My GRIN orders generally support the columnar apple breeding effort in my Project W thread. No real results yet, just getting started. Anything that ends up being diseased I'll get rid of. My plan has been use these trees to pollinate my columnar apple trees to create specific crosses. But I have started to question whether I want to track all of that. I may go with open pollination, just grow out columnar seedlings, and see what I get.
I have also included some apple rootstocks that are only available from GRIN. Novole and Bud 490 I'll grow into trees and try to get hardwood cuttings to root to make my own rootstock. I got dwarfing rootstocks to compare interstems on B118 or MM111 but I decided that is too much work. I just kept the most dwarfing varieties to test 1 or 2 DR varieties. The rest were re-budded last summer.
I don't have anything on order now. I thought about Wellington Bloomless and Spencer Seedless. I have some pear rootstock on order and have been looking at late ripening pear varieties for a budwood order. My apple rootstocks will all be columnar bench grafts.
For 2015 budwood, I strictly I looked first for fireblight resistance, ripening times, and a variety of genetics (many crab hybrids). A couple I decided not to graft and a couple I lost the graft or the tree.
