Re: Grid for pollen measurement

Thanks Joe for the suggestion for this pocket microscope. Got mine in the mail today. Really neat. Here’s some just picked Snow Pavement diploid pollen. Getting the cellphone to take a decent photo was a challenge. It’s more clear/focused to the eye.

Re: Wasagaming and Snow Pavement as seed parents

self incompatibility is a continuum in terms of degree of expression and recognizing the factors that impact expression. In roses, the pollen from "incompatible" pollen germinates, but then grows much more slowly down the style and often gets stuck due to protein interactions/recognition. When ther...

Re: Wasagaming and Snow Pavement as seed parents

Thank you Johannes. I'm still trying to figure out how to do things. And often get confused about many terms used & need to use a search engine to understand. Donald, interesting cross, it would be interesting to hear how the seedlings turn out for you. It's good to hear Wasagaming will even accept ...

Wasagaming and Snow Pavement as seed parents

Update on some crosses I made in 2017. These were planted in the ground in July 2018 last year & all had developed powdery mildew in the fall. They were heavily mulched with straw, temperatures dipping down to the -30s C during February. I am curious if they will get powdery mildew again this fall, ...

Re: Kind of starting new

Joe, have you worked with Doorenbos Selection? It sounds like it might meet some of your criteria, except for shrubbiness and bloom form. I’m thinking of adding it one day, the comments about it on this forum sound promising.

Re: Is sterility sometimes a physical problem, and not genetic?

We’ve grown giant pumpkins in the past where adequate calcium & sufficient plant size was crucial to have fruit set.

I’ve also observed the same with bees preferring the flowers which are easier to access.

Re: Is sterility sometimes a physical problem, and not genetic?

I observed the opposite with 'Wasagaming', the stigmas did not appear ready until the flower started to fade & when they did look right, the window was short. Length of the stigmas were also short/held close to the flower. Repeated pollinations over several days seemed to help, as well as finding po...

Re: Wild Edric

Mntlover - Wasagaming is fertile for me as a seed parent, although picky. Example - one year out of 77 crosses, 37 formed hips. Some crosses took sporadically (Therese Bugnet, Marie Bugnet), however spinosissima pollen was usually 100% successful (Prairie Peace, Suzanne). It does not repeat, but put...

Re: Beginner Question, How to Streamline Germination & Planting?

Update, after about 5 months of stratification, I finally sowed the seeds about two weeks ago. Good thing I checked as some were sprouting in the peat baggies. I decided to spread the seeds out into 4' pots filled with a mix of 2/3 Pro-Mix BX and 1/3 coarse sand. The peat worked well as it was easy ...

Beginner Question, How to Streamline Germination & Planting?

Due to some health problems, I am far behind on stratification. I kept hips in the fridge, and finally had time/energy to remove the seeds from hips at the end of December. These were mostly rugosa/Arkansana/Spinosissima crosses, seed parents being 'Snow Pavement', 'Wasagaming', 'Winnipeg Parks' and...

Re: What causes this

I second wet soil media. I had something similar happen to a rugosa 'Snow Pavement' potted in peat-based Pro-Mix HP, photos attached. Damage in leaves was very sudden & upon removing from the pot I noticed the mix was wet and compressed at the bottom and some roots had died. Issue was solved once wa...

Re: Embryo Extraction from Spinosissima(?) Scotch Rose Seed

Thank you jbergeson! To add, I forgot to rinse out the little bowls I was using for the peroxide solution, next time I will rinse them out first, they were previously washed in the dishwasher and probably had some residual soap on them. Also, this time I kept the solution very cold by keeping the bo...

Re: Embryo Extraction from Spinosissima(?) Scotch Rose Seed

My previous attempts failed, so I decided to try again. I'm pleased as roots are starting this time. They are under lights 24/7. It's getting better with practice, I am only crushing about 1 out of 10 embryos now, where before it was almost all of them! Instead of starting with clippers I am using n...

Re: The Future Development of Canadian Roses

I have given up on tetraploid roses and work exclusively with diploids. I have gone on were Dr, Svejda left off. With here rugosas. I am breeding for near 100% hardyness above the snowline, red stemmed and smother leaves- rather like a Therese Bugnet plant. The flowers I want to be like a grandiflo...

To prevent the rain from washing away the pollen, I am giving this a try, garbage bags and tarps. It doesn't look pretty but it works most of the time.
