Abstract: Growth and survival of 33 populations from a species complex involving interior lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) and jack pine (Pinus banksiana Lamb.) and their natural hybrids in Alberta were evaluated at ages 5, 10, and 15 years in eight test sites across Alberta. We determined population differentiations by estimating Mahalanobis distances between populations from the canonical discriminant analysis of the total variability and by calculating dissimilarity indexes between populations from the quadratic regression of overall growth and survival on the overall climate. The grouping of the populations based on the Mahalanobis ...
