马铃薯对马铃薯包囊线虫（PCN）的广谱抗性。苍白质通常被认为是一种多基因遗传性状。然而，通过QTL分析和一组选定的PCN群体，对这两种PCN的抗性可归因于locusGrp1的作用。grp1对g有很大的抵抗力。rostchiensisline Ro5-22和g。白斑蝶种群Pa2-D383与部分抗g。pallidapopulation Pa3-Rookmaker。利用先前鉴定的AFLP标记将grp1定位在5号染色体上。可用于RFLP位点GP21和GP179的裂解扩增多态性序列（CAPS）标记显示，grp1位于包含其他病毒、真菌和线虫病原体抗性因子的基因组区域。目前的数据表明，grp1是一个包含多个基因参与PCN抗性的复合位点。
Broad-spectrum resistance in potato to the potato cyst nematode (PCN) speciesGlobodera rostochiensisandG. pallidais commonly regarded as a polygenically inherited trait. Yet, by use of QTL analysis and a selected set of PCN populations, resistance to both PCN species could be ascribed to the action of locusGrp1.Grp1confers major resistance toG. rostochiensisline Ro5-22 andG. pallidapopulation Pa2-D383 and partial resistance toG. pallidapopulation Pa3-Rookmaker.Grp1was mapped on chromosome 5 using previously characterized AFLP markers. Cleaved amplified polymorphic sequence (CAPS) markers available for RFLP loci GP21 and GP179 revealed thatGrp1maps on a genomic region harboring other resistance factors to viral, fungal and nematodal pathogens. The present data indicate thatGrp1is a compound locus which contains multiple genes involved in PCN resistance.
