Yellow seedling

I’ve been jealous of everybody’s seedling pics and finally mine are starting to open. I really like the color on this golden yellow seedling.

The pink one behind it has a nice fruity fragrance.

Updates and random show and tell:

Here's that yellow one after it opened. The petals fell after a day so it didn't have much of a chance to fade:

It looks like there are more than the one yellow seedling and a bit of red on the reverse of one. Are these all from the same cross?
What doesn't kill them makes them stronger.

How long does it take to get from seed to a small plant with flowers like that?

Did it flower in its first summer?

Julie,

These are seedlings that germinated and were planted in March or April of this year....I can't remember exactly when they were planted.

One important principle in rose breeding is that if a rose will be a repeat bloomer it generally blooms like this at a very young age, in it's first summer. Roses that are destined to be one-time bloomers generally don't bloom in their first season. I make a lot of crosses that don't generate 100% repeat bloomers, so I use this quality to cull out any seedlings of those crosses that don't bloom the first season.

That is useful to know, thanks. I was thinking how incredibly patient you have to be to create a seed, grow it, and then wait. I have a few tiny seedlings from open pollinated roses, sown last October and germinated about March this year. They aren't as far on as yours, but they have been growing outside and we have only recently had proper summer days. I am hoping they will survive, and it would be wonderful if they flower this summer.

Don,

I've got a lot of yellow seedlings this season! All the seedlings in this pic have 1048 as a seed parent. The single yellow is x Lemon Fizz and the pink ones in back are x Fruity Petals.

I'm excited about the potential of 1048 as a seed parent. It gives a lot of warm colors and good color saturation. It's parentage is a bit of a mystery.
The listed cross was YWP x a pollen blend of Pink Double Knock Out and Hazeldean.

YWP, which stands for "Yellow Winnipeg Parks" is a seedling that I assumed to be an OP Winnipeg Parks, although it could have potentially been a cross. It's been years since I had that rose. It is up on HMF. It was a light yellow with nice double blossom form but just as disease prone as Winnipeg Parks. And I don't think it was particularily hardy...about the same as Winnipeg Parks, which dies back quite a bit. I remember I dug it up and kept in in a pot before eventually discarding it.

So how the heck did 1048 end up being a hardy, healthy, shrubby, plant that reblooms with orangey blossoms reminiscent of Morden Sunrise? I'm wondering if Hazeldean might have somehow contributed a single set of genes and allowed for rebloom. It makes me want to try Hazeldean pollen again.
