Abstract: Field experiments were conducted in the high-yielding environment at Taoyuan to wnship Yu nnan, in 1995 and 1996. Yield and yield components were observated and the relat ionship between yield and yield components were investigated. The main results are as follows The highest yields were 15.27 t/hm2

Key words: Oryza sativa L., 15t/hm2 grain yield, Yield components, Yunnan
