Absolute resistance to potato virus Y pathotype 0 (PVY 0), potyvirus E and chili veinal mottle virus (CVMV) and a partial resistance to potato virus Y pathotype 1,2 (PVY 1,2) were found in an Indian pepper line, 'Perennial'. In the doubled haploid (DH) progeny from the F1 of a cross 'Perennial' by 'Yolo Wonder', resistance to CVMV was confered by two independent genes, one with a clear dominant effect. Resistance to PVY and potyvirus E was quantitatively expressed and controlled by several recessive genetic factors. Genetic analysis showed that fewer resistance factors were necessary to explain resistance to PVY (0) and potyvirus E than resistance to PVY(1,2). Genetic correlations between resistances to the different potyviruses in the DH progeny showed that most of genetic factors involved in PVY(0) resistance appear to be also involved in potyvirus E resistance, and some of these polyvalent factors may be also involved in PVY(1,2) resistance but, in this case, additional specific genes were necessary. One of the two CVMV resistance genes seems to be implicated in potyvirus E resistance. Thus, the polygenic resistance of 'Perennial' to these potyviruses was due both to polyvalent genetic factors, i.e. factors that apparently interact with several viruses, and strain-specific genetic factors.
在印度胡椒品种 'Perennial' 中发现了对马铃薯 Y 病毒 0 型（PVY 0）、马铃薯 Y 病毒和辣椒叶脉斑驳病毒（CVMV）的绝对抗性，以及对马铃薯 Y 病毒 1、2 型（PVY 1、2）的部分抗性。在 'Perennial' 与 'Yolo Wonder' 的杂交后代的双单倍体（DH）群体中，对 CVMV 的抗性由两个独立的基因决定，其中一个具有明显的显性效应。对 PVY 和马铃薯 Y 病毒的抗性是由几个隐性遗传因素定量表达和控制的。遗传分析表明，解释对 PVY（0）和马铃薯 Y 病毒 E 的抗性所需的抗性因素比解释对 PVY（1、2）的抗性所需的抗性因素要少。DH 后代中不同马铃薯 Y 病毒之间的抗性遗传相关性表明，参与 PVY（0）抗性的大多数遗传因素似乎也参与马铃薯 Y 病毒 E 的抗性，并且其中一些多价因素可能也参与 PVY（1、2）的抗性，但在这种情况下，还需要额外的特定基因。两个 CVMV 抗性基因之一似乎与马铃薯 Y 病毒 E 的抗性有关。因此，'Perennial' 对这些马铃薯 Y 病毒的多基因抗性既归因于多价遗传因素，即显然与几种病毒相互作用的因素，也归因于特定株系的遗传因素。
