Performance of 4 new and fresh pineapple varieties intercropped with young rubber plantation in Yunnan Province

In order to solve the problem of single and degenerated pineapple variety, which could not meet the marketing requirements of consumers in Yunnan Province, four new pineapple cultivars were introduced and intercroped with young rubber plantation. Intercropping experiment of four new pineapple cultivars, “Apple”, “No.8”, “Jinzuan”and “Tianmimi”, with young rubber plantation were carried out using random blocks design. Growth period was observed and fruit yield and quality were measured. The results showed that “Apple” had highest yield, “No.8”and “Tianmimi”had secondly higher yield, and “Jinzuan” had lowest yield.“Apple”and “Tianmimi”could be extended as mid-late maturity varieties of fresh pineapples, and “No.8”and “Jinzuan”could be extended as early-middle maturity varieties of fresh pineapples.
