| Abstract:
The architectural development of four apricot cultivars was described from the 1st to the 3rd years of growth in three contrasted climatic areas in France. Statistical analyses were carried out on main morphological and architectural traits in order to separate the respective effects of the environment and genotype and their possible interaction. A large part of the observed variability on shoot diameters and number of lateral branches was explained by the genotype. This suggests that the integration of these traits early in breeding scheme could be relevant. By contrast, the variables related to primary growth were mainly influenced by the environment. | |
