Cactus / Grafted seedlings 1

It is late autumn in here and the flowering of cacti has ended.
I grafted quite many seedlings last spring, around September to November last year.
They have grown nicely.
The photo is an Astrophytum hybrid, fukuryu banjyaky.
One of my friend gave me seeds and I propagated. I grafted 24 seedlings onto Perskiopsis.
They show various faces, from nudum to thick white flecking.
This one has thick white flecking.
