| Does this almond looks like a plum x myrobalan hybrid or just like an almond? During the flowering season I pollinated my proprietary F1 nonpareil almond flowers with myrobalan plum pollen. After pollination, My question is, does it looks like a hybrid? Or is it the result of self-pollination |

| Well to stop self fertilization you must emasculate the flower, if you didn't chance of a cross are rare. Usually by the time they open they're pollinated. You must emasculate before the flower opens. |

| I pollinated them before the flowers had even opened, plus my almond is the only almond in my street. Thus the only pollen source was myrobalan plum pollen. |

| Cool, sounds like a good chance then! I myself remove the male parts before they open so not a chance of self pollination.Male parts are removed before any pollen can be formed. Remember peaches are just almonds that don't split open. So no peach trees either? I'm not sure why you would want to cross a plum with an almond, but I'm sure you have your reasons. I'm not sure what the leaves look like on almonds? I guess like a peach! |

| I wanted to create a very vigorous rootstock. I wanted to integrate the drought resistance, dwarfness, early fruit bearing and the adaptability to grow on sandy and weed infested soils (traits) from my proprietary almond; and the drought resistance, water logging tolerance, heat resistance, and the ability to propagate from cuttings traits from the myrobalan plum. My Elberta peach died two years ago, however, I do have a flavor top nectarine growing 10 feet apart, plus, my neighbor has more than 4 peaches growing on her backyard and many peaches and nectarines growing on her backyard.

| Here is what almond trees look like---this is my proprietrary almond. This is the mother of my peach x almond hybrids. |

| Looks exactly like my almond seedlings. All of them, and it looks nothing like any of my plum seedlings. The leaves look almost identical to your almond as well. You wont really know until it matures, and flowers, then fruit for a 100%. |
|
| The photo looks like an almond. I grow full size myrobian plums and they stay green all winter. They are highly vigorous and since they are seedlings I get yellow and red fleshed tasty cherry sized fruit. I can see why they are used for rootstock. If you can cross them with an almond that accepts almond grafts they will be extremely useful. |
|
| I wish almonds were more hardy to grow around here. The rootstocks are hardy, but that doesn't make the scion so. The new ones from the Ukraine seem to be hardy enough. All are on Lovell. Five of them. Not peach hybrids. Hardy to zone 5, but that has to be proven to me. |
|
| I remember my ukraine ones turned to peach rootstock when it hit -20, though fine down to around -15. |
|
| already heard about Krymsk 86 ? It ‘s a cross between Myrobolan x Peach with good benefits Best regards
both pic's = Krymsk 86 |

| I wanted to get a few Krymsk 86 this year for apricot rootstock, but it suddenly seems scarce in the non-commercial US nursery outlets. |
|
| I remember my ukraine ones turned to peach rootstock when it hit -20, though fine down to around -15. Yiles! Here in so called zone 6 it was -14 and -15 two nights in the last 50 years, so they should work here, I hope! I may try them at some point. I'm worried though as we are expected to get rather cold the next decade, so that sucks if it happens. I have no faith anybody knows what's going to happen. |

| Drew, Your wishes of a cold hardy almond might come true. Based on my observations, my F1 Nonpareil almond appears to be cold hardy; for the last seven days, temperatures have dropped to below freezing and so far it hasn't suffered from frost damage-- it hasn' t shed its leaves yet. |

| Here is one of my proprietary rootstocks that hasn't been affected by this week's frosts. It is a cross between Santa rosa plum (seed parent) x Krauter Vesuvious Myrobalan plum (pollen parent). |
|
| weatherman: I've got peaches that still have leaves and it's been 20 or below about 5 times. That doesn't prove anything about how frost or freeze tolerant the tree will be. Why don't you explain what precautions you are taking to avoid self pollination, inadvertent bee activity, or wind pollination when you are crossing things. You've talked about this many times with little to say that I've seen about avoiding those issues. |

| Fruitnut, True. How I created my peachmonds: I followed the same steps with my Peacharine---The Elberta peach was used as the seed parent---and with my almond seedling. |

| What I don't understand is, if my seedling is 100% almond and not 50 % percent almond, 50% Myrobalan plum; How did the almond flower which was pollinated by myrobalan plum pollen was able to produce a fruit? Aren't almonds supposed to be self-sterile? Especially nonpareil almond? |

| Oh...I forgot to tell you all, an Almond x Myrobalan Plum hybrid does exist. It is used as rootstock for plums, peaches, and nectarines in Spain. It is marketed as ROOTPAC R http://www.rootpac.com/en/rootstocks/rootpac-r and patented as ‘PAC 941’ United States Patent PP21556. |
|
| Almonds are partially self fertile. For cold hardiness they have to withstand -10 F temps or colder to grow here. nonpareil almond does usually need a pollinator, it also is not known to be cold hardy and is considered difficult to grow in my area. Hybrids sound interesting but the almonds are not very good. They will grow here though. As mentioned I have hopes the Ukraine types can make it here. Bounty, Nikita's Pride, Prima, Oracle, and Seaside. |
|
| Thanks weatherman, I appreciate your explanation. I might try a few controlled crosses probably of pluots. Something like Flavor Supreme by Flavor King. Good luck with your breeding efforts!! |
|
| I have not tried it with fruit trees just blackberries and raspberries. What I do is use a box cutter razor blade in hand, not in box cutter. You cut around the base of the closed flower. Practice tells you how much to cut to remove male parts. It opens the flower and leaves only the stigma. For collecting pollen: A small cap, film tube, pill bottle, etc to collect pollen. Even just paper. I have found using pollen from numerous flowers a much better method than just one flower. You can use a brush too, but make sure to use new brushes for each cross. An electric tooth brush works good at removing pollen for collection. Just touch it to the top of flower without any brush attached. Catch the pollen in the container. What to use for bagging? Various materials can be used. Some use floating row cover, others use tulle (bridal veil fabric), pieces of nylon stockings, sheer tricot or other lightweight fabric, or bridal favor bags. The latter work very well! Used by most tomato breeders. |

| Fruitnut, Thanks. Next year year, I will be crossing plums with cherries, Cherries with Apricots, and Peaches/Nectarines with apricots. Drew, |
|
| Paper is good too, I don't like it as you have to find some way to tie them off, you can't see the flower. The organza bags are ready to go, with ties and all, you can see the flower, and it allows more air flow than paper. Although paper is fine, it does breathe, I'm just lazy, and the bags are cheap.When fruit forms I take it off, but with paper, you're going to have to take it off to look, put it back etc. Too much work. Time is money. |
