Hybrid Larch - Southern Pine of the North?

An international experiment was started in 1973, in the Great Lakes - St.Lawrence forest region, to assess the growth rate and form of larch hybrids from the best and most highly selected material available in northern Europe at this time. In Quebec, 20 seedlots (6 seed orchards, 14 half-sib progenies) were tested at eight locations with 13 seedlots of european larch and 10 of japanese larch as controls. The seedlings were planted in 1977 and 1978, at a spacing of 2.5 m x 2.5 m. Results from the three most comprehensive tests are presented to compare the growth of five hybrid seed orchard seedlots with that of the controls (five european and eight japanese).
