TPS Tuber WEIGH-OFF with RECORD YIELDS !!

- This is a follow on video to our last potato reveal, in which the Sarpo Mira cross F2 seedling row was dug. It was clear that many of those seedlings were very high yielding, and likely to exceed the previous Oxbow Farm record for yield of a potato seedling grown from true potato seed (TPS). With the weather conditions being so wet for the second half of the summer and all the fall, the tubers were extremely muddy. They were laid out in the greenhouse to dry the mud and so as much soil could be removed as was practical before weighing the yield of each seedling.
It should be obvious from the video how variable potatoes can be even when descended from the same parent varieties. With all of these seedlings being tetraploids, the possibilities for recombining of traits is dramatically increased, so it is always exciting to dig and taste each new batch of seedlings. Some of the seedlings in this set gave us astoundingly high yields, just about pushing the maximum possible yield for a single potato plant, at nearly fourteen pounds of tubers from a single plant. That is probably the highest single plant yields we'll ever see, given that it takes a very long season potato to produce yields that high, and our growing season was approximately 3 weeks longer this fall than it normally is.
In terms of selection, more and more we are focusing on a spectrum of traits that need to be considered, beyond simply keeping the highest yielding seedlings. In the case of the biggest seedling in this weigh-off, the yield was mind-boggling (13 pounds 13 ounces!!!) but the tubers were extremely irregular and rough, as well as being unattractively colored and the largest tuber had severe hollow heart. An oddly shaped potato like this is unlikely to become shapely in the second year, in fact any tendency towards secondary growth is likely to increase. So it is not likely that the record breaker will have a place in the future, unless it is unusually delicious when we cook it and taste it.
The frequent presence of hollow heart in our potatoes has pushed us to focus on breeding away from varieties that show hollow heart as seedlings. There is a school of thought that the highest yielding seedlings are most prone to hollow heart and other growth defects like secondary growth and cracking. It is difficult to know exactly where to strike the balance between tuber yield and quality. With luck and persistence we will improve every year, and hopefully we can collaborate together with other potato enthusiasts to find great potatoes for small growers and gardeners. - Jak na to + styl
That was fun!!! So neat to see the insides, and more importantly to me, what you are looking for, what you see and how you judge things.
I know this isn't the point of the video, but your flannel shirt looks fresh asf ngl
Dude that variety with the pink inside looks awesome! have you saved enough to breed from in 2019? I love breeding new varieties from TPS I had to smash that like button and subscribe. Awesome watching that scale zoom round. You have to be pleased with that lot. :)
Unfortunately I had to drop that one due to failing the taste test. It had an incredibly bitter skin, to the point of making your mouth burn. It indicated that the solanine (alkaloid) levels were probably too high to eat safely, so I chucked it. Kind of a bummer since it was so high yielding and pretty, but thats how it goes.
@@oxbowfarm5803 That is a shame when that happens. Yes that was extremely high yielding from that the looks of it and looked super good quality. I hope you can breed another type that is just as good with out the bitterness. Fingers crossed for you.
@@oxbowfarm5803 I thought they got that chemical build-up from getting sunshine on them which means they're exposed and its defense for the plant but if they were underground and got that I'm confused could you please explain? I'm really trying to get into potatoes because it's something everybody in the family likes and I'm trying to help, basically we're poor.lol... Thank you so much for your help I love your videos! Have a wonderful day
@@speaklifegardenhomesteadpe8783 some potatoes naturally have glycoalcaloids that are too high to be eaten. Some have more than others. Above a certain level and they are not very safe to eat. Greening potatoes can also increase the solanine level, which is one single glycoalcaloid, but potatoes naturally have low levels of several different ones. When potato crosses are made, the genes get shuffled so you don't know for sure what the levels will be. You can make guesses based on the parents and crosses with most commercial potatoes will be safe, but some lines bring in genes from wild potatoes which have a higher chance of having unsafe levels.
I grew potatoes this year for the first time in my life. I got the seeds from Tractor Supply. I got yellow and red potatoes. I planted all my potatoes in straw in like a 15 to 20 foot area and added strong dirt and fertilizer as the year went on very sparingly cuz frankly and pork. I just harvested the past few days and my potatoes many of them look like the ones you shown where there a little bit of a regular or they have the pink spots it almost looks like my yellow and reds mixed but I don't even know how that's possible. I actually have one that is a yellow and a red potato but it's one potato. Do you allow your plants to flower? I saw people saying you should cut the flowers off so I did but I'm sure they were up for a while before I did that because I frankly don't know what I'm doing. LOL I didn't get a massive Harvest but the fact I got any Harvest at all surprise me and is very exciting! I would really like your advice on the type of potato that you're planting I saw grow more veg also doing that same potato strain with good luck and I don't know where to get it but I would really like to. feel free to email me to its livinginhocking@gmail.com
Did I understand this correctly - you got 10+ pound from a single seedling? That’s amazing!
There were several from this group that broke 10 pounds. It was a fun seed lot to grow. I am not actually sure I will be growing any of the highest yielding ones though. There is more to a good potato besides big yield.
Certainly. Adaptability to your region is one of them. It just blows my mind that I can’t get 2 pounds from a tuber seed, no matter how much I baby those potatoes. I will try growing TPS this summer, and if that fails- switching to sweet potatoes instead. Good luck to you! Keep those good videos coming, they are very inspiring!
At the end of the tasting video will you be letting us know which ones you're growing on?
I'll definitely be able to say which ones I'm going to drop. Keeping track of the keepers is starting to get a little insane. I almost need a potato filing system at this point.
I got major 'no scab envy' now lol they all look so healthy!
Sad some got hollow heart. Your weather must go through rapid changes that it's appearing in so many of your plants.
What percentage of huge yielding plants did you get in the Sarpo F2? It seems to be quite a lot of high production ones to me.
I'm looking forward to see how Sarpo Mira does for me next year. Even though I don't get blight too often yet, it seems good to plan ahead of climate change. Blight will come more often soon. Better to start breeding for all kinds of resistances, not just focusing on scab.
Hey Torp, I'm a little fuzzy on how many seedlings I had, some of them disappear by the end of the season you know? I would say it was somewhere from 15 - 20% of the F2 seedlings gave me yields of 2 kg or above with probably another 20% gave me yields between 1 and 2 kg. This year was kind of a freak weather year though, it went from hot and dry to hot and torrentially wet at the end of July. We had an extra 2.5 weeks or so of growing season at the end of the season, which I'm pretty sure drove up yields on the late season plants, and Sarpo Mira is a very long season plant from everything I've read. You probably will want to cross it with some of your earlier stuff to get seedlings that can mature reasonably early enough for you. Last year the F1 seedlings were very high yielding for me, but all my potato seedling yields were way lower than this year, but relatively speaking, the SM F1 crosses had many high yielding seedlings.
The disappearing seedlings don't count. I also start with more seedlings than I harvest, ~10% are early quitters.
That's an exceprional good percentage of high yielding seedlings in both generations. Nice!
Late varieties are just an issue when they are true short day tuberizers. But most modern day tetraploids seem to be fine with a long cultivation time. I can trick those by planting tubers with excessively long chits, like 20cm+. Makes for a 3 weeks head start. I just need to remember which varieties need an extra early wake up call lol.
Might chit one Sarpo in March already, pot it up in April in the greenhouse and it should hopefully flower with my earlier varieties.
Just fun to watch the scale needle! I liked the 3 and 8 varieties. Have you tasted them yet?
About half way through them Cathy.
Awesome! What zone are you growing in?
USDA zone 5a.
Doing my first trials this season. Very surprised by how large and robust the seedlings are after only 30 days. 🌱🐝
I love watching these videos but why is it you just want dry potatoes... The waxy potatoes are the best all round potato because they don't fall apart and for me, they even taste much better... The thing about dry potatoes is, they soak up all the liquid or butter like a sponge causing you to have to use so much more and for a cook, that is not good. but to each his own. Thanks for sharing your potato journey.
If you eat the ones with the hollow heart will it make you sick?
Not usually unless they have started to rot, the problem is that potatoes with hollow heart will usually start to rot quickly in storage and it isn't visible from the outside of the potato.
