Re: Rooting Cuttings from Seedlings

Peter,

Do you have a copy of your article?

I'm not entirely certain that my seedling was suffering from damping off, that was just my best guess.

Rooting Cuttings from Seedlings

Below is a description of my experience with rooting a cutting taken from a seedling that was 2 months old. It was originally written in 2016 as an article for the newsletter, hence its length. -Jonathan ------------------------------------------------------ On June 16, 2015, I made the cross ‘Climb...

Re: Rose Genome and the Possibility of (almost) Inseparable Traits

What you're referring to is called "linkage". The closer two genes are on a chromosome, the less likely it is that they will be separated by recombination. "Linkage Drag" occurs when a lot of unwanted genes are passed on to progeny due to their close proximity to a desirable gene.

Re: Easy Propagation

I tried a quick and dirty version (no cinnamon, no nail) that failed.

Even if it is successful though, I think you'd just end up with a potato plant growing up beside your rose cutting.

Re: Under-utilized species you feel might have merit

Phillip, I'm breeding specifically for the southeastern US, where blackspot is a huge problem. R. palustris , which will happily grow in standing water, is highly resistant to BS. Another thing I like about palustris are the long sepals and that the buds are covered in sticky glands that have a real...

Re: Under-utilized species you feel might have merit

I'm using R. palustris a good bit, but it can be quite stubborn. This cross was done in 2017 and is R. palustris x R. roxburghii normalis. The foliage is a nice intermediate between the two parents. It has a sibling from the same hip that doesn't look very much like a true hybrid, but that sibling d...

Mislabeled ID

This body-bagged 'Perfume Delight' *clearly* isn't 'Perfume Delight'. Any ideas as to what it could be?

Cream/seashell pink blooms. Slight spice fragrance.

Re: What about laevigata?

Here's an old thread about laevigata:

viewtopic.php?p=53441#p53441

I got around 40 seeds from 'Frau Dagmar Hastrup' x R. laevigata last season, but they haven't sprouted yet.
