摘　　要：目的:选育温郁金优良品种。方法:采用系统选择方法从"温郁金1号"变异植株中选育出优异新品种,测定其农艺生产性状和品质特征。结果:育成温郁金新品种"温郁金2号"[浙(非)审字2015002]。经小区品比、区域试验后最终审定成为新品种。两年区域试验结果为温郁金2号各项生产指标和品质指标均优于对照,莪术、姜黄和郁金药材干品平均产量分别达4387、2481、945 kg·hm^(-2),分别比对照增产12.03%、10.38%和21.29%;生育期220~233 d;株高192.5 cm;萌发数5.6个;莪术药材中挥发油含量5.5%(m L·g^(-1)),较对照高31.11%。结论:"温郁金2号"综合性状表现优异,特别是莪术挥发油含量高,适宜在主产区推广种植。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.
