“…All Mammothä garden chrysanthemums are notably winter-hardy herbaceous perennials that are butterfly attractants and frosttolerant. Mammothä cultivars have standard plant dimensions in the first year (Anderson et al, 2001) but achieve shrub status in Year 2 (Anderson et al, 2004(Anderson et al, , 2008. The Mammothä series is a collection of low-maintenance perennials resulting from their genetic ''selfpinching,'' removing the necessity to hand or mechanically pinch terminal shoots in midsummer to form the cushion habit (Anderson et al, 2008).…”

“…Cushion habit now predominates throughout the global market (Anderson, 2006). The chrysanthemum breeding program at the University of Minnesota is the oldest public sector chrysanthemum breeding program in the world (1926 to the present) and the only public sector chrysanthemum breeding program in the United States (Anderson et al, 2001). Trendsetting breeding endeavors, coupled with its germplasm base and genetic resources, continue to bring a wide range of colors and plant habits in hardy chrysanthemums for northern gardens.…”

“…While previous pyrethrum research has not reported the number of nodes or leaves on the primary stems and leaf unfolding rates, they have been reported in C. xgrandiflorum and C. xhybridum (Anderson and Ascher, 2001;Anderson et al, 2001a). Further studies would be required to determine if leaf numbers of pyrethrum under non-inductive photoperiods (short days) would be indicative of VBD since a similar trait (long day leaf number in non-inductive conditions) is used to program flowering of quantitative short-day chrysanthemums (Anderson and Ascher, 2001;Anderson et al, 2001b;Anderson, 2006).…”

Rapid generation cycling transforms pyrethrum (Chrysanthemum cinerariifolium) into an annualized perennial

2021

Pyrethrum [Chrysanthemum cinerariifolium (Trevir.) Vis.] is an important "green pesticide" crop widely used for insect control on plants and for humans. Pyrethrum flowers have the highest Pyrethrin I/Pyrethrin II ratio (%Py) and are harvested at specific stages to maximize yield. Selection for correlative early seed germination and flowering in first year pyrethrum seedlings is challenging and has not been accomplished previously. The breeding objectives for this study were to sample a wide germplasm base to select for rapid generation cycling (RGC) traits of early and high germination in Weeks 1-4, earliness of visible bud date (VBD) and flowering, accelerated growth, high leaf unfolding rates per week, number of shoots, and %Py in the 1st-12th flowers. Seven seed lots were evaluated for germination rate and timing (N = 141,120 seeds) in Year 1 for RGC traits. Seedling germination was recorded weekly with toothpicking to identify germination weeks with successive selection occurring at transplanting. Grand mean percentage germination was low (24.5%), whereas individual seed lots varied (18.4-38.9%). Seedling death was 0.0-6.8%. On average, it took 34-39 wk to reach VBD and an additional 3-4 wk to flower. Thus, flowering in <1 yr without vernalization is a new trait (annualized perennial) selected in this crop. Germination week was significantly correlated with VBD and flowering dates and is an important trait to use for selecting early-flowering genotypes in plug trays. Pyrethrum breeding programs could select the earliest germinating seedlings (Weeks 1-4 after sowing) at transplanting to enhance the likelihood of selecting early-flowering genotypes in the first year and provide an additional year of harvest to increase yield.
