Abstract:
Knowledge of the self-compatible trait for commercial apricot cultivars and selections from breeding programmes is of great importance for apricot breeders and growers. A study on self-incompatibility of the main growing cultivars in Europe as well as selections from European and American breeding programmes has been carried out. Out of 123 cultivars tested, 72 were found to be self-compatible while 42 were self-incompatible. For nine cultivars results were not conclusive. Many of the self-incompatible cultivars were obtained from breeding programmes, which indicates that not enough attention has been paid to this undesirable characteristic during the selection processes.
