Forty years of tree improvement in New Zealand has provided a large data base of progeny test information. This paper discusses how this information has been used to guide the development of the radiata improvement program in New Zealand. In particular it has helped to answer questions regarding: The need to regionalize breeding in New Zealand; How many sites and where to place these sites for further progeny testing? What traits to measure and when for efficient generation turnover? In some parts of Canada there is an extensive enough data base to apply similar quantitative methodology. The New Zealand approach to multiple trait improvement is also discussed.
