C.一年生PM 217对M. arenaria，M. incognita，M. javanica和M. sp.（塞维利亚型）。PM 687对前3种菌均表现抗性。与这两个品系杂交的寄主品种Yolo Wonder对M. javanica。通过雄核发育从F1杂种PM 217 ×获得单倍体植物Yolo Wonder和PM 687.尤洛·旺德每个同源二倍体后代分别接种4个种的5个根结线虫无性系群体。两个不同且可能独立的基因，一个控制对M. arenaria，M. incognita，M. javanica，另一个为M. javanica和M. sp. Seville，在PM 217中得到了证实。在PM 687中还观察到两个基因，其中一个对3种主要物种有活性，除了一个M。arenaria种群，第二个控制这个种群。这两个基因可能是相互关联的。这些基因的不同，其有效性的范围方面的根结线虫物种和克隆和/或其在根中的表达。来自PM 217和PM 687的广谱基因不是等位基因，但似乎位于同一染色体上。在Yolo Wonder中观察到第5个基因，但活性范围非常有限。
C. annuum PM 217 was resistant to M. arenaria, M. incognita, M. javanica and M. sp. (Seville type). Line PM 687 was resistant to the first 3 spp. The host cultivar Yolo Wonder, which was crossed with both lines, showed some resistance to M. javanica. Haploid plants were obtained by androgenesis from F1 hybrids PM 217 .times. Yolo Wonder and PM 687 .times. Yolo Wonder. Each autodiploid progeny was separately inoculated with 5 clonal populations of Meloidogyne belonging to the 4 species. Two different and probably independent genes, one controlling resistance to M. arenaria, M. incognita, M. javanica, the other to M. javanica and M. sp. Seville, were demonstrated in PM 217. Two genes were also observed in PM 687, one active against the 3 main species, except one M. arenaria population, the second controlling just this population. The 2 genes are probably linked. These genes differed by their range of effectiveness with regard to the Meloidogyne species and clones and/or by their expression in the roots. The broad spectrum genes from PM 217 and PM 687, respectively, were not alleles but seemed to be located on the same chromosome. A 5th gene was observed in Yolo Wonder but with a very limited range of activity.
