Watermelon landrace update

The watermelon landrace project actually got more interesting as the summer progressed. As the plants started to bloom I discovered that three of them (two landrace and one Hopi Red) were producing perfect flowers. A perfect flower is a flower which contains both male and female parts. It's capable of self pollinating, without the assistance of bees. I have never seen this before on squash or melons.

I wasn't able to find anything about this possibility online, which made me more excited. The idea of a self-pollinating melon had me bouncing off the walls. Since three plants had the same trait, I thought, maybe it's something to do with my soil? With the help of a friend (Joseph Lofthouse) I learned that this is relatively normal for watermelons, which dimmed my enthusiasm not at all but simply turned it in another direction.

If it wasn't in the soil, but inherent in the plant, I can breed for it. Hehehehe.

Most of the watermelons ripening from the landrace plants are icebox size, which isn't what I wanted. I made a mistake last year and bred in the Sugar Baby watermelon, which is slow growing and produces small melons. It appears that the majority of the plants that survived have Sugar Baby ancestry, but I'm trying for medium to large so I need to avoid taking seeds from any of these. Another interesting thing is that many of the melons currently ripening are misshapen, which I've also never seen before. This may be due to under pollination, but the fact that ONLY the landrace plants are doing it suggests that there's some oddity to the way the genes are combining.

Of the surviving plants, 2 have not bloomed at all. This was rather expected, as I deliberately planted in an area with poor soil and little water in order to select for the strongest. Another has produced only male blossoms. Two of my landrace plants have large melons. One of the two had four flowers pollinate, although two aborted later. It was also one of those with perfect flowers. This will be the primary female parent for this year. One of the two remaining melons was pollinated by hand and should include genes from Hopi Red, my landrace (Ali Baba + either traditional or Sugar Baby), and Joseph Lofthouse Landrace.

Most of the surviving landrace plants took after the female parent in shape and color, but after the male parent in size. All but one had the pale green skin of the Ali Baba watermelon and the seed structure of the Ali Baba, but with varying sizes and shapes consistent with the plants used as pollinators last year. The plants also took after the pollen donor, those with the icebox size melons growing much slower on a less robust plant.

All pollinated flowers follow the same general growth pattern, the watermelon being around 3 inches long twenty days after pollination, 6 inches long after thirty days and 9 inches long after 40 days. The watermelon stops growing when it's close to its adult size and gains that last half inch or inch through the rest of its growing period. By the time it reaches its adult size some seeds have already matured. Extending this tendency out, it is likely that any watermelon can mature relatively quickly once it reaches its mature size depending on environmental factors. Removal of water, not enough sun, a cold snap, may all trigger the melon to full maturity quicker than it would normally go. I'll have to test for this in the future and see if it bears out in real life, but based on my observations it's a real possibility.

Next year the primary female parent will be either my "traditional" watermelon or the Jubilee, introducing one more line into the mix. In 2020 or 2021 the lines will start to stabilize and I should start to see the results of the mixing. That's when the real fun begins, choosing for the traits I want.

I started this particular landrace for a couple reasons. I wanted to learn the principles before I started on any of the major food crops, and I had seeds for several different varieties of heirloom melons.

I am desperately concerned about food security. The majority of the population has no idea where their food comes from or how it gets to them. They're perfectly satisfied that THIS WEEK the grocery store has what they need. With more and more farmland being sold off because of taxes and other economic problems, we rely to a large extent on food produced in other areas and trucked in. Often from other countries.

When (not if) that supply chain stops, we must be able to provide for ourselves. In order to do that we must be able to grow the maximum amount in local conditions, and we can't do that with seeds sourced from the Oregon coast or Arkansas. Even seeds from other desert or semi-desert areas wouldn't precisely fit our environment. They have to be produced here, grown here, without fertilizers or soil additives, and to the extent possible without additional water.

The simplest way to do that, and to make sure that those plants will be able to adapt when conditions change, is a local landrace.

Bean Notes (ongoing, will add to this in subsequent years)

2019

Hidatsu red--resurrected. Apparently two beans matured and I wasn't aware. They came up this spring and were my largest producer.

Rattlesnake--great grower, not a good producer. I'll include it on a limited basis with the climbing bean landrace

Tepary--great grower in the dry garden but just starting to produce end of September. If I get any beans they'll be my first generation, but at this point it doesn't look likely. Try again next year.

Scarlett Runner--growing OK but just started blooming beginning of September. No beans before the first deep freeze. Only two of the 12 plants even germinated.


2018
I've been trying to work with dry beans for a couple years now. Unfortunately, real life information isn't available for many of the varieties I have, so here goes.

The failures first, taking into consideration that I plant sporadically, sometimes early and sometimes late, in different areas. But I don't eliminate a bean entirely until it's been grown on my property for at least two years in different circumstances.

Calypso--eliminated. A black and white bean, probably bred for appearance rather than production. In my garden only one or two beans per pod, many of them empty, and while there were a lot of pods on the plant, that makes harvest a serious problem. Not too productive in terms of real numbers.

Hidatsu Red--eliminated. Planted by the corn last year and failed to produce. Planted by the bean towers this year and also failed to produce. Right now, in mid September, the first beans are just starting to come on. Chances are good that nothing will ripen before the first frost. NO seeds last year, NO seeds this year, end of experiment.

Hidatsu Shield--Ditto.

Whipple--First year planting these. One plant survived. Supposed to be 70 days, but just starting to produce after over 100 days. I'm guessing they need a little stress in order to ripen. I removed the water and got my first ripe beans a week later.

Monos Negros--First year planting these. One plant survived, a good crop.

Oland Brown--First year planting these. One plant survived, a good crop.

Kidney--Fabulous. Planted these last year with 100% mortality. This year one plant survived, and got more off that one plant than from any of the others so far. It ripened quickly, fully finished by mid-August.

Pinto--Good producer. It did OK last year as a climbing bean but produced little. This year I used last year's seeds and it did well for those plants that survived. From the three plants I already have more than I harvested last year total.

Tepary--Two varieties. Neither has produced this year. The blossoms are just starting to come on. They're supposed to be highly drought tolerant so I don't know whether they're getting too much water, too little, wrong soil, not enough sun, etc. I can't find any information on how these are supposed to grow.

Blue Lake--First year with these. A green bean, seeds out of a box. Good production, good seed production.

Rattlesnake--first year with these. They ran rampant over the corn and strangled it. Good production, but they'll be on the bean towers next year rather than by the corn. This is also supposed to be drought tolerant.

Tendergreen--first year with these, and they produced well. Good seed production as well. Low germination, but that's normal for my yard with seeds I didn't grow.

Black Turtle--3rd year. First two years they produced OK, so this year I thought I would do them as a main crop. Chose the wrong area, with only half a day of sun, lots of bugs, and bad soil. Will try again.

Idaho Pink--Established. This was supposed to be the second half of my main crop. See Black Turtle notes.

Great Northern White--Established, didn't grow it this year. An OK producer, half-runner. Many of the plants had just a few beans in each pod, so I took my seeds from the full pods.

Scarlet Runner--I was just given seeds this year so I have nothing yet. These will be planted the first time next spring

Tiny mystery bean--Foraged from the same area as the Scarlet Runner. I have no idea what these are. The beans are tiny and brown, the pods probably 8 inches long. These will be tested next spring.

Is my watermelon ripe?

Figuring out when a watermelon is ripe (i.e., ready to pick) isn't rocket science. See the curlique at the base? In this picture it's green (unripe). When it dries up, the watermelon is ripe.

If the curlique is dry or mostly dry, thump the watermelon. If it sounds hollow, it's ripe. Thump a couple in the area to see if you can tell the difference.

Look at the bottom. The color should be (note the qualifier "should") gold or yellow. This one isn't as absolute as the others, as I've eaten fully ripe watermelons that were still white on the bottom. Different breeds have different habits.

The problem comes in when you're picking one from the grocery store. The curlique got left behind when it was picked, it was probably picked at the same time as all the other melons without concern for peak ripeness, it's probably been bred for storage life rather than taste, etc. At that point, the thumping is the best option, but it takes practice to tell a ripe watermelon from unripe.
