Value gains from using genetically improved radiata pine

G.R. Johnson , A. Firth and P.C. Brown

Paired plots were established in a 17-year-old stand consisting of stock of two different levels of genetic improvement. The more improved stock had 11% greater live volume than the less improved stock. Results from computer simulation indicated that there was also a shift in log grade distribution, particularly in stems marked as thinnings. The improved stock had a higher percentage of sawlogs, resulting in increased value per hectare of the improved stand well in excess of the percent gain in live volume.
