I have Chinatown. It hasn’t been an easy one for me to catch for some reason.
‘Pot-o-Gold’ looks good but not available in the U.S.?
‘Singin in the Rain’ keeps coming back into the conversation doesn’t it?
It isnt on HMF but I know Heirloom has it. Whether or not theyre selling it is a different question. Theyre very disorganized about their products imo.
Singing in the Rain is okay. What I dont like about it is the tendency to produce blackspot prone seedlings. This is common of roses bred from the Sexy Rexy lineage and grown here.
I can look at Yellow Submarine at a small, local park this week if you want me to check for any issues on it. They planted two cause they got donations from Bailey’s.
btw I still think you should check out St. Christopher. It is light on petals but has been healthy for me. It is kind of intermediate between an HT and an FL. It is still young but it seems that it will mature to about 3-4’ and be very bushy/well-branched. The color is deep yellow with a gold/caramel reverse. The form is nice in the spring. It is rather light in petal count in the summer but I can forgive that since most yellows plain and simply suck.
I wish I knew the lineage of ‘St. Christopher’. I like to know what I’m working with.
To someone just starting out, I suggest crossing yellows from different hybridizers (spheres of influence). For example I would recommend crossing a Buck yellow with a Kordes yellow or an Austin yellow instead of crossing the Buck yellow with a different Buck yellow.
I’m planning on bringing yellow into my species hybrids. I’m looking for the best source of genetic material.
Unfortunately, a “modern” yellow is going to bring along a lot of “baggage” from its other ancestors. I am hoping that Peter Harris’s R-15 will allow me to introduce yellow in a relatively pure form. The problem with this approach is that it will probably take several generations to get repeat blooming plants.

I am particularly hopeful that the tetraploid acicularis X R-15 cross will be of use to northern hybridizers.
This year I had germinated all yellow seedlings from an OP of a yellow rose at my work.
The rose had lots of matured hips and even flowers in mid December 2005. 46 Seeds/from 3 hips were stored and 21 germinated April/may. About half of them had flowered until now, and all had been yellow.
The problem though is that I don’t know the name of the parent rose, and it is surely (again) not a new one as well. Pictures of the parent rose and the first 3 seedling flowers can be seen on the link below.

Im still waiting for the R. acicularis/R-15 to bloom Henry. Im hoping to put New Year x Baby Love on it. I like the fact that the stems and foliage are very smooth on it. Also, zero spray on it has yielded zero disease.
Jadae, of the 6 (tetraploid acicularis X R-15) seedlings that I have; only the one pictured in the link has bloomed so far. No one else who got some of the seeds has reported in.
Robert, I forgot to add Selfridges. I have three seedlings of it in my test spots this year. They are all Selfridges x Freedom. Selfridges is very healthy and sets seed easily. However, it is not a super strong yellow which is why I never suggested it. It has nice form, though! It’s major flaw, in my opinion, is the lack of good branching habit. It is 8’ tall by September.
Also, you may look for Aalsmer Gold. It is bred from Selfridges and has apparently been used as a female parent before.
I forgot another. Golden Holstein. It is bright gold and sets seed well. The negative aspect is that I dont know how the seedlings commonly turn out and Im told that it dislikes cold. It grows well here, though.
I’m back to leaning toward ‘Carefree Sunshine’. I can only add a couple this season. Golden Hostein is intrigueing but again I can’t tell much about it’s pedigree. Selfridges looks like it comes down from ‘New Day’. It would be nice to get something derived from R-15 but I have no idea how it would behave in this climate.
Morning Has Broken is very resistant to BS even more then Carefree Sunsghine and it sets hips easily. Of course, it doesn’t have HT form, but you said you want resistance.
Olga
Thanks Olga, I see Cliff Orent has ‘Morning Has Broken’ in my local area. I’ll make a note to ask him about it. I already have a couple of the Moore miniatures derived from ‘Gold Badge’ and I have ‘Golden Celebration’. I might has the basics of that gene pool already but hip set is a huge issue in yellows here. Many that work elsewhere simply won’t cooperate here. I dallied a bit with ‘Captiain Thomas’ this year but have no idea what to expect as far as germination goes. I don’t usually chill many of my seed but in the case of ‘Captain Thomas’ it seems more imperative?
Robert, ‘Henry Fonda’ has only worked for me as a pollen parent. It seems to produce the darkest yellow for me of anything that I have tried, but even as a pollen parent fertility seems low, with lots of hip failure. I tend to mix it’s pollen with other very different pollen so that I can distinguish the resulting seedlings. That way I don’t waste time on hip failure when using ‘Henry Fonda’ alone. I have been happier with the fertility of seedlings of ‘Henry Fonda’.
Other thoughts, Tom Carruth has said that ‘Top Notch’ is a good seed parent. This year I started using ‘Julia Child’ and it seems fertile both ways. Previously, I used ‘Singin’ in the Rain’ extensively, and it does produce some yellows. I like it’s habit of producing floriferous seedlings. I never did like the form that I got using ‘Midas Touch’.
Jim Sproul
Thanks Jim, I had the same experience with Henry Fonda and attributed it to perhaps using it too late in the season. I’ll try again earlier next year. ‘Top Notch’ is a thought. I always thuoght it was a very presumptuous name. McGredy must have a lot of faith in it? Apparently there are some disease issues?
‘Julia Child’ is another possibility. Tom Carruth spoke highly of it at our society meeting. Please let me know if you have any success with it?
Are you back from your trip or have you left?
Yeah you can see the New Day in Selfridges by the symmetrical foliage and the linear stems. The blooms are about twice the size and it doesnt mildew.
Thanks Jadae, I see Cliff grows ‘Selfridges’. I think I’ll check that out.
I have had Selfridges (Kordes’ Rose Berolina) for many years. I try using it both ways each year. I have nothing of any interest so far.
This year I have 2 pollination bags on it.
One is labeled as having Carefree Sunshine pollen placed on it on 7-10-06. The stem below the hip is just starting to change from green to yellow.
The second is labeled as having Home Run pollen placed on it on 7-24-06. The stem already has turned mainly yellow.
I do not keep records of where I used a pollen so I cannot tell you whether Berolina pollen has taken this year; but from my previous records that I have on my web page, I did not see any successful hips listed (either way).
When I purchased Berolina I also purchased Germiston Gold. As you can see from my link http://home.neo.rr.com/kuska/hips-2003-season-sort-seed.htm
it worked both as a seed parent and as a pollen parrent (on my web page use the word Gold in your find command - I misspelled Germiston).
This year I have 2 pollination bags on it. One is with Carefree Sunshine pollen and one is with the Sevillana (Meilland) pollen. Both look good so far.
I do not recall any previous “keepers” using Germiston Gold.
