TPS Potato Reveal #5 - SG Crosses

- IIt has been hard to wait until the skins set on this row of SG cross seedlings, because the monster plant that gave over 8 pounds of potato berries is one of them. With a plant of such large size, it was likely to have a huge yield of potatoes underneath it. You won't be dissapointed watching this potato reveal of true potato seed seedlings.
It is not unusual for seedling potato plants to have large variations in characteristics from each other, but it is unusual for one plant to so totally over-dominate the others in its same group that several of them essentially were shaded out and killled! That's what happened with this row of seedlings, there should have been 10 or 11 seedlings to dig, but in the end only three were worth collecting individually, and only about 7 produced a noticeable yield of tubers. So the variability in the different seedlings of this cross was incredible.
One change I have decided to make when I am evaluating my true potato seed plants is that instead of cutting up a smaller tuber to evaluate the seedling for flesh color and other characters, I will now be cutting up the LARGEST tuber the seedling produced. This is to check for the presence of hollow heart. Hollow heart is a physiological defect of potatoes that is caused primarily by uneven growth of the tuber. If growing conditions change, usually moisture conditions, the tuber can grow so quickly that it forms voids inside the tuber. These lead to rotting and poor storage ability of the tuber, and potatoes seem to be prone to hollow heart on my soil, so I am very focussed on selecting away from seedlings that have severe hollow heart in their seedling year.
I am also not concerned with the soil attached to the potatoes when the TPS seedlings are weighed for evaluating yield. Since the soil is more or less similar with all the seedlings, it doesn't truly impact the basic evaluation. The weight of the soil on the potatoes isn't enough to prevent the scale from giving me a good general idea of the total yield each potato has produced. Washing the potatoes actually negatively impacts their storage potential, so I don't want to compromise any that I decide to keep for planting next season. - Jak na to + styl
Great vid! I have a few TPS. I grew out some store bought potatoes just because they started growing. Threw them in pots and 4 out of 18 plants had berries.
Sorry for being so late to respond, but there is a good chance the hollow heart on your potatoes is caused by boron deficiency and can be corrected with a certain amount of laundry borax. For a soil with a TCEC of around 10meq/100g, this us around 10lb/acre.
Yes very interesting, thank you xD
3 years later... wow, you have a lot of rocks! :-D
Lmao
Like see video of potatoes from the tubers of each one
Hey just wanted to say, not sure if your aware but you seem to have some rocks there *nod* Since you brought up the rocks I was just thinking my Dad used to have an old potato picker that pulled behind his Model H John Deer tractor and would dig the dirt and potatoes out of the ground. sift out the soil and leave the potatoes on the top to pick. But the same thing would happen with the larger rocks if you can get your hands on something like that perhaps it would then be a fairly easy matter of using it to dig up the rocks plop them on top of the soil then come along and ....move them to a rock pile on the edge of the patch or something.
What a monster! Wow! Dammit that it had to have hollow heart.
But it has so many good features that it would make a good plant to cross it with something that has no tendency towarts hollow heart.
With its TPS from this year you can already get an idea how much hollow heart it passes on to the seedlings. And by crossing it with another good variety that percentage should drop even more :)
I cut the big ones off camera when I need them in the kitchen ;) small and big ones are all test food. I keep the medium sized tubers for planting, tubers with 4-6 eyes.
My scab problems have their root in the light soil structure not retaining water. This years lack of rain brought out the scab to a degree that I've never seen before. In a regular Swedish summer (= cool and rainy lol yay!) it's not quite that bad. But one of the long term goals is to establish a breeding line with scab resistance. The diploids from the Mayan series are promising. I'm going to be a busy bee next year lol will try to do some tetraploid x diploid crosses with them.
Yeah, it was too impressive in a bunch of ways to just toss completely. But I don't think I'm going to plant a huge row of it either. One thing, the huge berry yield makes me fairly certain it is a big producer of fertile pollen, because the TPS patch had fairly uneven bloom for most of the summer, I suspect that with such a heavy berry set, it must have been selfing a big percentage of the seeds. So it will be useful to have around just as a strong male parent variety.
I did eat these potatoes I did the test cuts on and they were a waxy potato. It would have gone way up in my book if it had been floury. I actually don't have any floury yellow tetraploids. I don't have a lot of desire for massive yields of hollow hearted waxy potatoes. But the genetic potential of this monster is pretty clear.
I can't wait to see your cross Torp. I watch your channel too
How long are your rows? You're growing a lot more plants than I do, I wish I had those possibilities. If it was me I'd just do two plants in lack of space ;) one planted early and another one some weeks later. That usually covers the season good enough to have pollen available for any cross.
Good starchy potatoes seem to be hard to breed. I also got tons of all purpose or waxy ones and quite a few which are in the rock hard category lol boil them in a stew for 2h and they still are firm... very useful too, but I'd like some good starchy ones. I think I got 2 so far from the TPS and both were immediate culls because of tiny yield and scab. Have you found any research papers regarding breeding for starch content? I wasn't lucky in finding much, so my breeding isn't very structured in that regard. Was crossing starchy x all purpose and got mostly all purpose and waxy. Which was kind of unexpected.
@@torptomaten3981 I haven't read anything on breeding for starch quality. There's got to be some information on that though. I think I'll ask on the OSSI breeding forum and see what pops up. Bill Whitson is a moderator on that one and he has read TONS of potato papers and usually has a list of them he can recommend. Sure beats searching for the right paper by yourself :)
I do have a couple of very starchy varieties from previous years. They aren't perfect, but I am keeping them till something better comes along.
I don't know Tim, the hollow heart seems to be rather minimal in Monster Vine compared to some of the others you've shown. For my money I'd keep it in the breeding program with all its other bonuses.
I will definitely keep a few at least. And Nathan is interested in some as well, so I'm not going to throw it away exactly, but I'm not sure I want to plant a bunch of these. I'm on the fence right now. I'll make more decisions once I have all the seedlings dug and assessed.
Hi, I think that a lot of us where waiting to see the results of that potato. I thought is was pretty with the amount, size and that most of the potatoes seemed to be around the base of the plant. Now in one of your other videos you mentioned that you had a unusual wet year and I read that Hollow Heart was mainly environmental. I'll be interested to see how they cooked up.
I was gonna say...can you cut the hollow heart out...and mash up the healthier parts of the spud?? :-)!!
Yes, potatoes with hollow heart are perfectly edible unless rotten, but the potatoes with the hollow heart will begin to decay quickly, they don't store well, and often will damage other potatoes in storage if they begin rotting. So its a really bad problem to have if you are planning on storing the potatoes.
Lovely video update. Thanks a lot for sharing! Liked and subscribed! By the way do you keep chickens also?
Yes we do, just a small homestead flock. There's a couple videos about them further back.
you have a lot of rocks
Fun reveal. Did monster have berries?
