This year i am trialing several Solanum Cheesmaniae and Solanum Galapagense accessions and may use them in breeding projects. This is the year of my big tomato growout, not just for wild tomatoes. And the first year i have grown any tomatoes in several years, but i think it will be a good one. The good news it will be a good growing year. The bad news it will be one heck of a hot, dry, wildfire year!
These are the lines i am most interested in based on the information provided.
Solanum Cheesmaniae: LA0428 - heavy anthocyanin, exerted stigmas LA0429 - antho, flowers large, exerted stigmas, visited by carpenter bee LA0437 - orange, anthocyanin, carpenter bee
Solanum Galapagense: LA0530 - orange-brown fruits LA1137 - Aromatic? LA1408 - only one reported as having RED fruit (cross?) LA1410 - purple fruit
Some of these i've had good germination, others i've had a hard time. I'm using the 3% bleach method to help the seeds. In my second batch i planted some without the bleach treatment just to see if the tortoise germination myth had any merit. One accession sprouted fine without the bleach treatment, the others did not. I am now resowing those with bleach treatment.
I am out of seed for LA1137, but i have ONE seedling growing, so i guess i will just have to take care of that one plant.
I will try to take some pictures of my seedlings at some point.

I decided to try and request some even though i don't know if its a trait i'd be interested in or not or if i have any room left to plant it this season. But here is the reply i got. I guess i'll go ahead and ask for him to send any or all of the european varieties he mentions and plan to share half of it with you?

Yes! A warm welcome to both old and new! Always nice to see lots of new people joining the forum lately and always nice to see old names return! Love to see more people jump in and see lots of threads light up. Would love to see new people post something even if it's just a quick question or a simple hello! Where are you from?, what climate are you growing in?, what brought you to the forum?, any garden projects your interested in?, interested in breeding your own custom crops?

Great Tell us informed about what it will produce ! no idea really. From what it sounds like it might not be a remarkable trait. Here is the only photo i can find: On the other note though, here is a place you can order seed for the orc orange seed gene. If someone orders some i'd be interested in seeing pictures of it and whether its a trait i would want to have. bioinf.scri.ac.uk/germinate_pea//app/core/passport/view_accessions.pl?accession=373

Joseph Lofthouse, I just sent you my last remaining seed for Nordost Fruhe Grune peas (which translates as northeast early green). They are rather small seeds so in the end i didn't find much use for them, but they might work well as an Austrian Winter Pea. Obviously the name says that they are early. Probably very cold tolerant. www.schreberarten.ch/Pflanzen/ErbsenKefenLinsen/Erbsen.htm

Can you describe more about what the orc gene would look like if i encountered it. The salmon-flowered pea seeds are often pinkish to a light orange, but i don't know if that is the orc gene. They certainly don't have orange leaves. This year i finally got my hands on the orp gene from IPK gatersleben genebank. It's called "orange pod" on the seed packet. data.jic.bbsrc.ac.uk/cgi-bin/pgene/default.asp?ID=515

Honestly i still don't know if i fully understand it. I don't think it was your explanation steve, i think it's just my brain isn't ready for such a concept. In any case i hope to evaluate my pods for fiber and strings better this year. Perhaps i can identify some good lines that i should use for breeding. Sometimes the best way to learn about something is just by doing. Some things just cant be explained they have to be seen and felt and experienced. edit: steve1, i think i've seen you mention the parchment staining before in your thread. Can you resurrect that thread and show us more. What chemicals do you use for the staining? Are there cheap easily obtainable chemicals which would do the same job? I know in biology labs they use a blue staining technique for microscope slides, i assume that's what you are using. Would iodine work? I know it stains starch, so i assume not.

Aside from appearance, what is the point of a white crookneck? I'd think the carotenes in yellow/orange crookneck valuable nutrition. Perhaps you have ample carotenes, in any event. Purely for looks. Just because i'd like to see something different. A dark skinned when mature crookedneck might also look striking. But there are other possibilities like crossing delicata winter squash with crookedneck and then backcross for crookedneck appearance. If that were to happen you could get a brown cream and green striped crookedneck and who knows that might affect flavor too. The point is, i'd just like to see a little more variety in summer squash than i currently do.

Sounds like a good project. Best of luck with it.
It's interesting that you mention powdery mildew problems with summer squash. I don't grow summer squash as much as i do winter squash, but i can't say i've ever had problems with it. I only ever plant bumpy crooked neck squash though and by the time powdery mildew would even set in it would be late summer or fall and i don't think i would be harvesting summer squash at that time anyway. I've had powdery mildew attack the winter squash, but generally i'm able to harvest squash despite that. Again, i've mostly only seen it late in the fall. Although i will say that some years may be more powdery mildew than others based on the weather that season. Last year was a hard year to grow squash, but it didn't seem like powdery mildew was that bad. A long time ago though there was one year that powdery mildew was so bad that it was attacking all the field bindweed heavily!
I don't know if i will get to it this year, but i would like to start a summer squash breeding project where i breed a white skinned bumpy crookedneck squash. Bumpy and crooked, but instead of dark yellow its white.

When you posted the photos i did wonder if the hyper-tendril trait was missing from your packet. It's entirely possible that you have a strain that doesn't have it, whether intentional or not. Some people like Hyper-tendrils and some do not. Also, as Phil mentioned Sugar Magnolia was released rather early while it was unstable and all random amounts of each version were present (hyper, normal, and parsley). Even Alan himself says that he will use his "good seed" first and if that gets low he will send out his backup seed which has more of the off types. So who knows. It is kinda funny and weird though that you would get 4 tendril-less in a row and no hyper-tendrils at all so that's a bit odd. Not sure whats going on there.
Regardless i hope you find Sugar Magnolia to be a nice variety. It still is one of my most robust and productive.

keen101 (Biolumo / Andrew B.) - the constricted pod phenotype as related to Mendels work relates to a single recessive gene (though as his papers were lost they have not been able to work out whether it was pp or vv). In the 1860's the single recessive was the standard snow gene type and it wasn't I believe to about 1925 (Wellensiek), the no parchment ppvv genotype was recognized from a cross. I'd have to say from my testing the very small amounts of parchment seen in some of the single recessive genotypes would likely make no discernible difference to edibility. I will post a few more stain pics in the thread I have posted previously. Thanks Steve, I'm not exactly sure what all that means. Are you saying that you can get a constricted pod that is not low in fibre? If so, that's somewhat interesting. Whether the pp or vv genes are involved or not i'm aware of very few pea varieties that have constricted pods. One might be Carouby De Massane, but i believe i've seen inflated versions too. I'm not really sure whether a snow pea with constricted pods or inflated pods are more advantageous than the other. Perhaps just personal preference? In a big pod like Carouby de Massane i suspect inflated pods make more of an impression than constricted, but i have no idea if that affects fiber or edibility characteristics.

I am growing Sugar Magnolia snap pea for the first time this spring and 4 out of the 18 plants are completely tendril-less. The seeds came from Adaptive Seeds last fall. I know a lot of people here have grown this variety. Has anyone seen this phenotype in the variety? This seems like an undesirable trait, so I'm assuming I should not save seeds from these plants, or maybe even cull these 4 if I decide to save seed from this batch (I still have more seeds I could plant in the fall). The really odd thing, is that the 4 tendril-less plants are all right next to each other near the middle of the 7' row. So, I guess my real question is: Could this trait be environmentally triggered (by some extra stress such as chemical contamination or much rockier soil in that tiny section of row), or was it genetically predetermined in those seeds. The odds seem very low that I would have unknowingly planted all 4 tendril-less seeds right next to each other. Thoughts? Hey Farmer Mike, Yup. Lets see if i can organize my thoughts into a coherent sentence.. Basically the original cross Alan Kapuler made to produce his his hyper-tendrilled aka. semi-leafless peas like Sugar magnolia started with a cross with a parsley-pea type (which i call "a double recessive"). The parsley pea types actually possess two recessive alleles, one which codes for an extra amount of tendrils ( af) and the other ( tl) which codes for tendrils converted into leaflets. This second one is actually called "tendril-less", so that's pretty easy to remember. Sometimes i believe it's also referred to as "vetch" or "acacia" type plants. data.jic.bbsrc.ac.uk/cgi-bin/pgene/default.asp?ID=669But the short answer is yeah, it's a recessive trait that sometimes shows up in Sugar Magnolia. But sometimes you will find partial expression of it as an environmental, and not a genetic trait rarely on other pea varieties from time to time. It's up to you if you like that genetic trait or not. I personally wouldn't save seeds from any like the one in the picture because it neither has hyper-tendrils or even tendrils at all. However last year i had a parsley-type that i did save seeds from despite it being a tall pea with few tendrils to support it. I didn't notice it until late in the season because it's hyper-tendrilled siblings held on to it.

Potato Colleagues, Spring has sprung! It’s time to start thinking about ordering stocks from the US Potato Genebank. If you have already ordered tubers and have not yet received them, we will be shipping tuber orders out in the next two weeks. If you haven’t ordered tubers, we still have a limited supply available from our 2015 greenhouse fall tuber harvest. They are listed on our web site and we will be happy to share tuber samples for research and breeding purposes while supplies last. If you want to look over the list of tubers still available, you can view the tuber list from this web link. We’ve recently added five new clones to our in vitro collection (listed below). More detailed information for each clone can be viewed from this new clones web link. 1) CALIFORNIA GOLD - Developed by Carlos Quiros, University of California. Reddish-brown skin, russet, with pinkish eyes, flat oblong tuber and deep yellow flesh. 2) DOUBLOON - Developed by Carlos Quiros, University of California. Light brown skin, russet, round tuber and dark yellow flesh. 3) GOLD NUGGET - Developed by Carlos Quiros, University of California. Brown skin, slight russet, purple eyes, roundish smooth tuber and dark yellow flesh. 4) INKA GOLD - Developed by Carlos Quiros, University of California. The main attribute of this `Inka Gold' is its deep yellow flesh color. 5) SARPO MIRA - Developed in Hungary. Long to oval tuber; red skin. Late blight resistance. We have nearly 5,000 accessions of over 90 different wild and cultivated potato species available as botanical seed and nearly 1,000 cultivated or breeding stock materials available as in vitro clones. Listings of these stocks can be accessed from this holdings page web link. If you are interested in receiving any stocks we have available, please feel free to send us an Email, give us a call or enter it into the new GRIN Global database ordering system.

I think gravedigger is a variety that is currently only available in England from the Heritage Seed Library. But there are a few people on this forum who are nice enough to try to go out of their way and might send you some if you ask (maybe galina or robertb ?). That's how i originally got Shiraz and Bijou. Both fared poorly, so i really don't grow them anymore. This year Bijou is mixed into Carouby De Maussane and i will just select for whatever grows best of that type, but i am also growing a competitor from the Kapulers named Green Beauty so it may or may not replace both of those. Amish Snap seemed to have ok snap pods, but it was consistently one of the worst growing peas in my garden that it has now been selected out by natural selection. I will not grow it again. I'm sure there are other snap peas that will fare better in my climate. I have yet to trial snap peas specifically yet, but i am trialing one a year. Last year i tried Sugar Daddy Bush, this year i'm trying Sugaree (another Kapuler bred variety). I think this year i will try to pay more attention to pod fiber. There was another thread with a discussion of ppvv fiberless genetics. I too would like to know how to identify a ppvv pod versus a ppVV or a PPvv pod that only has one set of fiberless genes as i'm a little confused about that. A few years back i grew Dwarf Gray Sugar from the Seed Savers Exchange and found that 80% had non-constricted pods and some that had constricted pods. I decided i wanted the constricted pod version to have for mendelian genetics nostalgia and so i only saved seed from those. I found out later that i may have inadvertently selected for the fiberless "pulverise to dust" trait. Not sure if that means these are ppvv and have two fiberless genes or only one.
