This study was considered the differences among species and cultivars on pollen morphological characters of walnuts (Jugalns spp.) by scanning electron microscope (SEM). It was different only with the pollen size of walnuts among species and cultivars, and the pollens of walnuts were similar in terms of their pollen structure. For polar axis length (PL), ‘W33’, Japan cultivar having 46.05μm was the highest, whereas ‘Yangpyeong 2’, Korea selective cultivar having 27.18μm was the lowest. For equatorial diameter (ED) ‘Yongdong’, Korea cultivar having 46.05μm was the highest in this study, whereas ‘Yangpyeong 2’, Korea selective cultivar having 25.41μm was the lowest. For the number of pores (NP), ‘Nr. 139’, Germany cultivar having 18.40 was the highest, whereas ‘Muju 10’, Korea selective cultivar, having 12.20 was the lowest. In conclusion, the information obtained from this work was that pollen grains of walnuts were mixed subprolate and prolate in equatorial view; showed more or less periporate than 15 pores in aperture type; were largely divided into two groups (J. regia and J. sinensis) and a outgroup (J. mandshurica and J. sieboldiana); were mainly PL and PL and ED ratio in morphological characters of principle component.
