How to know how many plants I need for breeding?

Right now, I've created a list of all the crosses I'd like to make this coming spring. This is my first true year of breeding, so I don't actually have any of the plants yet. I'm planning to buy them soon so I have them somewhat established this year for next year. The problem I'm coming up against ...

Re: I'm new here, so I'd like to say hi!

Hey, Chuck! Those are all great questions. I'll go through them one at a time. What is the USDA climate zone? I am in 7b which I believe is similar to Washington D.C. (but that may not be right). What kind of soil you are working with? I'm not entirely sure what kind of soil we will have at our fiel...

Re: I'm new here, so I'd like to say hi!

Thanks, rosegeek, for those ideas! I'll definitely do a bit of research on those and see if I can get some of them.

Re: Seedling

Regarding Highwire Flyer, I want to note that the stunning rose on the cover page of the A.R.T.S. webpage (linked to in another post) is Highwire Flyer. I hope they can look half that good up here in Zone 3. I noticed another young seedling of the same cross that also has the metallic foliage. In o...

Re: Is this color prediction chart accurate (or useful)?

I'd say the chart is somewhat useful if you look at the percentages over 20% as there's obviously some general trend there that's occurred over a bunch of different roses. You just have accept that unexpected results can and do happen. As the chart shows though, if you're looking to maximise your r...

Re: I'm new here, so I'd like to say hi!

Josh, The early 19th century was a strange and exciting period. Trade with the far East was expanding, and many people would receive plants that they had no idea how to cultivate. Thousands of such plants were packed in boxes and delivered to nurseries with no return address of explanation of where...

Re: Is this color prediction chart accurate (or useful)?

Originally created by Steve McCulloch I believe. It was the results the creator researched. Okay, that makes a lot of sense. I guess if I want to use this as a tool, I'd need to do some digging as to which roses he used for breeding. Then, it can give me a slightly better idea. Otherwise, the chart...

Re: Is this color prediction chart accurate (or useful)?

Phew! That is the sort of work that really should be done on a computer, but I did it all before home computers were available. I was lucky to have a pocket calculator back then. Among other things, I learned that published reports of parentage are not entirely reliable. And some alleged "sports" w...

Anyone going to the ARS Convention in Oct?

I just signed up for the ARS convention on October 4-6, and I was wondering if anyone else will be there.

I'm trying to connect more with some in the rose community, so I'd love to meet up in person!

Is this color prediction chart accurate (or useful)?

As I've been doing research on planning/selecting rose varieties for crosses, I came across this chart for predicting the likelihood of colors for the cross.

Does anyone know if this is either accurate or useful?

Re: I'm new here, so I'd like to say hi!

Wow, Karl! I really appreciate this information! I've been trying to read up on as much rose history as possible, and somehow I never came across the notion that there were more than 4 Chinas used (the Stud Chinas). I'll definitely check out that thing on Archive.org. I've downloaded quite a few boo...

Re: I'm new here, so I'd like to say hi!

Ah, yes! I couldn't tell if you were talking about the 4 Chinas or Chinese species roses that some of the other posters referred to. At this point, my goal is to focus both disease-resistant roses and also trying to bring in some interesting traits from species roses--potentially ones rarely used. I...

Re: I'm new here, so I'd like to say hi!

Not to try talking you out of looking into the China roses, but Paul Barden, who made some rather beautiful roses, has often stated that black spot was introduced in to many of his lines when Chinas were added. Does that prevent me from messing with them? Nope. Just a piece of information to store ...

Re: I'm new here, so I'd like to say hi!

Thanks, everyone, for your advice and encouragement! I really like the idea of testing out Kordes and Canadian Explorer roses. I'm not entirely sure I can find the Explorers here in China (I'll have to ask my wife). However, I really like the idea of testing out using species roses from here in Chin...

Thanks for your response! Yes, I really liked your section on record keeping in the Next Steps booklet. I'm using it as a basis for creating my system. At this point, I feel like I may be keeping track of too much information, but I'm sure I'll figure out what info is good is which is unneeded as I ...

Hey, I'm Josh. I got into rose breeding this year, and I've been reading/soaking up everything I can find. I've been lurking in the forums for a few months now, but I'm only now posting because I haven't felt ready to be involved in any serious conversations yet. I'm originally from Michigan, but I ...
