Early Selection of Larix principis-rupprechtii

Abstract:

The growth process of tree height and basal diameter of 24-year old of 416 felled individual plants were measured to detect correlation between the early and late growth of Larix principis-rupprechtii. Rank correlation, phenotypic and genetic correlation between height, basal diameter and the tree-age were analyzed. Results showed that height of Larix principis-rupprechtii in early tree-age was closely correlated with that in late tree-age. It was feasible for early prediction and selection. It could select preferred in 2-year old nursery seedlings, and the second suitable selection period was at the age of 9-13. And tree height was a good indicator for early selection.
