In order to discover aphid-resistant germplasm,32 cut chrysanthemum (Chrysanthemum grandiflorum) cultivars were artificially inoculated with aphids,and the aphid number and its ratio on the cultivars were investigated.Different chrysanthemum cultivars had different levels of aphid-resistance.After 21 days inoculation,the aphid number varied with cultivars,ranging from 0 to 267.The aphid-resistance of chrysanthemum could be divided into five grades in terms of aphid number ratio,i.e.,high resistance (aphid number ratio 0-0.25),moderate resistance (0.26-0.50),resistance (0.51-0.75),low resistance (0.76-1.25),and non-resistance (1.25).Among 32 test cultivars,14 cultivars were of non-resistance,4 cultivars were of low resistance,3 cultivars were of resistance,1 cultivar was of moderate resistance,and 10 cultivars were of high resistance.read more

Inheritance and molecular markers for aphid (Macrosiphoniella sanbourni) resistance in chrysanthemum (Chrysanthemum morifolium Ramat.)
TL;DR: The inheritance model and molecular markers identified for aphid resistance facilitate the ongoing breeding activities in chrysanthemum, and are crucial to breed new chrysantshemums with strong aphid Resistance.

Identification of aphid resistance in eleven species from Dendranthema and Artemisia at seedling stage
TL;DR: The results showed that the aphid-resistance reduced with average damage index of aphid(I*) value increased under the field condition, and there is a growing need to screen Aphid-resistant germplasm from Dendranthema and its closely related genera Artemisia L. for the breeding of chrysanthemum.
