الملخص EN

The present research deals with the study of morphological characters of the fruits and seeds of the cultivars belonging to the species Morus alba L.

Namely (ʽBeautiful Dayʼ, ʽBig Whiteʼ, ʽReaseʼ, ʽGreeceʼ, ʽPearlʼ, ʽBorder Sweetʼ, ʽPendulaʼ); Morus latifolia Poir (ʽKokuse Koreanʼ); Morus rubra L.

(ʽAmarahʼ); Morus nigra L.

(ʽShamiʼ); Morus macroura Miq (ʽKing Whiteʼ); ʽDwarfʼ and Morus hybrid (ʽTiceʼ, ʽWellingtonʼ) Which cultirated in North of Iraq.

The study includes characters of the fruits (Shape, Color, Dimension, Size, Number of the fruitlet in the fruit) and the characters of the seeds (Shape, Color, Dimension, Number of the seeds in the fruit, and surface ornamentation).

The results showed some changes in morphological characteristics of the fruits and seeds examined by light microscope (L.

M), in addition to the surface ornamentation of the seeds examined by scanning electron microscope (SEM).

They also showed five types of the surface ornamentation (Reticulate, Muricate, Foreate undulate, Polygonal, and Ruminate) for cultivars species studied, showed that importance value in the separation between the cultivars of the species studied belonging to the genus Morus L.
