Long-Term Field Evaluation of Conventional vs. Micropropagated Plants of Chrysanthemum cinerariifolium

Pyrethrum is a perennial herbaceous plant endemic to the eastern coast of Adriatic Sea, and introduced in large areas nearly all continents, where it cultivated for industrial extraction pyrethrins. Pyrethrins are group six closely related monoterpene esters, widely used as natural insecticides. The world production pyrethrins lower than market demand, wider introduction this crop within Mediterranean agrosystems could be an appealing opportunity farmers manufacturers. availability adequate amounts selected material bring into cultivation is, however, one major issues. Therefore, vitro propagation elite pyrethrum genotypes suitable alternative conventional methods. In paper, we present results 9-year field comparison between plants coming from protocol obtained by cutting same mother plants. Furthermore, since plantlets derived regeneration may experience ploidy changes, evaluated stability level pyrethrum-micropropagated flow cytometry (FCM) analysis. FCM screening revealed no differences among morphotypes them plant. Likewise, evaluation gave significant flower yields both groups. Hence, micropropagation was confirmed easy, efficient reproducible method obtain quantities genotypes.
