I saw Goldini growing at her farm in August, so she's still working on it. I think she has more correspondence than she can keep up with.

Azul Toro is now clean. I just confirmed that yesterday. I am now trying to propagate enough to grow a crop this year.
And I found a source of NyA with the help of the Kenosha Potato Project, so I hope to start work on it this spring.

I have been trying for several years to find a remaining source of Tom's Negro y Azul (the clone, not TPS). I would like to clean it up if it still exists. Every lead I have followed so far has been a few years too late. I am also generally interested in cleaning up other TW varieties that still exist.

I'm far from an expert on beans or their viruses, but there are definitely viruses that infect bean seeds. Probably the most well known is Bean Common Mosaic Virus, which can infect 80% or more of the seeds of infected plants and also can transmit through pollen. Meristem tip culture and electrotherapy are two techniques that can cure this virus. That said, for plants that grow true from seed and have a seed infection rate of less than 100%, the most cost effective route would generally be to grow 100 seeds and then test all of the seedlings for the virus by ELISA. You would then just keep the ones that test negative and propagate a clean crop. That route has the virtue of not requiring a TC lab and skills, which is a fairly substantial investment of time and money.

Awesome. Registration is disabled, in case you aren't aware.

Nope - the virus infects the embryo within the seed. Possibly heat treatment, but there is no way to test it without an affordable test for DMV.
I'm not sure that it is really worth worrying about. Research has found that commercial sources of dahlia seed are routinely infected, which probably means that this virus is ubiquitous.

This is very interesting. I wonder if the hybrid might have fertility problems though. If these two speices have diverged genomes, then you might get to a point where the chromosomes don't pair up properly. Let's say that baileyi is the B genome and grandis G.
Baileyi x Grandis = BB x GGGG = Wilsonii BGG
Spontaneous doubling yields Lingholm = BBGGGG
Baileyi x Lingholm = BB x BBGGGG = Hybrid BBGG
Grandis x Hybrid = GGGG x BBGG = BGGG
Now you have the potential for wacky results, depending on how different the genomes are. You might get the G chromosomes forming trivalents and the Bs forming univalents.
Or, if they aren't too different, it might all work out.
Please keep us updated!

I'll try to get a picture tomorrow. The symptoms tend to be worse in early growth than at maturity, but the leaves are a bit rugose with irregular yellowing. I don't find it to be much of a problem and it wouldn't bother me if I weren't selling seed. Unfortunately, dahlia mosaic virus transmits reliably through true seed.

Hirt's is a totally shady outfit. I have had to repeatedly go after them for stealing my images and using them to try to sell varieties that aren't the same. I just looked at their Amazon product and they are no longer stealing my images, but the images that they are using are just lifted from Google. Who knows if what you get will match at all?
I think that the variety Late Red is dodecaploid, but I have had no luck counting yacon chromosomes - there are way too many jammed together and overlapping.

The TC variety appears to be Early White based on photos that I have seen of the flower. I have been told that the purple yacon that circulates on eBay and Amazon is the same variety, just with a picture of Morado yacon used to advertise it. Of course, it could be a different seller this time.
Seven months is about the minimum time to a full yield.

That's just the normal status page and shouldn't cause you any trouble. The current web site problems are a result of moving the site to new hardware. Out of an abundance of caution, I ran a malware checker on site and came up with nothing. If anyone else gets a warning, please let me know.

That's pretty unlikely. What software are you using?

Is your plan to cross the Sli gene into new domesticated diploid varieties?
