A new season is already started and this year I would like to try some of the old varieties. Does anyone have experience in breeding with the following roses as seed parent ?
Mmme Isaac Pereire
Paul Neyron
Peace
These seem to be healthy plants and I wonder if they would give some advantage for the seedlings.
Hello roseral, unfortunately, I canât tell you anything about the roses you desired. But I have found a thread about âPeaceâ here in the forum, pls see attached link below. Perhaps you will find some useful information here.
Otherwise, I would like to recommend the platform HelpMeFind. There you can check whether there are already descendants of your preferred rose and how the inheritance may turn out. This often gives a very good orientation, depending on the paternal parent of course. A Premium Membership even shows you the family tree, if the parents were specified, which is also very informative and helpful for all of us. Enjoy looking through!
Iâve tried several times, for amusement, to cross PN with both Maman Cochet and Marie van Houtte (object: 1st gen HT) with no success. Maybe 20% hip-set, and no germinations.
Hello Lee_hull,
Thank you for sharing your experience with PN. Much appreciated. This is exactly why I posted my doubts. I know that some roses are not fertile. Sometimes the hip falls down by itself, and some even develop hips, but never germinate. I will discard the idea of crossbreeding PN as mother plant.
Again, thank you very much.
Thank you for the link and for suggesting HMF.
I am a premium member of HMF and I will definitely go through the pages and try to find some more information there and while doing it, learn some more on how to navigate on HMF.
Best regards
I donât know that I would give up so easily. Paul Neyron has lots of descendants, and even the esteemed Ralph Moore used it as a pollen parent in at least one instance (0-89-07).
Thank you. I did not use it as mother plant, but I have used the pollen from Paul Neyron on my other roses including Mme Isaac Pereire and I am excited to see what it will bring. What I already can see is that the pollen probably taken by the mather plants, due to strong red coloring of the border of the calix and sepals. Now it is a matter of time.
Anything come of this cross?
Iâm curious where you are - when it comes to rose health, a lot depends on where you are located (and the growing conditions in your region). Here in the PNW, the three varieties you asked about are three of the least healthy roses I have ever grown, all extremely prone to Blackspot. I would not recommend any of that three for breeding, if disease resistance is your goal. Of course, if you live in a hot, dry climate, that may not be a concern for you.
âPaul Neyronâ is only going to be âusefulâ as a pollen parent (caveat about disease already mentioned) and it has certainly sired a few other roses. I have grown four of the Moore roses bred from âPaul Neyronâ, including the red climber 0-89-07 (which I still have). The three named varieties all suffered badly from Blackspot and had very poor vigor. All died from disease pressure within three years of my ceasing fungicide application (in 2010). I also grew âSchoenerâs Nutkanaâ for about ten years, but it also suffered badly from disease and declined and eventually died when I stopped using fungicide.
âMme. Isaac Perriereâ was just as bad in my climate. I see there is one hybrid made with it, listed on HMF that used Knockout as a parent, and I think that youâd have to follow a similar path with roses like âMme. Isaacâ to get acceptable results from it.
Breaking down the disease problem is a huge challenge in the Rosa genus. Iâve done may share of breeding involving âiffyâ parents that contributed nothing to the disease resistance effort and regretted some of those choices. If I were to start all over again, I would spend the first 5 years doing nothing but creating a group of disease free roses with good architecture and ignoring bloom traits entirely (well, perhaps not entirely). Then youâd have a foundation to build on.
Thank you for sharing you experiences, Paul!
All the challenges with black spot and other problems with roses as mostly seedlings are genetically sick due to interbreeding. I have got many seeds from my Mme. Isaac Pereira and I am waiting for them to sprout this spring. I am in Scandinavia, meaning that some roses will do well, and many wonât. It is very wet. All my roses in the garden are placed so that they received the most amount of sunlight, because shadows here creates a perfect environment for rose disease.
I will give you an update later this year when my MIP seedlings sprout.
I grabbed âSunspriteâ (in a âbody-bagâ, letâs hope it is correctly labelled; Iâll recognize the foliage immediately) for sentimental reasons today. It has always done well for me here on Vancouver Island, so I figure Iâll play around with it a lil bit, with some newer mates, older hardy mates, and see if it has anything left to offer.
I think youâll be pleased. Sheâs a very fertile mother; my âgo-toâ last year when thinking Pernetiana colors.
