The sporophytic self-incompatibility mating system is conserved in Olea europaea subsp. cuspidata and O. e. europaea

摘要: Fruit setting after self-pollination, crosses and free-pollination appears to be erratic in the cultivated olive tree [Olea europaea subsp L. (O. e. L.)] because of a lack suitable model enable prediction rates. The same also applies wild taxon Olea cuspidata cuspidata). Because their close phylogenetic relationships, we hypothesize that O. share self-incompatibility system. We used data recently published wide study involving four accessions cultivars. varieties have been deciphered for S-allele pair, infer determinants present stigma pistil, coat pollen, S-alleles carried by three accessions. Data are too scarce number small speculate on genetic population structure. working hypothesis is confirmed. This from Italian team will us embark large-scale hybridization program between two subsp. obtain range progenies screening responses cold, diseases pests.
