In [2017] I bred A New Pea Variety With Purple Seeds!

20170919_180135

 

these are new F2 seeds recovered from some pea crosses i did i think in spring/summer of 2015. So two years ago. This one is the descendant of a cross done between a rare, and nearly extinct variety of pea that has a dominant gene for having a purple testa color over the seed coat. The parent variety called ‘Purple Passion’ has small round dark purple seeds and grows on thin wispy and pathetically weak vines. Hardly seems domesticated at all. The other parent of the cross was a “super dwarf”, or Extra Dwarf as some literature calls it, of a short (1-2″ tall) but robust pea with thick stems, big leaves, large seeds, and a charming personality. For a plant that is. Not that plants have personalities, but whatever. The result in the F2 generation is this. A large good sized seed with the characteristic dark purple testa seed coat color. Pretty awesome. I’m excited to furthur grow this line out and see what it becomes. This is different from the Brick-red seeded peas known as ‘Biskopens’ or ‘Sweedish Red’, which are a brick-red color rather than dark purple / violet and which is a recessive trait rather than a dominant one. Biskopens is a neat variety in it’s own right, and i have recovered some interesting F2 recombinant offspring from some crosses of that variety as well.

Not sure what i should name it yet. Depends on what it turns into really. Assuming i was able to recover the “super dwarf” genetics at some point i might name that substrain something like ‘Purple Midget’ or something like that. haha

Growing Watermelon Landrace in Colorado 2017 Success!!!

1504913770436

Most of the watermelons are done for the year and eaten already. Many of them were good tasty Canary Yellows. One Salmon-yellow and one Pink were so/so. I’m trying to not save seeds from now on from any that taste bland like the salmon-yellows. Or others that grow poorly. I think i will also start selecting against those that have bacterial rot at the flower end and those that split open. But i’m happy in the direction these are headed. I have a side breeding project where i am letting some Colorado red-seeded citron being pollinated by the landrace watermelon. I’m hoping that in the future that leads to a more cold-tolerant yellow fleshed red-seeded watermelon strain. Some seeds from those are all crazy colors this year with some partially red-black and others with unique gray spots. Just a side project for now.

Generally the small bowl-sized watermelons are from my garden. I had the opportunity to have a small local organic farmer grow some of the landrace watermelons for me in fertilized soil and on black plastic. Those ones grew a little bigger for him. I was able to purchase and collect a few of those back. The long one looked like a yellow-fleshed Lofthouse Charleston Gray strain to me… but i don’t know for sure. I cut it open a little early. Apparently the long ones take longer to ripen so the dry three-tendril method didn’t exactly work on those, but it did for my small round ones!

All in All i’m happy to finally be able to grow decent sized tasty watermelons here in the heart of Northern Colorado. Where few are able to succeed at growing watermelon at all! Success!!!!

A Teosinte Christmas in Colorado

So, i know I’ve blogged a bit about experimentally growing Teosinte in my post about growing prehistoric corn and also in my post about differences between teosinte species. Both posts have gotten quite a bit of traffic over the years and have brought people to my blog who are interested in Teosinte specifically.

For those of you who don’t know Teosinte is a progenitor to modern Corn (Also known as Maize), which is still able to interbreed with Corn. Some teosinte is annual, while others are perennial (or maybe bi-annual). There are many people who are interested in breeding perennial teosinte with corn to make perennial or bi-annual corn.

The major problem with trying to grow Teosinte in a moderate climate as here in Colorado in the United States is that it is adapted to grow in the climate of mexico and our growing season just isn’t really long enough. Even more so since Teosinte is day-length sensitive and does not even start to tassel, silk, and pollinate until the days get short and the sunlight shifts deeper into the red spectrum. By the time that happens here it is usually around August and often we get snow by September or October. Definitely not enough time for Teosinte or Corn seeds to mature and dry down for saving. …Or is it?!

Well, this year it just happened to turn out just barely long enough. I’m calling it my Christmas miracle! haha. I think it was a combination of it being a La Nina weather year with an unusually warm fall with no snow until here in December. But also with the fact that i dug up my clump of teosinte plants and put them in a pot in the garage. Though they were a bit unhappy in the garage and were touching the ceiling.

Still i was able to keep them in there long enough to hand pollinate them. But to be honest i thought i had again failed to get viable Teosinte seeds. But when the plants were dead i went out and happened to find some! Above is a picture of what i believe to be seeds of ‘Zea mexicana’ teosinte seeds.

If there is one moral of this story that you should take away it is this: Never give up even when everyone else thinks you are crazy or tell you that what you believe is impossible. I learned this in gardening from my friend Joseph Lofthouse of Utah. He has had success with so many of his unusual crops that no one else in his valley of Utah is able to grow. He often starts with many varieties of a plant as possible and grows as many as he can. Often more than 90% of them die or fail to produce seeds. But he only needs a few that do. Once he gets seeds he can start to effort to plant them year after year and adapt them to his climate. If they still fail to thrive he lets them die or culls them off himself. But he has a variety of unusual crops, such as Landrace Watermelon adapted to Utah (and by extension Colorado), Landrace Cantaloupe, Landrace inter-species hybrid squashes, Tomatoes that are self-incompatible and are highly attractive to bees (modern tomatoes are not at all and are highly inbred), and more.

 

On the left here is a photo of one small cob of a teosinte hybrid (zea diploperennis-corn hybrid from the USDA) pollinated with what i believe to be flour or field corn pollen. On the right is the same teosinte-corn hybrid cob line but i believe this one was self pollinated with its own pollen. It seems to have popcorn heritage as the seeds show popcorn / flint corn characteristics.

Here is another strain of day-length neutral teosinte (decended from Zea mexicana) that a collaborator Joseph Lofthouse of Utah is growing and having success with. I believe he got the seed originally from NativeseedsSEARCH in Arizona. He decided to test if it makes good popcorn.

Here is my Teosinte clump in the summer of 2016.

Here is the same spot with snow on it now in winter.
