摘　　要：为丰富我国的优良草种质资源和积极开发优良乡土草种质,本研究对云南德宏傣族景颇族自治州乡土种质滇西翅果菊(Pterocypsela indica ‘Dianxi’)开展了农艺性状观测和饲用潜力评价研究。结果得出,滇西翅果菊在云南热区具有很好的适应性,全生育期202～206 d,种子结实性能好,平均种子产量为94.75 kg·hm–2;其连续两个生产周期内的饲草产量显著高于对照品种蒙早苦荬菜(Lactuca indica ‘Mengzao’),其年均干草产量是蒙早苦荬菜的3.56倍,一个生产周期内可5次刈割利用,且再生性和饲草均衡供应性均较好。表明滇西翅果菊在云南热区乃至南方热区草地建植和草地改良中具有较大的开发利用前景。In order to enrich and exploit forage germplasm in China, we examined the agronomic traits and forage potential of Pterocypsela indica ‘Dianxi’ in Dai-Jingpo Autonomous Prefecture of Dehong in Yunnan. Results showed that ‘Dianxi’ has good adaptability in the tropical area of Yunnan. The growing period of ‘Dianxi ’ lasted from 202 to 206 days. In addition, this species has good seeding performance, with a higher seed yield of 94.75 kg·ha–1. The average forage yields of ‘Dianxi’ in two growing seasons were 2.56 times more than ‘Mengzao’. The regeneration and forage-balanced supply of ‘Dianxi’ were better than those of ‘Mengzao’, and it can be cut five times per year. In conclusion, P. indica ‘Dianxi’ has greater potential on grassland establishment and pasture restoration in the tropical area in Yunnan and southern China.
