Early Results of an Ottawa Valley White Spruce Progeny Test Planted in Maine

One-hundred-nineteen families from 31 stands located in the Ottawa Valley were tested for superior height growth in nursery beds in Maine. After two growing seasons, survival was 88.2% with a range in stand survival of 76% to 100%. Stand and family height differences varied significantly accounting for 27% and 14% of the total variation respectively in 1979. Nine of the top ten stands were from the Beachburg, Ontario area and averaged 15% better than the study mean and 37% better than the local Maine sources.
