Using RAPD and ISSR Molecular Markers to Analyze the Genetic Diversity of Rose scented Pelargonium Populations

In the field, the chemical constituents of the essential oil of Pelargonium graveolens cutting (diploid) and polyploid seedlings are the same, but the principal components of geraniol, geranyl formate, and linalool in polyploid plants are remarkably higher than those of cutting seedlings. The contents of citronellol, citronellyl formate, and rose oxide are significantly lower in polyploid seedlings than in cutting seedlings. ISSR and RAPD...
