| Abstract: | Association analysis were undertaken to detect the genetic markers significantly related to the 6 ornamental traits（i.e. plant height，plant width，the ratio of plant height to plant width，internode length，leaf length and leaf width）in vegetative stage by the method of One-Way ANOVA based on a F1 population derived from chrysanthemum cultivars，‘Yuhualuoying’and ‘Aoyunhanxiao’. The result showed that the 6 traits segregated significantly in the F1 population（coefficient of variation > 20%），basically fitting in a normal distribution. The One-Way ANOVA analysis revealed that the number of genetic markers significantly associated with plant height，plant width，the ratio of plant height to plant width，internode length，leaf length and leaf width was 15，9，9，11，7 and 8，respectively. Of these genetic markers，the cumulative contribution ratio for each trait was above 30%，whereas the contribution ratio of each single genetic marker ranged from 2.77% to 8.50%，revealing that these markers were polygene with little effect. We anticipated that the proper utilization of these genetic markers significantly associated with these target traits would effectively improve selection breeding in chrysanthemum. |
