Collected data were used to compare different effective population sizes based on phenological seed crop and paternity analysis. Our results did not show any difference of genetic diversity between parents and progenies. A limited pollen pollution was detected. We showed that distance and coflowering among clones had a significant effect on effective pollination and a significant effect of the production of flowers was revealed in one of the seed orchards. Our study also revealed a quite low number of effective size of fathers per mother but high effective sizes of mothers fathers and parents at the level of the seed orchard. Finally the calculation of effective size of mothers fathers and parents was not highly modified when having the .
