Mint Varietal Improvement
Project Goals:..............Develop genomic and germplasm resources for the continued improvement of commercial mint cultivars
Mints (Mentha spp.) are important specialty crops, grown in temperate climates for distilled essential oils oils and as aromatic herbs. Commercial cultivars auch as peppermint and spearmint are clonally propagated polyploids, originating from a series of hybridizations, which presents difficulties for both breeding and genetic studies. We are performing crosses between ancestral mint accessions, attempting to generate breeding populations with restored fertility and desirable characteristics (oil composition and Verticillium wilt resistance). These efforts are informed by genotyping and chemotyping diverse mint accessions, genome sequencing, genome-wide association studies, structure-function studies to elucidate the physiology and biochemistry underlying essential oil biosynthesis and disease resistance.
