Hi Li, my KXTRR cutting is doing great. I grafted it twice on strong root stock. I expect fruit next year! Did the seedlings survive that were inserted along the sides of the branch! I'm prepping a plant to try that technique. Brilliant! 👍
@xiaoli2142 8 күн бұрын
I am so glad to hear that the KXTRR is doing well in your garden. It has been around 17 days since the seedlings were grafted at the trellis top, but I still can't tell if they are for sure survived. None have new growth coming yet but they are still standing and still green. Being at the trellis top out in the open, they face a lot more challenges than the one grafted on short root stock and growing in more controllable area. I can see one of them were eaten by something I am not sure what; one of them was knock out of the hole by probably a lizard, but for the ones that are still standing, they look good and have a chance to eventually grow (I grafted more after the video so I still have around 7 standing). Also, it is not necessary to put the plastic bag on. It seems doing nothing but create more rotten opportunity. The ones that without the bags doing just as well, so I remove the bags in just 3 days.

You need to watch some more grafting videos… I’ve grafted 100’s of seedlings onto cactus 🌵… Whatever you attempt grafting … your scion needs to be touching the cambium layer … If the seedling roots can touch this layer it will grow … KVA sucks as a parent … Great effort but no cigar … I’m 77+ years old and have been hybridizing since 9 years old… You’ve learned a lot about Dragon 🐉 Fruit hybridizing … for you others interested I’d glance over Mendel’s Law of heredity… Hylocereus undatus x Hylocereus stenoptereus = KVA, CM, Bruni I crossed Connie Mayer (sister seedlings to KVA) x Guatemala #1 … If you’re interested in the outcome … watch … Kim Phan Dragon Fruit … KZbin videos … Don Burnett Watch her video on Connie Gee … meet the creator … happy hybridizing …

It’s so east to come up with a new hybrid … I wouldn’t have used Bruni as a parent … Too much time and effort wasted… the fruit will turn out on the small side and if you got a 17 brix consider yourself lucky … you need to have a hybridization goal in mind before you pollinate.

Yes. I agree with your analysis. This is just one of my short experiment. I did realize that the out come of this cross may not be ideal. My real cross experiment is between Kathie Von Arun and Tricia. I grew up 7 hybrids from that cross and it took me 4 years to complete.

Hi… I wish I’d known you before you used these two DF varieties in your hybridization experiment. I do have some past knowledge of these varieties… KVA can be sweet, but its fruit is on the small side and its fruit can be somewhat soft at a 20 brix. I knew Eckhard Meyer in Germany that hybridized KVA, CM, Bruni, etc back before 1990… That’s another long story … one hybrider to another … I had a cutting of Connie Mayer before he named it … I made a cross using CM x Guatemala #1… There used to be an Epiphyllum Nursery I Vista, Ca. who also knew Eckhard his name was Jerry Williams. Jerry grafted cuttings of KVA and CM onto Opuntia cactus pads at the time frame… Paul Thomson a well know DF hybridizer was good friends with Jerry Williams … being interested in DF Paul acquired cuttings from Jerry … Edgar Valdivia and Paul were good friends… well Paul took Edgar to Jerry’s Epi Nursery and I’m 90%+++ Edgar took the pollen from KVA back home and used that pollen to start his Asunta DF line (Asunta his mothers name fyi) … I used Connie Mayer as the mother plant to develop my line of DF hybrids … I don’t care for the Asunta Dragon Fruit… the fruit can be on the small soft side and the plant growth can be on the small side … and the Brix rarely reached 17… I can’t remember, but I think Edgar used Condor x KVA to hybridize the Asunta’s. If you go on KZbin and do a search: Kim Phan Dragon Fruit You can view some of the DF seedlings I hybridized using Connie Mayer x Guatemala #1…

Hi, Is there a way to know which dragonfruit is deploid and which one is triploid? Thanks.
@xiaoli2142 13 күн бұрын
To be 100% sure, you need to do chromosome analysis, which can actually count how many chromosomes in a cell, just like doing prenatal diagnosis in human. As far as I know from my reading, most of the dragon fruit plants such as Hylocereus undatus (eg. Vietnamese white), Hylocereus guatemalensis (eg.American Beauty, Condor), Hylocereus ocamponis (eg. Tricia) are diploid, while the yellow dragon fruits Selenicereus megalanthus are tetraploid. When you cross hybridizing diploid with tetraploid dragon fruits, the hybrids will be triploid because it is the only way they can be viable. It could produce a lot of aneuploid seeds but most of them are not viable. That is why the triploid seeds have very poor germination rate. If you google chromosome analysis of dragon fruit, you can find chromosome spreading analysis image of the dragon fruit chromosomes.

Seed buoyancy is affected by density, with fully developed seeds sinking and underdeveloped or damaged seeds floating. Air pockets in non-viable seeds and outer coatings that trap air can also cause seeds to float.

Actually, for these triploid seeds, even the sinking seeds had very low germination rate, about 3%, which is much lower than those of the normal dragon fruit seeds, so it seems all those seeds, even the sinking ones, are deficient in some way. But it is odd that so many of them already started to germinate inside the fruit. If I knew this be the case, I would save some of the germinated seeds and put them in some wet towel to see what they would develop into.

One question, which type of graft grow fastest? One guy on fb told me that whole stem grafts (with a couple of spikes) get new growths early (in about 2 week). While single node (V-graft) takes about 3 months to start growing. Is this true?
@xiaoli2142 15 күн бұрын
I have never tried V-graft, so I don't know how fast it can grow, but just for stem grafting, sometimes it goes fast and sometimes it goes slow. It all depends on the timing, during winter time, it will go quite slow, warmer weather, it will go faster. And it also depends on the quality of the scion and the root stock, how healthy they are. I have one stem graft that took almost 5 months to start to show growth.

@gofwkratos410 25 күн бұрын
I think the problem with organic soil is that as it gets broken down and used up by the plant, the roots at the bottom start to get crushed together and root bound. I noticed a decline on my dragon fruit too and the soil level got low on my pot so I top it off with more potting mix. It had roots shooting down from the top already so i buried those in the process and my plants started to recover. I noticed that some of your dragon fruit also have roots climbing down from their post so thats why they probably recover. Seems organic soil causes root problem and then the decline. So when you plant a new rooted cutting it will thrive because it has a lot of space to shoot out roots from the top of the pot. Thats why you see so many people starting to recommed "permanent" inorganic potting mix lol makes sense, no soil depletion. Sorry for long post, just an observation i had
@xiaoli2142 23 күн бұрын
Thank you for your thought. I agree that organic soil does break down over time and the soil level gets lower. I think that is the best situation to add more organic soil on the top without overflowing. Dragon fruits are shallow rooted plants. When you add more soil on the top, very soon, you can see new roots growing in the top soil layer. The recovery of the declined plant is not only relying on the air roots from the top but also new roots growing from the bottom . Using sandy soil is a good idea but it still needs time to verify its long-term effect. I am doing experiment to verify it too in the meanwhile.

@xiaoli2142 Ай бұрын
The genetic calculation does not specify RR x KVA or KVA x RR, meaning the hybrids produced by either crosses will have the same probability for the hybrid variety. Besides, there will be so many variation in each cross, it will be very difficult to compare the differences between the two crosses, so it will be a lot of work but hard to get conclusion.

In both cases, careful breeding involves selecting parents with specific genes to create new and interesting varieties, making the exploration of genetics an exciting process in both animals and plants. ❤ We're currently growing Wallace Ranches hybrid seedlings and plan to cross them with another variety.

Really fun to follow along! Can you comment on any issues you see with crossing KVM with RR when RR already had KVM genes?
@xiaoli2142 Ай бұрын
KVA is the mother of RR, so half of the chromosomes of RR are from KVA, so they are genetically very close to each other, which could trigger the self-sterile mechanism when you using the pollen from RR to pollinate KVA. I always wondering how the self-sterile occurs. As far as I understand from readings, that when pollen pollinate a flower, many tiny pollen tubes will form along the stem of the stigma to guide the germ cells travel to the ovary. When self-sterile occurs, the plant produces enzyme in the stigma stem to block the formation of pollen tubes from its own so that the pollen from itself will not reach the ovary, while pollen from other varieties will resist these enzymes so their germ cells will travel through their pollen tube to fertilize the flower. So, if RR inherited the pollen tube formation genes from TC instead of KVA, it will form TC type of pollen tubes instead of KVA pollen tubes, which will allow these pollen tube resist the enzyme from KVA so it won't block the pollen tube formation, therefore allowing it to complete the fertilization process. I am just guessing, I am not sure if it is the true mechanism.

@@codyj7769 I think it won't have much of a difference in either scenario. The chromosome segregation and recombination would be the same but I can't rule out the influences of the mitochondrial DNA and the proteins that are involved in this process. I tried to do an experiment just like this, to use pollen from Bruni to pollinate Sin Espanis and vice versa, then I realize that there will be so many variations in each cross, it will be very difficult to compare the results from the two scenarios, so I kind of abandoned the experiment.

The pollen was air dried over the counter at room temperature for 24 hours before freezing. It is easy enough and good enough for pollinate of dragon fruit flowers from the same growing season. To pollinate the flowers from next growing season, I have tried to freeze the pollen with silica gel pack, hopping that the silica can continue to dry the pollen further to preserve its activity, but I have tried twice. None of them worked yet so far. The method still need some improvement. Do you have a specific way to dry your pollen?
