Landrace material from New Zealand did not perform well compared to Australian and South African populations, suggesting early introductions to New Zealand originated from poor seed sources and/or suffered from inbreeding. Analysis of these trials has provided base genetic parameters for this species providing direction for the next generation of the breeding programme. Predicted genetic gains of 15% for tree form and diameter for the 1979 series, and gains of 8% for diameter and 12% for malformation for the 1994 series, indicate the potential for increases in both tree form and growth rate.
