- Buy Organic Seeds here! www.seedsnow.com/?rfsn=370843... Tomatoes, Aubergines, Peppers and Potatoes are all vegetables that can easily be crossed and then stabilized into new varieties. Plant breeding is important in our organic garden and can make all the difference if you wish to have disease resistance to specific pests common in your local area. You can also breed for uniqueness taste and other desired traits. Eggplants for instance are easy to cross and once done a new variety could be made available after only a few generations. Potatoes are probably one of the fastest to make stable as once the cross was made saving seeds from the tubers makes an instant new variety as will be explained in the video!

David, I am going to try to cross our beef steak tomatoes with our Chocolate Cherry Tomatoes. Am I correct in saying it doesn't matter if I pollinate the CC Tomatoes to the Beef Steak tomato or visa versa? If it works I then take the seeds from the new tomato to plant ...correct?
About your potato seed pod, did that grow from the flower on the top of the potatoes plant (not a daft question I hope)? At what point do I pick off that pod? Are you making another in-depth video about the potato pod-seed-planting steps etc.?
Thank you kindly.

Hi Roger sorry for the late reply your comment went to spam and I can't check that folder for every video. RUclips does not tell us either.
You can do the cross both ways as it will matter very little which way you do it crossing tomatoes. Once you have a tomato growing the seeds will be the cross known as a f1 first generation. Pay close attention to what traits are showing once plants are starting to grow and as the fruit develops as usually the dominant traits will show only in the first generation.
In the second generation you will roughly get 25% double recessive, 25% recessive & dominant (this translates to the dominant trait showing only) 25% dominant & recessive (the other way around, again this translates to the dominant trait showing only) and 25% double dominant. Both double dominant and double recessive traits are stable. That then means you should have 75% dominance showing across all the different traits you catalog from the seed of the f2 second generation. Dominance where it exists wins over the recessive trait. Also stabilizing a double recessive trait is easy as it will be quite obvious that it is recessive by the fact that it will only show at roughly 25% probability. Finding the double dominant in the mix is harder because you also have the 50% recessive & dominant variations, which show up as only dominant.
At this stage (f3) by planting out your 1-6 chosen plants (with the traits you are after) you can plant each one separately in rows having at least 16 - 20 plants, so you can evaluate the % of dominance or recessive traits showing up. Another way of saying it is, if one of your lines has all white fruit or let's say all pink flowers (the trait you are going after), then that trait is 100% either double dominant or double recessive and therefore stable. You will have stabilized that trait and you can move onto other traits in following generations. Note that you can stabilize several traits in one generation if you are lucky. Hope that made sense as I had a busy day and fit for bed now. Let me know if you have any questions.
p.s your potato seed will be inside the soft ripe fruit at the top of the plant that resembles a green tomato. There are no daft questions only stupid people giving us a hard time for asking.
@@workwithnature Wow! So much good information!
I would add that the direction of the cross is important and the male and female should be noted. While the pollen is carrying only half of the DNA of the father plant, the ovarium usually has extra DNA in plastids and chromosomes that can change some traits.
Such an amazing teacher and series of videos! Thank you!
Thanks David, wonderful video, very informative. We will try your method of cross pollination for our tomatoes. Sounds like loads of fun to watch for the results. It has been a very cold spring here in Nova Scotia so gardens are a month late. Thank you for the education. I have subscribed, don't want to miss a thing. :-).
Darlene
Thank you very much for teaching me pollination of all you vegetarian Plants
Thank you for this instructional video. I'm going to try this next year.
Thank you for the upload! Great information, now get to the choppa! ✌️
I have 7 kinds of peppers and that was so great. I will try it to see what happens. Great video.
thank you for sharing that infos on cross-pollination...keep vlogging..
love the scientific approach and discourse, and the accent. Nice video mane
Informative and easy to find. Thank you for the video.
this so helpful and hard to find. thank you!!!!
thanks for taking the time to make these videos
This topic very interesting
Very good video.
I work with tomato breeding in Brazil, but I do it differently. I extract just a little bit of pollen with a tweezer from a donor flower, and put it carefully on the stigma of another flower, then I repeat the process using the same donor flower again and again until it is out of pollen. This way I can polinate about 10 stigmas using just one donor flower. Otherwise I would need to have several donor plants in order to use each donor flower for each stigma as you did.
I had never seen pepper polination before, very interesting.
Very helpful, thanks!
Thanks for sharing your valuable information .
Work With Nature Nicely done.
thank you for sharing this videos
Excellent channel thanks so much just starting some breeding myself :)
Terrific, exactly the information I was looking for, thank you! Question: can I save the seed from the new developed hybrid or will it revert?
Thanks for the great video!!!
Thank you! I've got some accidental hybrids that I want to maintain and I'm going to try all of these techniques. Question: I noticed you're using wax bags; can I use thin clear plastic instead?
this is right on time! very informative bec I am growing my vegies for the ist time!
btw youare also handsome🤗😊
Something new to put in my to do list.👍
Thank you, it's so useful
Really interesting presentation Sir. It is pretty amazing looking at God's Creation. You have a great knowledge, and I am glad you are sharing it.
Great info! Thanks
Hello! Amazing videos, thank you very much. Do you have any video on how to stabilize a variety after a crossing?
Very Interesting and Useful!
Thank-you.
So thank you
Beautifully well done. Liked, shared and subscribed.
Hey i have a question how can i cross breed my tomatoes to be diffrent coluors. im not sure if it is possible just asking
for the potato seeds produced by the flower, at what stage are they ready to be planted and how are they prepared for planting
Thanks very much. I learned a lot!
Very good, thank you. I'm not to a point I want to try breeding yet but I like to know how it's done. I had intended to try growing potatoes from my seed this year but too many things happened. Had to cut out several things I wanted to do.
Hey,great demonstration but kindly how do i do the pollination of potatoes and find brand new tuber varieties? Do you mean that when pollination is done via flowers,tubers will be new varieties of both combinations.
Brilliant !
Would it be complicated to do the same kind of hybridation with strawberry?
David thank you for the wonderful information. Just a minor hiccup. Next time focus and zoom the camera closer to the subject.
Is it just trial and error which benefits you get from the cross?
So interesting 💚
thanks sir this is useful
Your tweezers look tailor-made for the job. Would you please provide a link for where to buy one? Many thanks!
Hello I have two cucumber plants that are parthenocarpic and have only female flowers. How can I hybridize these?
good information
Instead opening the flowers, can I take a small painter brush and pass it one one flower and the other??
Muito bom!
Aqui em Manaus-AM o clima é quente e úmido, então qual é o melhor horário para fazer o cruzamento ?
thanks
sir kindly tell that if you cross the same plant flower then obviously their characters are same then how new veriety can build up by same plant ???
I am going to practice with my tomatoes and see what happens. I just planted some, so it should be interesting.
Hey Mary, I am going to try this too. How did your work out?
Thanks my friends
From yemen
Really nice to know
I'm going to totally make some mad strong peppers
which variety is the best you think
This is a guide for me. I would like to try on how to cross breed plants
COOOOOOOOOOLLLL!!!!!!!
Are you able to cross Bell Peppers and tomaatoes? What would happen?
can be done with strawberries??
thanks for this video i learned and i wrote notes you encourage me into cross breading plants
By the way, nice trombone shot (or "Vertigo effect") at 1:04. It may be unintentional, but definitely a good one.
:)
Thanks :)
It was kinda easy enough, with the camera that i'm using. All automatic, I only found out how to do it that day ;)
Thanks for the feed back hey.
i dont know if you are still active on comments here, but can i cross a black nightshade with a tomato?
please we can mix pepper flower with tomato flower yes or no ?
Can you do this with fruit trees?
Thank You for the lesson David. Could You arrange a video about pepper crossing specifically? Thank You.
Will do.
Thanks for the feedback hey.
very good
thank you
welcome :)
I have a lot of colorado beetles too ... i just squeeze them between my fingers or they will eat all my potato's. Great video as always :-)
Hey how are you,
Thanks :)
I got a lot of them because the potato field had them next doors.
Now that there is nothing for them to eat they are mad at eating my eggplants. There is a fungi Beauveria bassiana one can use that seams to work really well.
Work With Nature Collect C beetles in a bottle/jar full of water, leave them in for a couple of days, needless to say water smells awful but is very effective, i sprayed potato plants and C beetles completely disappeared
Nature is really Beautiful once we understand tnq friend for the video if anyone holding camera for them also tnq :)
Is there any chances that for a cross breed chilli and tomatoes?
Does their seeds could germinate?
Whether anything was used on the stage before the flowers arrived
I agree
Thanks sir .... From India
You are welcome.
sir , we also want to see the result of your pollination of tomato ... kindly make a video on that new varity of tomato...thanks..
Good
this is the first time I have true seeds from my potatoes is there anything special I have to do to save the seeds for next year? love these vids thank you so much
Hi Jerry,
I would just ferment them like tomatoes. But you can also just stick them onto newspaper. Will work just as well. Take them out of the fruit first and place the seeds on the paper. When they are dry, put them into a glass jar with a lid. Sow them in modules next March and plant out when they are bigger.
David.
Do they lose any nutritional value?
Will potato seeds germinate?
I have completed Industrial Microbiology Imb
Thanks sir
Taya hang t
how do you do it in a small place
Thanks this was a great video. Can anyone help with knowing how to tell if the cross is successful before planting out the seed? I would like to know at what stage the anthers begin shedding polen and when it is too late to cross.
Obviously hybrids grown for commerical fruit or seed selling can be postive the cross has worked. I tend to cross earlier to ensure the fruit is hybridised but it is much more difficult with a lower fruit/flower survival rate. Thanks
Usually you will know that you have a cross because you did the cross yourself and have isolated the flower on the parent plant. Also you will have gotten rid of the pollen from the parent plant before it becomes mature. If in doubt you will have to plant out the seeds of the next generation and you will see differences in the plants traits. The anthers as mentioned in the video release their pollen once the flower on the tomato opens. Using seeds of a f1 hybrid as your starting population for your region is a smart way to make a new stable variety. But using shop bought commercial seeds that you got out of a vegetable may not be suitable as it may have been grown in a different climate to yours.
@@workwithnature thanks for your information and quick reply. So just to clarify as long as the petals are not fully open it will not be dropping pollen? Sorry i just had another source saying that it can even be too late once the flowers begins to turn a brighter yellow, thus attracting inects because the anthers are active
Sure no prob. What I am saying is you need to remove the flowers to be pollinated with the anthers and all, minus the stigma, at the stage when you see them at a yellow but closed stage, to insure the stigma is fertile, but no pollen has had a chance to drop on the stigma. To get pollen from the other parent you have selected, as part of the cross, you need to select a flower that is fully open. This flower has to be bagged to avoid accidental pollen from bees, that can add it to the anthers. Otherwise there is a small chance that the other pollen may tunnel down first. The female flower does not usually need to be bagged after you have hand pollinated, as it is not attractive to bees anymore. Different flowers on different vegetables will have different mechanisms.
And yes pollen does not drop when the flowers are still closed even if they are yellow. It is very easy to check that as you can try it with a flower to see. This is the best way in plant breeding is to look at what your plants are doing.
thanks you have been very helpful
I have a bucket of soapy water and put the potato bugs in that...I`m also having success with Neem Oil.
Question...how do you know which potatoes to cross and why don`t all my potato plants have seeds? We have a real pollinator problem in Ontario Canada. My Pollinators are wasps, Parasitic wasps, a pair of bumble bees, flies and ants...no honey bees!!!!
Hey good tips :)
As for the potatoes, that is probably to do with them being of the type that is diploid and not tetraploid. Diploid potatoes are self incompatible. Meaning they can not self fertilize. They need pollinators to do it for them or rather pollen from another potatoe. Tetraploid is far more common and does a very good job at self fertilization. Providing a bee shakes the pollen lose. Diploid potatoes are a good thing, you can use them for crossing too. Also as they are more rare, it is worth hanging on to them. You can cross diploids with tetraploids also. So to see if they are deploid check for a pointy fruit, then you will know for sure.
You can try crossing as mad as you like, so as many different types of plants as you can get. You will see the tubers the following autum and you can then select from the ones that taste the best and look acording to how you like them. Don't be suprised if they will be small in the first year, they will get bigger the following year.
Some of my tomatoes are still unfertilized flowers. I am guessing I might need to lend them a hand soon if they don't pollinate. Would that be your thought too?
Other tomatoes are already thumb-thick green fruits.
From the Canadian prairies...
Thanks for the video! Really nicely done.
Hey no problem Berny :)
Is It indoors or outdoors, that you have the tomatoes?
Have you tryed tapping the base of the tomatoe plants. This shakes lose the pollen. Try it when flowers open on your plants.
Work With Nature Outdoors. Urban backyard. Not a great amount of sunlight. They are raised beds above gravel... Doing the best with what I have to work with...
After watching your video yesterday I did, indeed, give the slow one a little shake. Can't recall if it was your video or a video recommended after yours finished that pointed out that tip.
Thanks for the response!
can anyone suggest me a university which offers plant breeding(around the world) for MSc? please

What is the best day time to do this, collecting pollen and cross breeding.
Tanveer Inayat I haven’t found a best time myself, but I tend to do it during morning before bees get to pollinating the flowers. You don’t have to do it then, though, you could just put a small bag on the flower like in the video until the time is right for you.
I did the same with my 2 pumpkin plants . I don't know if its same variety or different. Let's see what happened.
You will know if a fruit grows.
So let’s say I want to make a yellow Centiflor from sun gold and a red Centiflor which plant would take the role of the mother (the one to pollinate and host the tomato/seeds) and which would take the role of “father” and donate his pollen?
Either one it does not matter.
Okay cool, because I know with roses you have to breed them a specific way to get certain characteristics, colors, smells, benefits and such. I thought maybe it might matter with tomatoes too.
@@alexar.h.5031 You are crossing two tomatoes from the same variety. Even when crossing within species, in most cases the first generation after the cross, will show all the dominant traits only. After that in the second generation, every separate trait will show both dominance and recessiveness in all subsequent generations, till you have stabilized all the traits. So working in generation two you might stabilize fruit color, in generation three it might be fruit shape, leaf shape etc.
Thank you! Sounds like tomatoes are going to be easier/more fun to experiment with
Can I cross breed a tomato with a pepper?
I AM HUMAN no
I want learn agriculture
Im so tired of this ive tried crossing peppers and they dont make enough pollen
Check them at different times of day for your climate and then try.
Thanks a lot sir.please want to learn. More stap by stap
Will put up a video in the next week or so on how to stabilize plants once the cross has been done.
