Re: first roses of the year

You might look at the pot plants at your supermarket or Big Box Store and look for varieties that have small foliage (so when normally grown it doesn't get large) and, of course, a beautiful flower with perhaps 20 to 30 petals, then peel away the petals of one flower that is almost open to see wheth...

Re: first roses of the year

I use small minis as males to get my progeny down to windowbox-size, my goal. So, I've crossed Oso Easy Italian Ice with an unnamed Por La Mar pot plant (grows to only a foot tall) that has 30+ velvety red petals of fine form. I care a lot about disease resistance but the rest of this rose's package...

Re: Is pollen's DNA the same on all flowers of a plant?

Very helpful. I will now, in taking pollen, take only from the best plant and, what the hell, the best individual flowers on the plant. Now seeing this year's seedlings bloom, I continue to be impressed with Oso Easy Italian Ice as a female. I'll be back-crossing onto it the pollen from the best see...

Re: Experience with prospective parents?

I've been using Oso Easy Italian Ice for two years now. It generously produces a decent percentage of doubles, disproportionately white/pink/yellow blends but some more saturated ones, of good form and health on a compact (1 to 2 foot) plant. I've crossed it with small minis (I mix the pollen), espe...

Re: Is pollen's DNA the same on all flowers of a plant?

I'm getting more variability. On one plant, the flower is bright yellow with red edges, on another, it's like the picture you send--various forms of pink and yellow blend. It is a wonderful rose in the garden--healthy, covered with well-formed 15-petal flowers of those beautiful colors you see in th...

Re: Is pollen's DNA the same on all flowers of a plant?

All are own root. And as I said, sun, soil, fertilizer, pots, are essentially identical.

Re: first roses of the year

Re microminis, I've now chosen to use them only as pollen in that Oso Easy Italian Ice is so good as a female. The micros I continue to use are the Por La Mar deep velvety red (unnamed) with 30+ petals and perfect HT form with small enough leaves that its true nature is micro-mini. My two plants of ...

Is pollen's DNA the same on all flowers of a plant?

Some flowers on a given plant have more or fewer petals and different coloration. The cause doesn't seem to be cultural--that is, different amounts of sun on that flower, nor different amounts of water on the petal, nor insect damage. Is the genome of two flowers on the same plant identical or would...

Re: Unique black spot resistance gene from 'George Vancouver' is better characterized

Is the cosmic scheme of things, the $10 is worth it triploid or not. What we need now, perhaps more than anything, is hope of a big win. It's a little like betting $2 on a relatively long-shot horse: a little thrill at the possibility of a big win, and if you lose, no biggie. At minimum, if you can ...

Re: Unique black spot resistance gene from 'George Vancouver' is better characterized

Is it possible that focusing TOO much on eliminating strains of BS, cerco, etc, we're ignoring a larger good? It appears it will take decades to make significant progress on this while at the same time creating a commercially wonderful plant? Are we not losing sight of Sam McGredy's urging that you ...

Re: The cross that's worked best for me

It seems more than worth it to have a rose that: a) sets some seed b) holds promise for building in additional BS resistance and most important c) Is an excellent rose in its own right: perfect non-fading yellow, 25 broad-enough petals, glossy, mildew-resistant foliage on a compact plant. Yes, it's ...

The cross that's worked best for me

This year, like last, my best cross is Oso Easy Italian Ice x mixed pollen (mainly elite red pot plants from Poulsen or Por La Mar and also Red Sunblaze as well as two of my best seedlings.) Of course, it's too early to say anything about the plants, but germination from this cross is around 35%, si...

Re: first roses of the year

And here it is in the ideal stage. Candidly, I'm shocked that the third to bloom seedling from my first breeding efforts in 20 years (and I had none so nice 20 years ago) is so pretty, so I thought I'd share these pix of it with you in hopes of inspiring you to perhaps try the cross: Oso Easy Italia...

tissue culture

When one has a seedling he'd like to have tested in multiple locations, does one make cuttings (e.g., 1-node, 3-node) or is tissue culture a viable option? If so, is there some lab that does that?

Re: first roses of the year

I do not believe that coloration was sun-induced: 1. It bloomed in early April--not much sun 2. The days during its bloom were not that sunny or hot. 3. Believe it or not, it's now been over a week and the color has remained stable and the flower still looks good---Alas, just 11 petals. We'll see if...

Re: first roses of the year

Indeed, it is the first bloom on any of my 300+ seedlings this year. I'm not sure the pollen parent is Gigi Parade. You see, I used mixed pollen---Red Sunblaze, an unnamed red pot plant, and Gigi. But with the coloration ofthe flower, I'm assuming it's Gigi. Of course, I could be wrong. Re phototrop...
