Dear Corona members,
May you please give me some ideas on, how can i create multiple leaves texture for a single tree, so that my trees become look more realistic.
I need something like attached reference image.
Thanks in advance.

That are two variantions going on. The one you're asking for is done with vertex color gradient. GrowFx can generate it, but manually it could be quite a labourous with the poly amount :- ). Don't overlay this layer on diffuse only (inner older leaves are darker, younger branches are brighter), but also on translucency parts (older leaves are thicker, less translucent).
The other one for nice touch is just done per leave by Multitexture/CoronaMultiMap.

vertex paint will work fine in this case

Hi Juraj. Thank you for your reply.
Actually sorry to say but i don't have any idea about vertex color. How can i use vertex color for making leaves realistically?
And if i do manually then how can we select a lot of leaves individually one by one?
Don't overlay this layer on diffuse only - which layer you are talking about?
Please can you explain full process.actually i am not so good in exterior vegetation renderings but now i am exploring myself. i will be very thankful to you.

A rough solution, since that trees are so far from the camera, is use a noise map as mask between some textures or materials.
If you have forest pack installed there, you could try to use forest map too.

ForestPack Color map is perfect 3rd step, to color each tree instance differently, but the OP wants just single tree gradient.
If you don't have GrowFx tree, you can still do this manually using traditional vertex painting, just prepare a lot of patience because of the polycount :- )
Here, Bertrand has done great tutorial imho:

or
~ just select leaves geometry (through mat id), detach and apply any random selector script
-
That does something different...
It's best to use all 3 ( leave randomization through ID, gradient for branches through Vertex, and instance randomization through color overlay ) method, but each does something completely else, they're not alternatives.
There is no need for random selector script when MaterialByID modifier does it.

i mean when you have one mat id for the leaves you can to do new several different mat id from 1 mat id (leaves) -> fast and easy
-
I made mistake, it's called MaterialByElement, and it does what the scripts do, you just don't have to use any script.
The modifier does create the IDs. It's even faster...
