Rose Hybridizers Association Forum

I live in East TN, and a barefoot of Mutabilis just arrived in the mail. Due to Park Seed's labeling, I thought that it would survive in my climate; however, it seems rather marginally hardy. Any advice on how to keep it alive in my garden?

If anyone has any unwanted seeds within the above criteria, I'm willing to pay for postage plus whatever you feel is appropriate. Unfortunately, most of the seedlings I grew were destroyed by fungal gnats; due to my inexperience, I didn't use a fungicide (which I have fortunately rectified with a ec...

Thanks for all the info. It seems that epigenetic play a larger role than previously thought!

Are there any species of roses that, while common, have never been experimented with greatly? I'm interested in diversifying the roses used in the garden. Particularly, I'd love to incorporate the blood of American roses (r. nitida, r. arkan. , r. vir. , r. car. , etc.). On a side note, do the other...

Would this (or how should this) translate into reproduction of our own seedlings that we wish to have more copies for testing or breeding with? Are there steps to take starting with the first plant and those thereafter that we can take to avoid this? Or is this usually amplified over time by many c...

I have obtained several rose books for a Christmas gift. One of them mentions the concept of 'replicative fading'. I am rather confused as to what this exactly entails. The book used 'Peace' as an example of a rose that has been regarded through reckless duplication via cutting. So, are the cuttings...

What roses would you all use for parents? I have heard that foetida is very sterile - are there other good options? I'm looking to cross a yellow species rose with some purple varieties to see what color combinations come out of the mingling.

To everyone who wrote back, thank you so much for the advice! I'm very excited to be getting started. I have one more question: I have a cutting that I was able to root (I don't know the variety). It is still very small - thus, should I put it outside in a pot, in the ground, or keep it inside under...

Hello all, I'm excited to be here. I've recently become interested in the genetic aspect of plants (due to the pandemic, I've taken up some new hobbies). As such, I'd like to try and breed some interesting hybrids. I particularly wanted advice on the following: 1) What cultivars should I experiment ...
