Abstract
The aim of this research is to determine the rate of pollen germination and pollen production of 29 hybrid walnut genotypes. For this aim, the germination percentage of the pollens was examined by using the agar in the petri and hanging drop methods. Pollen production amount of the genotypes was determined with the hemacytometric method. The highest germination ratio of genotype 30 was obtained by the agar in the petri method in 1% agar+10% sucrose (54.65%). In 15% sucrose concentration in the hanging drop method, which is the best medium for all 29 hybrid walnut genotypes, pollen germination rate was 51.84% (genotype 9). The amount of pollen in a flower and an anther is very high in all genotypes. The consequence indicates that different treatments had a significant effect on the germination percentage. As a result of the findings obtained from this study, genotypes can be used as a pollinator.
