So, this is my try:

File is here.
Notes (also included in the file):
– Icosphere as Instancer:
Duplication on instancer vertices
(https://docs.blender.org/manual/en/latest/scene_layout/object/properties/instancing/verts.html)
– edit the fruit “scales” only in
“Edit Mode”: the local Y axis is aligned with the vertex normals of the instancer
=> “Tracking Axis” set to “+Y” (default)
and “Up Axis” to “Z” (default)
in the “Relations” panel
of the “Properties Editor”
– grooves made with edge beveling and inset (using CTRL for creation of depth);
vertices connected with edges (using “J” key) in order to make it all quads
– “Simple Deform” modifier in “Bend” mode to curve the fruit “scales”
– UV-Sphere to fill the gaps between
the fruit “scales”
– both spheres slightly deformed; top and bottom vertex of the icosphere instancer dissovled
(by joining the surrounding faces) in order to avoid unwanted instancing of fruit “scales”
at these “sphere poles”.
– further tweaking needed after application of the modifiers and making the duplicates real
