I have found this a hard subject to make simple. But here goes...

Tomato late blight resistance genes are non-allelic

Quote:
Non-allelic genes are genes located at different loci on the same
chromosome or on different chromosomes altogether.


The gene, Ph-3, Chromosome 9
Ph-1 (chromosome 7
Ph-2 (chromosome 10).

Reports are that
Quote:
WV106
carried a single dominant allele conditioning a high level
of resistance to P. infestans tomato race 0 (T0)
(Ph-1)

and that WV700 possessed one or more dominant resistance genes (but is associated with Ph-2)


Quote:
Researchers at the AVRDC identified resistance to late blight from Solanum pimpinellifolium L. accession L3708. Segregation data obtained for resistance do not support the hypothesis of single gene control of the full resistance trait, but suggest that more than one gene is involved, and that these genes interact in an epistatic manner. Differential responses were also observed between the resistant CU-R lines and the resistant CLN-R lines, which were independently bred from L3708. RFLP analysis confirmed the Ph-3 gene derived from L3708 is located on chromosome 9.



The meaning of (genes interact in an epistatic manner )
epistatic (not comparable)

1. (genetics) Of or pertaining to epistasis, the interaction between genes.

I have a lot of self doubt about my work with Late Blight resistance. Since I had great results with sinlgle dominance with WV 700 with my particular strain of it for years 2004-2007. But 2008 is a year that needed homozygous Ph-2 and Ph-3 clones. Mountain Magic has heterozygous genes as a hybrid and it did not survive to the end of the infestation process. Only my most homozygous clone (Ph-2 and Ph-3)survived totally. I will be testing some seedlings from the recent hybrid of WV 700 X homozygous Ph-1 and 2 for this fall. The hybrid would be homozygous for Ph-2 but only heterozygous for Ph-1.


The good news is that I am transferring the genes Ph-2 and Ph-2 into a wide variety of clones such as Black Pineapple, Black Prince, Green Sleeves, WV 700, and many, many more. I've got to remind myself to sow a huge compilation of varieties soon.

The kind of work I am doing with require that I do a large extension collaboration. I will be exploring ideas to that effect soon.

CULTIVATED SPECIES ACCESSIONS WITH TUBER FLESH COLOR

PI #

SOLANUM SPECIES

DESCRIPTION

I am putting this list up on the blog to show that I am involved in many types of research. The list below of potatoes from South America will be dug this August 28 in Vancouver, WA.

I have already collected the inter-mated crosses and the tremendous amount of open pollinated berries from a vast majority of these. The tubers will be of some importance to grow again, but the TPS will be invaluable for many years to come. I could plant many acres of transplants grown just from the berries of this group.

Yes the potatoes will be video taped also as they are dug

CAMPARI -Campari(ng) Descendancies There has been a couple of threads about Campari, namely; http://tomatoville.com/showthread.php?t=12120 http://tomatoville.com/showthread.ph...hlight=campari ...and I thought the topic I am bringing forth deserves a new forefrontation. Question. Has anyone segregated the recombinations for filial generations of Campari. Answer. Yes. I have several lines of Campari descendants to the F-5 level. That is stable enough to assert some expectancies. Just today I extracted a knock off line that looks much like the F-1 Campari and I named it CAM PARIS. Pun intended. As F-5 seed, I should be able to use it in some test hybrids. I am hoping that I have some of the VVFFTN of the hybrid left over in the inbred. I will have to look at the other filial generations to select for the best lines as I am trying to duplicate the reputed flavor of the original. Meanwhile back to the Cross Talk. I have a couple of new selections out of a cross of Green Grape to an F-2 of Campari. The first one is Campptown Ladies, a nice look alike, taste alike of Campari but with the tiny seeds of Green Grape. This one is quite firm. I have F-3 seed of that one. A full sib-Paris green- (a shade of green tinged with yellow) is a Green Grape type, but of a thingytail size with extraordinary flavors and sweetness. It is rather soft like Green Grape and has larger seed than I would like. Both of them will be segregated further in the re-combination to fine tune traits that I want. But in case I don't get those traits I crossed the Paris Green with pollen from Camptown Ladies. The cross should be all red if the CL is homozygous for red flesh. The hybrid seed will be selfed next year to get F-2 seed that will shuffle the segregation even further. I would like to get a firm green thingytail tomato with small seed and great flavors and sweetness. Since Campari has long internodes suitable for greenhouse culture, I will note the growth of the assorted progenies and will send seed/plants to greenhouses for evaluation. I hope to salvage the alphabet soup of disease resistancies. I extracted seed today of Camptown Ladies crossed with Stupice. There is a local love affair with Stupice, therefore I am trying to introgress Stupice into as many kinds of tomatoes as possible in the effort to get adapted PNW tomato varieties with whatever magic Stupice offers. I now have F-3 seed of Black Gaspare, named for Gaspare Campari fame. This is a black thingytail tomato that combines Campari, Black Sea Man, Brandywine, and a chilling resistant line. This combination will be tested for chilling resistance so that ripe fruits can be placed in refrigeration without turning mushy. Yet to be found in my myriads of tomato plots, is some F-2 fruits of the cross of Black Prince, Cherokee Purple and an F-2 Campari. The F-1 had 1 1/2 to 2 inch fruits, round red, 3 locules, and productive as all get out. The plants aren't close, one is in the upper Skagit river valley and the other is in Vancouver, WA., nearly 300 miles from each other. I should not be disappointed in the flavor combos. I have been extracting seed from the F-2 fruits of Campari and Savantas, a cluster roma. The fruits are even more firm than Campari and I will be looking for jointless pedicels, and a variety of shapes. I am not sure what I have, so I am not naming any of them yet. Most of what I like has the Campari shape. I will be looking at some yellow cluster recombinants of Campari crosses as soon as I pick them. Some really tall vines are coming out of the Airy Leaf, Pineapple, Elberta Girl, Campari lines crossed to Green Grape. Yes, all in one pedigree. Most are 2 inch red fruits with green getl indicating the success of the cross. I am impressed of how the Green Grape imparts sweetness and smaller seed size. In these crosses, one doesn't see much of the ancestry of Airy Leaf, Pineapple, or Elberta Girl, just Campari and Green Grape. Maybe I will see those lines show up again in the F-2 generation. I put much effort into this treatise, but if anything ever comes out of this work, you may anticipate what it may be. Tom Wagner

The variety Green Sausage was originally called Green Sleeves by me. I have been crossing an F-5 selection of this clone with some interesting lines to create even more great hanging basket tomatoes that have other colors rather than the green when ripe and stiped Green Sleeves. The vines show a marked determinate growth pattern with a procumbant-prostrate nearly flat to the surface expansion of the canopy.

I took my neighbor down to look at my potatoes and tomatoes with her new video camera. For a lady of 76 years young she was able to capture me extracting pollen from a Nordic October and emasculating a cluster of flower buds of a Boyd Dude potato variety. We were able to put our heads together to put the video on her laptop and main computer. I am thinking of using part of it on my blog and maybe in Europe.

Anyway, I had some extra pollen of Nordic October (one of my best reds) and went to a potato seedling growing in a raised bed. I emasculated several buds of the yet un-named seedling and proceeded to tell my neighbor of the pedigree. I said that the original line was CT8406-33, a chacoense/tuuberosum hybrid with slightly blue rings in a purple skinned white flesh potato that was but one of some seedling tubers lines bred for high glycoalkoloids in the foliage to repel Colorado Potato Beetles. This line was either selfed or OP'ed and the result was Red Cat, a red skinned, red fleshed line that had lots of berries. I crossed Red Cat to a male parent called Lenape, a white skinned, white flesh line with high glycoalcoloids. The cross led to the Negro y Azul, a very black/blue skin and fleshed line that saw it's origin on some certified organic ground off I-5 near Buttonwillow, California. Negro y Azul was crossed to Kern Toro, one of my best reds at that time, a combination of NorDonna and Fontenot. The cross of Negro y Azul and Kern Toro led to Azul Toro, an excellent early blue flesh variety. I crossed the female Azul Toro with pollen from Blue Blood Russet, a cross of Blue Cat and an unknown russet seedling. The resulting cross was named Paint Jar, an inky black/blue with occasional white patches in the flesh. I crossed the Paint Jar with pollen from Dark Red Norland and this created Paint Nor. Paint Nor was crossed with pollen from October Blue, a cross of Nordic October, a red similar to Kern Toro with the exception of additional germplasm from Red October that had ND2912-2R in it....to Azul Toro, previously mentioned. The two seedlings in the raised bed has one I named last week as Mule Skinner Blues. The other had to be named and I thought of Mostly Purple and I serendipitously named it MOSTLY PURPLE as I crossed it with pollen from Nordic October...knowing fully that I had permission to do so.

MostlyPurple made my day by posting on my TaterMater Forum. She has some wonderful photos of nine of my potato varieties in full bloom and displaying a few "new" potatoes of such. Not to be totally jealous of her, I put a couple of pictures up to show one of the areas I grow potatoes and the Paint Jar potato as MostlyPurple has in her garden. I am so happy to have customer approval of my seed potatoes. Do I breed potatoes to be flowers? You be the judge! I have posts on my own blog about the sampler I bought earlier this spring...if anyone's interested http://mostlygardening.blogspot.com/2009/07/potatoes-in-bloom.html http://mostlygardening.blogspot.com/2009/07/some-really-new-potatoes.html

I am clarifying the photos of blue tomato lines below with some detail.
The first photo on the top left is a cross of Green Zebra X P-20 Blue (#10 2-28-09) and is a plant outdoors in Seattle. Rather cool climate and lots of clouds, but still showing the effects of the male parent which is blue. Note the dark blue shoulders of the fruit exposed to a bit more sunlight due to pruning.

The photo to the right 0f it is #24 of 2-28-09 showing the fruit cluster of Blue P-20 x Woolly Green Zebra. This is also outdoors in Seattle. It has just a bit more foliar cover than #10. Note the slight expression of the woolly gene.

The photo under #10 is also #10 but grown in a high tunnel greenhouse in the mountains of the upper Skagit River. This plant has lots of leaves and vine covering the fruit and therefore shows less purplish on the shoulders. Note the very slight stripes developing, typical of Green Zebra crosses.

The photo to the right of it shows the P-20 Blue outdoors again in Seattle. Poor cover is allowing the fruit to purple up. The cross tag shows a fruit crossed to a red tomato with the pedigree of Silvery Fir Tree X Pineapple-Elberta Girl. Nicely cut leaves with extreme woolly leaves and very early. The #25 3-309 tag shows the pollen used for the F-1 seed developing.

The bottom picture shows #9 2-28-09 (Blue P-20) as grown in the high row tunnel greenhouse in the upper Skagit area. Lots of foliage covering this fruit and had to push away about two foot of leaves. The plants are left to sprawl naturally so a a dense shade is protecting the fruit from coloring up. All of the fruits are very immature but show the effects of the blue genes.

I run into folks who rarely ever see potato berries on their potato vines. When they do find them they will ask why they don't see more of them. Potato berries, seed balls, potato fruits, etc., are not how most people see next year's crop like I do, nevertheless, I get a myriad of questions to the point where I see a need to organize a primer of sorts, namely;
WEB TOPIC, WHO, WHAT, WHEN, WHERE, HOW, WHY of Potato Berries.

I talk in circles about my potatoes, losing everybody in the wake, but every now and then........I combine statistics, musings, and experience in hope of making silly, ignorant questions thrown at me seem erudite being I may have a proper response to many questions (implied or impishly) surfacing.

Is there a simple answer to the questions of why some people have potato berries and others don't? No, but that doesn't stop me from using some stats to make it interesting to me. I ask myself these questions similar to this all the time----- all of the 56 years I have been breeding potatoes.

I am also a tomato breeder and I have to save seed. Why can't I just save seed all the time with potatoes? You mean ter say that a potato fella can be a true seedsman rather than just another YouTuberman?

The most obvious question to ask is...Do most potato varieties set berries?....the answer is No! What follows is the evidence, etc.


http://www.europotato.org/display_character.php?char_no=23&character=Berries

1. No berries 463 varieties
2. Very rare 236
3. Rare 288
4. Rare to occasional 74
5. Occasional 134
6. Occasional to frequent 47
7. Frequent 129
8. Frequent to v aery frequent 7
9. Very frequent 14

1392--The number of varieties in the European Potato Database comparing berry occurrence. Yes, it does include a lot of American varieties.



Note that on this list 987 out of 1392 will have either
(1) No Berries
(2) Very Rare or
(3) Rare

That means about 70% of all varieties will not set berries as a rule.

Note conversely, that 21 varieties fall into the last two categories:
(8) Frequent to very frequent or lastly--
(9) Very Frequent

That means that the extreme likelihood of having one of these varieties is just slightly more than 1%, or one out of 66.

Below is the list of the categories (8) and (9):
BF 15
Claustar
Keltia
Kerpondy
Leksands Vit
Mirakel
Record
Aranykincs
Cara
Comle (1964)
Desiree
Dr McIntosh
Granola
Inca Sun
Kameraz
Mayan Gold
Morene
Nemes Rozsa
Orion (1947)
Revelino
Tone

I have grown about 11 of these, soon to grow another one if the tubers arrive, and I would say that Granola and Leksands Vit fall easily into these categories of nearly always having berries, but ones like Morene, Desiree, and Record fall short. The only variety most folks on TVille might have in their garden is Desiree.

I noticed that the Potato Pedigree database shows Granola used 18 out of 25 times as a male (pollen) parent. Conversely, a variety like Agria which never has berries is used as a female parent in almost all of the 66 times it shows up as a parent. There were a few pedigrees that show it as a male but that has to be an error of record keeping. Just try to get any pollen out of an Agria flower.

129- The number of varieties that are listed as frequent in making berries. I have grown about 25 of those in the list and I concur that Atlantic, Katahdin, Vestar, Saturna, Stina, Hindenburg, Boxer, Pentland Dell, etc. fall into this category. Most years you will see some to many berries on these lines but not always. Are any of these in my potato varieties? Yes, all of them, thank goodness!

I think one of the many reasons we have so many varieties listed as having few, if any berries, is that we tend to use them a lot as female parents. They are easy to use since you don't even have to emasculate the flowers. But the unwitting role that plays is that the roll of the dice is creating more and more varieties that are poor berry makers. The genesis of poor berry setters has to do with the maternal lines with historical poor berry setting factoring heavily in the descent of offspring.

I have a habit of selecting potential parents that are good in producing lots of pollen and set their own berries without having to rely on insect pollination or my crossing to them. In other words, good OP lines. which really means good selfing lines. By putting together parent blocks (varieties planted in small numbers in a tight plots) of varieties that are versatile in both directions in a cross, I am creating a population that will carry the selfing ability into the ensuing populations of TPS. That is one reason I have so many good berry makers and most other folks do not. A variety that produces its own berries and for year after often ends up in many crosses, thus is a valuable resource for me.

Too many times a seedling line grown from true seed will produce berries but after growing the plants from tubers will sometimes be reluctant to produce berries. Those lines get dropped quite easily from the parent blocks for the third year. Nordic October is a red variety that has always produced berries even if it was infected with a virus. Since I had the variety cleaned up through meristem tissue procedures, I have been using it in so many crosses that I find it several times in the pedigree of some my recent lines and many of these new lines are great berry makers.
ct
I do believe that during the evolution of creating and preserving cultivars of potato varieties..... that an unwittingly desire for non-berry makers has shifted because the lines that do well under near perfect conditions of agronomic actions just don't have the survival instincts to produce berries. The timing and auxin of the tuberization inhibit the fruiting instincts and the abscission zones abort the flowers since the pull of nutrients is redirecting itself from the plant to the tubers. The big growers kinda like the varieties that are absent berries, and when the plants do set berries it is usually due to an adverse environmental stress such a water stress, injury, tillage, etc.

I will be video recording many of my potato plots this year showing berry formation, crosses, etc. in conjunction with varieties from all over the world with me talking about the attributes of many of my lines that favor berry set.

These videos will show hundreds if not thousands of new clones that will disprove the adage that potato varieties rarely set fruit. It will show the interested audiences that there IS a potato breeder willing to chart a new paradigm of potato production.

I would go so far as to say I am the only potato breeder that gives the number one priority not to disease tolerance, yield, flavor, etc., but to berry setting!



Tom Wagner
AKA TaterMater

This is taken freely from my friend's blog at mutually assured survival dot com. Nice take on my work.

"More protein per acre than soybeans"



That's famed crop breeder Tom Wagner lining up some potatoes that he bred. Mr. Wagner is best known for his tomato "Green Zebra", which is notable for its beautiful stripes and tangy flavor.

He also breeds potatoes. Potatoes are roughly the most productive crop you can grow in most temperate climates. They also happen to be a bit more nutritious than usually given credit for. They are not "pure starch", but in fact contain roughly 2% fairly high-quality protein. The percentage of protein is low, but potatoes are so prolific that you still end up with 500-1000kg of protein per year per hectare of potatoes, versus 164-500kg of protein from soybeans, 98-300kg of protein from wheat, and only 33kg protein from milk produced by cows.

The protein by the way is found almost entirely right under the skin--it's in the yellowish layer you see when you gently peel just the outermost skin from the potato--which is why you should never peel potatoes (you're throwing all their protein content away), but instead always cook them unpeeled and then carefully pull the skin off.

Potatoes are surprisingly rich in other nutrients. They contain the B vitamins and are surprisingly rich in B6, and contain plenty of vitamin C. If they have yellowish flesh then they usually have significant amounts of carotenoids, which are a precursor to vitamin A that your body can use to make vitamin A.
