In this research, during three consecutive years (2010-2012), a series of diallel crossing was performed among wild type barberry genotypes and Iranian seedless barberry. Setting of seed and fruit in the crossing have been studied and then seedling survival were evaluated in several cultural systems. Results showed significant effects of pollen sources on setting of fruits, seed and seeded fruits in seedless barberry. Pollens of R2N1 genotypes with 46% fruit set and 2.22% seedset and pollens of R4N1 genotype with 69% fruitset and 20.22% seed set had the lowest and highest rates, respectively. Also, There was significant differences (p<0.01) among genotypes on setting of fruit, seed and seeded fruit when pollinated with seedless barberry pollens. In this study, the efficiency of seedless barberry pollens to set seed in wild type barberries was proved and its male sterility theory was rejected. Evaluation of seedling survival rate showed that planting barberry seeds in spring in Cocopeat mixed with Perlite under mist system could increase dramatically seedling survival rate.
