Diallel Cross in Pinus cembra: The Nursery Test at Age Six

A 10 x 10 full diallel cross was made in a native population of Pinus cembra L. from high elevation, to provide information about genetic variation and inheritance of important breeding traits, for the species. In October 1991, seeds were sown in individual polyethylene pots, in spruce humus. The families, including selfed and open pollinated parents, were arranged in a randomized complete block design with 4 replication and 12 seedlings per plot. Six traits were measured, prior to field planting, when the progenies were 6 years old: total height (H.6), height increment in the 6th year (h.6), diameter at root collar (DRC), number of buds around the leader bud (NBAL), total number of branches (TNB) and lamma shoots formation (LS). In addition, the weights of 100 seeds (100 SW) of each family were measured prior to sowing and cotyledon number (CN) was counted after seed germination.
