Plants of two pentaploids (A and B) and one tetraploid (C) produced as a cross between diploids and octoploids in Fragaria. (A) F1 progeny of the ‘Hawaii-30’ and
‘Akihime’ combination. The left pictures on the bottom show sterile crosses (right) compared with fertile crosses (left), and right pictures show variation in leaflet morphology
of the F1 progeny (right) compared with the pollen donor (left) and seed parent (middle). (B) F1 progeny of the ‘Akihime’ and ‘Whiteberry’ combination. The pictures on the
bottom show leaf morphology of F1 progeny (left picture) and show variation in leaflet morphology (right picture) in the pollen donor (left), seed parent (middle) and F1
progeny (right). (C) F1 progeny of ‘UC-01’ × ‘Hawaii-30’. The pictures on the bottom show fruit shape (left pictures) and leaflet morphology (right picture) of the pollen donor
(left), seed parent (middle) and F1 progeny (right), respectively
