Implications of genetic variation within pyrethrum (Chrysanthemum cinerariifolium and Chrysanthemum coccineum) germplasm: Intra‐ or inter‐specific hybridization as mechanisms to circumvent genetic bottlenecks

Crop Science, Volume 65, Issue 3, May/June 2025.
Abstract The University of Minnesota (UMN) Pyrethrum Breeding Program has been developing Chrysanthemum cinerariifolium with increased levels of Pyrethrin I/Pyrethrin II ratio (%Py) for over a decade. Pyrethrum is an economically important “green pesticide,” producing %Py in glandular trichomes, with the highest concentration in the flowers.
