Nowadays, pollination management problem has been over comes through introducing new self-compatible for almond genotypes. Therefore, producing self-compatible genotypes has high priority in almond breeding programs. So, evaluation of self-compatible genotypes as compared to self-incompatible ones and study of their pollen effect is considered to be important. The present studies, effects of self and open pollination on some quantitative and qualitative traits in 13 self-compatible genotypes were studied. To do so, four branches with enough flowers were selected in each tree at balloon stage. They placed inside bags and selfing was carried out by hand. Two branches also were selected for open pollination in each tree to compare self and open pollination effect on fruit set as well as fruit and kernel characteristics. Results showed that selfing had no negative effect on any of fruit and kernel characteristics, but it significantly reduced fruit set percentage. To solve this problem, it is recommended to plant two highly self-compatible genotype together in the some orchard. However, some of highly self-compatible genotypes such as number 23 with high fruit set (18.23%) can the planted as a monoculture.
