Abstract: In order to evaluate the resources of celery varieties, 29 celery varieties were selected and planted in Lishui District of Nanjing City in the autumn of 2018. Then, differences, correlations, principal components and cluster of 10 main agronomic traits were analyzed. The results showed that the variation coefficient of 10 main agronomic traits ranged from 9.11% to 39.74%. The highest coefficient of variation emerged in yield, which was 39.74%. There were different degrees of correlation among the agronomic traits. The yield exhibited a significant positive correlation with individual plant quality, plant height, petiole width and petiole thickness. Principal component analysis indicated that the cumulative contribution rate of eigenvalues of the first three factors reached 85.586%. These three factors, including plant type and yield factors, leaf and petiole number-related factors, as well as leaf and petiole morphology-related factors, summarized the information of original indicators in general. The 29 celery varieties were divided into 4 categories at the location of 10 Euclidean distances through cluster analysis. Among them, 16 varieties belonged to class I, their characteristic were as follow: plants were relatively short, quality of each plant was medium, leaves and leaf petiole color were different, and petiole was mostly solid. Two varieties belonged to class II, they showed a tall and strong type with heavy weight per plant, petiole solid, less fiber, high yield. The six varieties of celery belonged to class III, they were lower and stronger, and had the heavier weight per plant and round leaves, lower yield. Type IV contained five celery varieties, this type had short plants, many leaves, and low yield. The results of this paper would provide potential useful reference information for the production of celery in southern Jiangsu, and the collection and identification of celery germplasm resources.
