Evaluation of the feed value of Pterocypsela indica ‘Dianxi’

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.
