The authors explored the selection criteria, selected method of superior tree Sapium sebiferum Roxb., screened ten trees of elite plants on yield in on and off year with non-obvious difference, high ratio seed-bearing branch, big seed, oil-content rate above 42% and less pest and disease based on survey of such resource in the whole province through preliminary, repeated and final selection which set a good foundation for the stock breeding of Sapium sebiferum Roxb.
