An International Provenance Trial With Larix Leptolepis

In view of the present state of knowledge, the lay-out of a provenance trial cannot be only for the purpose of proving the existence of genetical differences among populations. These trials should be especially to find suitable provenances for special sites and to have a glimpse into the genetical composition of the different populations as well as into the manner in which the genotypes are allotted in the natural distribution area. Furthermore it should also be determined how the genetical variation of each single provenance changes under different environmental conditions. Such information is surely of the greatest value for breeding research as well as for practical forest-tree breeding.
