Chrysanthemum Frost Resistance

Chrysanthemum L.

Chrysanthemum frost resistance is a key component of its winter hardiness and is assessed by experts using scoring systems or the percentage of survival in open ground.

In the reference 21 varieties crop Chrysanthemum, where this is mentioned in the description.

For chrysanthemums, especially garden and Korean groups, frost resistance is evaluated primarily within the framework of complex winter hardiness. There are no specific temperature thresholds for plant mortality, so breeders use scoring scales to evaluate bush survival after winter and calculate the percentage of surviving individuals from the total number planted.

In breeding work, introgressive hybridization is used to increase frost resistance, employing high-altitude Manchurian and Korean species as donors of resistance polygenes. High values of this trait determine the possibility of growing a cultivar as a perennial without cover, while cultivars with low values require lifting for the winter or cultivation in an annual cycle.
