[Objective ]The objective of the current study was to determine alternative advantage of big-leaf Chrysan- themum nanklngense Guite No. 1 in wild vegetable production so as to update and screen wild Chrysanthemum nankingense varieties suitable for planting in Nanning and the surrounding areas of Guangxi. [Method]Morphological characters, yield traits of big-leaf Chrysanthemum nankingense Guite No.1 and common wild Chrysanthemum nankingense variety were compared. [ Result ]The average weight of young stem per branch and annual yields per hectare of Guite No. 1 were 4.48 g and 64245.5 kg,respectively, which were 1.20 g and 89.3%, respectively, extremely significantly higher than those of the control. The content of protein, vitamin and total flavonoids in Guite No.1 were higher than those in the control. However, cellulose content in Guite No.1 was 2.31% lower than that in the control. [Conclusion]Due to its high yield, long harvest- time and good quality, big-leaf Chrysanthemum nankingense Guite No.1 should be extended as a new health-care veg- etable variety.
