomato cultivars, there were minor but significant differences between the resistance-breaking Meloidogyne isolates and between the different tomato cultivars. Of the other resistant crop cultivars, pepper was resistant to all isolates and green bean to all M. incognita isolates, while cotton and cowpea allowed reproduction of one of the resistance-breaking M. incognita isolates. The resistant sweetpotato cv. Bonita behaved like resistant tomato, allowing reproduction of all five resistance-breaking isolates but not of the avirulent M. incognita. Our results showed that variability exists among resistance-breaking Meloidogyne isolates, and that isolates overcoming resistance in tomato may also be virulent on resistant sweetpotato.

番茄Mi基因抗根结线虫群体在感病和抗性作物上表现出可变繁殖。

来自加利福尼亚州番茄田的16个根结线虫分离株与抗性品种一起在温室中对抗性番茄进行繁殖。在这些破坏抗性的分离株中，一个被鉴定为爪哇M.javanica，所有其他分离株被鉴定为隐姓埋名M.incognita。在温室盆栽试验中，对爪哇M.javanica分离株和四个M.incognita分离株在六个抗性番茄品种以及辣椒、红薯、绿豆、棉花和豇豆的感病和抗性品种上的繁殖进行了评估，并与无毒的M.incognata群体进行了比较。在抗性番茄品种上，破坏抗性的根结线虫分离株之间以及不同番茄品种之间存在微小但显著的差异。在其他抗性作物品种中，辣椒对所有分离株都有抗性，青豆对所有隐姓埋名分枝杆菌分离株都具有抗性，而棉花和豇豆则允许其中一个抗性破坏的隐姓埋籍分枝杆菌分离物繁殖。具有抗性的甘薯品种Bonita表现得像具有抗性的番茄，可以繁殖所有五个抗药性分离株，但不能繁殖无毒的隐翅虫。我们的结果表明，抗药性的根结线虫分离株之间存在变异性，并且在番茄中克服抗性的分离株也可能对抗性甘薯具有毒力。
