I don't know who has it in Africa but it is readily available in the Philippines:
"The Institute of Plant Breeding-University of the Philippines in Los Baños, which is producing the seed, is propagating the high-yielding IPB Var 6, which gives a yield that is nearly comparable to commercial white corn hybrid, the DA reported.
“Based on the national corn testing, the yield of IPB Var 6 in Luzon was at an average of 5.84 metric tons (MT) per hectare; in Visayas, 5.45 MT per hectare and in Mindanao, 4.47 MT per hectare.â€
Under Phase I, DA released P15 million for the seed production program where 10,000 bags (at 18 kilos per bag) were produced. Another P25M was allotted for the Phase II, which is good for about 22,000 bags.
Half these seeds have already been distributed to the regional DA offices."
They don't ship seed anywhere, but if you know someone in the Philippines, they can buy it and send it to you.

What's happened to Canada Mike and his high protein corn? I got some from him and grew it last year. Victor Kucyk 2175. Did quite well. Most of it I did not save for seed (eating it) but selected 18 ears from 400 plants for seed for next year. Have not had it tested, but apparently it is even higher in protein that Bear Island Flint, strong stalks, nice high cob set, dries down well, not long season. Selected cobs from earliest dry downs, longest ears, best kernel formation. Should be wide enough genetic base to get it tweaked exactly for my areas. Tom

Some of it is leaving for you tomorrow or wednesday 123....the package has been ready for a week but I was awaiting something else to put in it...the one I am sending to you is higher in protein and the ear is bigger and almost as early, in fact here in Quebec it matured earlier than the VK 2175.
As I think I said here once, one can coax earliness in dry corn dramaticly by using a foliar mix of seaweed and soluble potash, a couple of passes ( sprayings).
Orgqnic soluble potash is available, but another source would be ashes.

Dar, The corn from Minnesota, the one bred for chickens, what method would you use to cross breed this corn into another flint corn?
As it goes typically when I grind flint corn, some of it is just like glass. At home we call this XXgrits. I usually segregate this out and add it to the chicken food.
Flour corn of course doesn't leave this residue, and I prefer it for most uses as I bake more than I boil. However, we do love the flint for polenta and grits, waffles etc.
I would love to grow a corn with higher protein, both for us and the chickens. What would be the best use of 100 seeds? Should I grow them out separately or put them between the rows of another flint? Or flour for that matter?

Is there a reason you particularly want flint corn? Because it is less digestible to chickens than either dent or flour corn.
The corn I received is pretty much a typical yellow dent corn. I suspect it will be medium season given the origin. I would plant two other varieties of corn one short season and one long season with the high methionine corn in between. Then when the high methionine corn tassels, I would de-tassel the corn variety that was closest to matching. That would give an F1 hybrid that carries 50% of the genetics of the high methionine corn.
The next year, I would repeat the process by planting two rows of the F1 cross seed with another row of the high methionine corn in between. This time, de-tassel both F1 rows which will make a backcross to the high methionine corn and should give you a production corn that can be planted the third year and will produce corn that has 50% higher methionine than normal corn. Please note that the reason it is only 50% is because the endosperm is triploid. Heterosis in this backcross seed will be relatively low so don't expect it to be a star producer like the F1 should be.
I'm simplifying the genetics quite a bit. If anyone cares to go into greater detail, it will be a lot more complex than just a 50% segregation in the F1BC1 generation.
If you do a search for "high methionine corn" you will find articles that discuss the logistics of developing poultry feed. One of the articles notes that high methionine corn contains less lysine than high lysine corn. This indicates potential for combining high methionine with high lysine which should be a better poultry feed than either type alone. This is why I requested both high lysine and high methionine lines from ars-grin.
The high methionine corn has two primary genes, one on chromosome 4 and one on chromosome 9. Both genes have to be included to retain the high methionine trait.
High methionine results in a hard kernel corn. It can still be a dent corn, but it is not as soft as most typical dents. High methionine also tends to be linked to deep yellow/orange kernels. High lysine is available in white corn. If combined, selection should probably be maintained for yellow corn. This also has an advantage that chickens fed yellow corn have bright yellow/orange egg yolks.

Dar can the two GRIN corns be crossed together? The lysine and the protein into one corn? To have enough to do the back crosses, I would have to grow them out to increase the amount of seeds to play with.
Thank you, Holly

Holly, That is my major objective this year. I plan to cross the high lysine corn with the high methionine corn and with Cherokee Squaw and with my drought tolerant white field corn. Between the 4, there are genetics that should be highly productive.

Dar, What's the difference between Cherokee Squaw and Cherokee White Flour? Corn is already making me crazy. The temperature jumped to 80+ degrees today and it's time for me to get more corn in. I have 2 more flints to get in, 2 flours, 4 more rotations of sweet corn. I wish I had more carefully read this earlier and had the time to look at those in GRIN. Now that I have I think I could bump up my Italian Ancient Floury or the Florianni Red Flint. I want to increase this corn this year to use next year for this project. Perhaps I can purchase the higher lysine/protein corn from you at the end of the season for next year? One of the problems with my Italian corns is that I have no idea how many days they take. After I grow them out, I'll have a better idea of days till tasseling and silking. My barley and wheat are not quite done yet. I think 2 more weeks. That will clear a lot of space for my melons. I've got 4 empty onion beds to plant. I got to get them cleaned up tomorrow and start harvesting garlic. Attachments:

80 degrees? I'd freeze to death. We are hitting 90+ daily here. I work in the garden for 2 hours and lose 10 pounds of water. This is not a bad thing, as long as I can sweat, I am healthy and don't get overheated.
You don't have to purchase corn from me. Your seed account shows me owing you a few if and when needed.
Cherokee Squaw is a purple and white soft dent corn. Cherokee White Flour is a true white flour corn. The advantage of the Cherokee Squaw is that it is exceptionally vigorous and productive, almost as good as a hybrid. The advantage of the drought tolerant white corn is that it is very productive under dry conditions. I would like to see a good quality white corn that is very vigorous and stress tolerant and has elevated protein levels.

We used the last of our Cherokee Squaw from what you sent us last year along with what we saved from what was planted. Last year was a very poor year for corn so the seed we saved probably wasn't top notch, just the best we had. This year we have doubled, possibly tripled the area planted in corn. Mike wanted to focus on increasing the wax corn, getting enough sweet corn, and increasing the popcorn. We still have some of the white flour seed from last year, but I couldn't get him to put it down for this year. It WILL go in next year though. We need to get flour corn going.
I was pondering grits... Are grits just a larger size grind, or do you have to lye process the corn, THEN dry, THEN grind?

For grits, we grind as fine as the CS BEll will grind. Then I run it through the coffee grinder and sift. Whatever is left over in the sifter, is grits. That's it. I only fool around with lye for posole. Other than that I'm not worried about pelagra.
Thank you Dar. I really want to get the protein and lysine into the Cherokee Flour. I would have tried to get it into the Texas Gourdseed, but that corn takes sooo long. That was very drought tolerant!
Yeah it's 85, I came back for another water jug! Before pulling garlic.

Holly, I think you will like the Cherokee Squaw X better than a typical floury corn. Cherokee Squaw is a soft dent corn more like a floury corn than a typical dent.

I thought the Cherokee Squaw was a sweet corn?
You know, it occurs to me that it might be nice to get a table listing all the various "special" corns we always talk about here and make a check list of all the attributes.... How could you do that though?

I planted a row of corn today with alternating hills of methionine, Cherokee Squaw, and Lysine. If it yields a decent crop, I should have about 5 gallons of crossbred seed. I'm still debating which varieties to de-tassel. That decision may depend on which variety tassels first and which last. The optimum would be to de-tassel the varieties that tassel first and last because the one that tassels in the middle should be able to pollinate both of the others. This would make the most sense if the high methionine variety is the pollen parent.
Cherokee Squaw is a soft dent corn. I crossed Cherokee Squaw X Silver King two years ago and this year am growing out the sweet kernels of the F2 generation. The intent is to develop an se+ open pollinated sweet corn.
