I hav bred daylilies (hermocallis) for almost a decade now. I just started working with roses this yar more out of curiosity than anything. I do have a goal in mind. A rose that is drought tolerate mini and powdery mildew resistant. I choose Jeanne LaJoie because it performs well in my climate where other roses die off. I was just wondering what kind of children it produces.
Adam, welcome to rose breeding! With your daylilly experience, you will find rose breeding perhaps even more fun.
I only tried JL once several years ago and don’t remember getting anything worth keeping, however, others may have had more success with it.
In what area of the world/country to do live? Our main fungal pest here in Calfornia is powdery mildew. I have used ‘Baby Love’ with good success in ridding most of the seedlings of powdery mildew. You can then carry your best seedlings forward and get closer to your goals.
I am living in Fort Collins Colorado. Herepowdery mildew is more of a problem than anything else. I have seen some rust and absolutely no blackspot in the four years I have lived here. But powdery mildew and spider mites are two totally different problem. I like Jeanne LaJoie because it only shows a little powdery mildew at the end of the season. Same with Baby Love. I have crossed the two of them. I am planning to cross the two best seedlings I get from this cross. I believe in outcrossing, but I think one needs to inbread here and there to be sure of setting the characteristics you want. But as far as the climate. We sit in a bowl in the foothills that is hot and dry. Not so much a desert as say semi arid. We get hardly any snow coverage in winter except I guess every four years or so the wind is just right and it forces the clouds just right over the mountains. Almost no rain fall. Zone 6 I think.
Adam, your cross sounds like a good goal! I did a similar cross with further inbreeding using ‘Baby Love’ crossed with ‘Marmalade Skies’. The resulting seedling is a single, but it is completely clean in our climate and is very floriferous. It has been useful in other breeding. The cross that produced that seedling was (‘Marmalade Skies’ X ‘Baby Love’) X [(‘Marmalade Skies’ X ‘Baby Love’) X (‘Marmalade Skies’ X ‘Baby Love’)]. I have crossed it with shrubs, minis and HT’s and have been happy with several of the resulting seedlings.
