It is from a cross of "N144-2" X "Basye's Thornless". The Hulthemia seed parent, "N144-2", came from a cross of 'Pearl Sanford' with one of my earlier Hulthemia seedlings. As can be seen in the photo, this seedling blooms a lot. And like most of the "Basye's Thornless" seedlings, it seems to be quite vigorous and fertile. "Basye's Thornless" is a pink, 5-petalled, once blooming, thornless rose bred by Dr. Robert E. Basye and has good black spot and powdery mildew disease resistance. HelpMeFind has good photos of it - click "Basye's Thornless" to see it. Also worth noting, "Basye's Thornless" appears to be the same rose as 'Commander Gillette' and "Basye's Legacy".
Though my main interest last year was in crossing "Basye's Thornless" with many of my Hulthemia seed parent seedlings, I also crossed it with several non-Hulthemia seedlings. Below are 3 coming from a cross where "L56-1" was the seed parent. "L56-1" is a seedling of 'Thrive!' that I have mentioned elsewhere.
By now, you are probably seeing the pattern, that "Basye's Thornless" produces lots of pink seedlings. Pink is definitely very strong in this line which is why I was surprised when I saw the following seedling that came from a Hulthemia cross (no blotch on this one), but it's white.
Yellow is an even more difficult color to get. In the 3 photos below, you can see some yellow coloration. These seedlings might be useful to get yellow thornless seedlings in the next generation. The first one has 'First Impression' as a grandparent. The second one is from a yellow Hulthemia and is showing just a hint of the Hulthemia blotch (it also has 'First Impression' in it's lineage). The third photo below is a bit blurry, but I included it because this one has the most yellow coloration of them all seen at the base of the petals.
Below are a few more from Hulthemia crosses that are showing better blotches. The second and third ones shown below are sister seedlings from the same cross. The third one appears to be closer to a mini in size and is another one of my favorites.
In this years crop of "Basye's Thornless" seedlings, it appears that 75% or more have been non-remontant (meaning that they will not bloom this year and may take 2 to 3 years or more to bloom for the first time). The majority seem to have few or no thorns, but I have noticed a significant number of them having little bristles, or stubble that actually does not feel very sharp, so they are almost as easy to handle as the thornless seedlings.
In closing this post, here is a more recent photo of the seedling show at the top. I am very happy with it's apparent good repeat blooming power.
Can you root cutting anytime or only in the winter?
ReplyDeleteI am very impressed with your seedlings all are pretty. I haven't tried planting seeds yet.
ReplyDeleteHi Gwen, "Softwood cuttings" (as in cuttings of the above seedling's fresh green growth) are done in the summer time - best during the hottest time of the year (I made cuttings of this one today!) You can also do "hardwood" cuttings. This is done in the wintertime in California where cuttings from dormant stems are pushed into the ground for rooting during the cooler months (this is not possible in climates where there is snow).
ReplyDeleteThank you - and best wishes in planting rose seeds. It's a very fun hobby.
Hi Jim, my name is Andrew and just like Matteo who commented on your previous post, I am also a young rose breeder (25). I've been growing roses for years and have tried my luck at hybridizing for 3 years. It was only this year that I was finally able to see some of my crosses from pollination to seedling bloom. By the way I live in the hot humid south of Prairieville Louisiana, in my opinion a perfect place to carry out rose hybridizing because black spot and other diseases run rampant! Out of my many seedling that sprouted this year only 3 champions emerged that were able to handle our late winter, damping off, black spot, and currently our extreme summer temperatures. I would love to show you my work and have your opinion on the litterally hundreds of crosses I've made this year. In fact, as I seek to be a professional plant breeder and make a career out of this, I would like to humbly ask you if you would be my mentor? I have been reading your blog for a while and I am so impressed by what you are doing, and by the way I LOVE Thrive! I've only gotten one this year and have made several successful crosses on it, such as using the pollen of Shafira Asma, Stormy Weather, Easy Does It, Pround Land, Peggy Martin, Walking On Sunshine, and Honey Perfume. As the creator of Thrive! what kind of progency do you think I will obtain from these crosses? Each one is labeled and growing fat, and note that I had MANY more hip drops than successful fertilizations. Anyway, sorry if this post is too long and please consider being my mentor. My email is xbarocco@gmail.com.
ReplyDeleteHi Andrew,
ReplyDeleteThank you for your comments. I am humbled by your request and will comment more on that through email. You can expect some interesting seedlings from those crosses!
Are Roses true to form,when grown from seeds and can seeds be taken soon after the Rose has fully bloomed and withered?
