Objective： To breed an elite cultivar of Curcuma wenyujin with high production. Methods： System breeding method was adopted for the breeding of new cultivar from variable plant of ＂Wenyujin No. 1 ＂ . Meanwhile, the agronomy production traits and quality characteristics of ＂ Wenyujin No. 2＂ and local varieties were detected. Results： A representative new cultivar ＂Wenyujin No. 2＂ had been bred successfully. Then, the cultivar of ＂ Wenyujin No. 2＂ was examined and approved, after the district comparison and different large region experiments. After 2 years large region experiments, it has showed that ＂Wenyujin No. 2＂ was better than ＂Wenyujin No. 1＂ in both agronomy production traits and quality characteristics. The yield of zedoary, turmeric and eurcuma was reached 4387, 2481, 945 kg·hm^-2, respectively. It increased 12. 03% , 10. 38% and 21.29%, respectively, comparing with ＂Wenyujin No. 1＂ . The growth period was 241 to 250 d. The height of plant was 192. 5 cm, and the tiller number of plant was 5.6. The volatile oil contents in zedoary was 5. 5%, respectively, it increased 31.11% comparing with ＂Wenyujin No. 1 ＂ . Condusiort： ＂Wenyujin No. 2＂ has more excellent comprehensive performance comparing with ＂Wenyujin No. 1＂ . Especially, the volatile oil content in zedoary is much laigher than ＂Wenyujin No. 1 ＂, which is suitable for popularization at major production regions.
