Abstract: In order to clarify the contribution rate of main agronomic traits of confection sunflower to yield in Guizhou and the relationship among these traits, 50 representative local confection sunflower germplasm resources in Guizhou were used as materials, the coefficient of variation, correlation, principal components and cluster analysis of main agronomic traits of confection sunflower were conducted. The results showed that there were abundant variations in the agronomic traits of sunflower resources, and the coefficient of variation was more than 10%, among which the coefficient of variation of percentage of empty shell of 100 grains, kernel weight per plate and grains per floral disc were large.It indicated that the possibility of improving utilization of confection sunflower resources in Guizhou was great. In the correlation analysis, the yield was significantly positively correlated with plant height, grains per floral disc, kernel weight per plate, and negatively correlated with percentage of empty shell of 100 grains. The results of principal component analysis showed that the main information of the 12 agronomic traits was concentrated in the first five principal components, and the cumulative contribution rate was 83.39%. Grains per floral disc, kernel weight per plate, percentage of empty shell of 100 grains, 100 grains weight, plant height and floral disc were the main influencing factors of sunflower germplasm resources. Cluster analysis divided 50 sunflower resources into four categories when the Euclidian distance was 11, among which the first category was the dominant type for confection sunflower planting.
