Thanks for the response Richard, but I searched that thread and while there was a bunch of discussions re grafting Nadia 5+ years ago there was very little in the way of long term results posted.
Common post 6 years ago:
6 years later, still not much in the way of conclusive answers:
I searched the entire thread with the terms “interstem” and “graft”. There were lots of hits on people stating they were going to attempt various grafting combinations, but little in the way of long term results posted.
I’m guessing this probably means Nadia isn’t particularly compatible with other varieties, as people are far more likely to post about their grafting successes, rather than their failures.
For sure, Nadia is compatible to plums, both Japanese and Euro. Originally, I grafted it to a Shiro, it grew well and was fruitful. I removed the tree so Nadia went with it.
I grafted Nadia to a Euro plum a year later. It has grown well and should have flowered this year had we not have a serious temp dip in Feb that killed all my J plums’ and Nadia’s flowers.
I have not tried grafting it to other stone fruit.
Has the autentisity of Nadia as a 50% prunus avium and 50% prunus salicina hybrid ever been confirmed by DNA testing ??? It strikes me that there is something wrong here …
I see a lot of P. salicina traits everywhere on the photos, but not a single P. avium trait thay would blow away any doubt. Not in the leaves, not in the buds not in the flowers not in the fruit. What is your opinion ?
Here’s info from the patent
“The inventor hand pollinated a limb of a ‘Black Amber’ plum tree located in his commercial orchard at Shepparton, Victoria, New South Wales, Australia, with pollen from ‘Supreme’ cherry. After pollination, the limb was bagged to prevent further pollination. Two hundred seeds were collected from fruit set on the selected branch, and planted in pots for observation. Of the two hundred seeds planted, only 5 produced seedlings. The five seedlings were grown on until large enough to harvest budwood for further propagations. The budwood was topworked by grafting onto 20 plum rootstock trees for evaluation. It was from these topworked trees that ‘Nadia’ was selected.”
I guess it’s possible that those viable seeds were actually pollinated by a plum prior to hand pollination, how does it compare to other hybrids? Do they often have clear avium traits?
Many of these plum interspecific hybrids inherit most of the plum traits. For example, a couple of years ago, a member from Dave Wilson Nursery forums created a peach x plum hybrid. The fruit had a smooth skin, a very small pit, and the flesh was similar to that of Santa Rosa. The only trait that it distinguished it from a stardard plum was it’s peach-like leaves.
