Hybridizing in General. Picture Requests.
Comments (9)Wow - little berry! "Feeble calculations" - what wrong with them to call them "feeble"? There is always a chance that somebody would put us down - but why do it to yourself? You will get a bunch of new seedlings - and some of them will be red semidoubles with wavy leaves with red backs - because these genes are available. Why not all - because you do not know what is hiding in a recessive pool of genes combined with dominant genes. You do not know if ruffled leaves on Evergrace are double dominant or dominant with something else recessive. Tha's why you asked questions about parentage - if you would have all the genealogy - you would have better idea. My guess is - selfing is the answer - it will give you all combinations of recessive and dominant genes - and you will have Mendel laws in statistics. As far as I understand there are complex genes as well - that control not only flower type but leaf type - example - wasp comes with bustle leaves, etc, etc. Plus you can predict to some extent how your combinations will show themselves- but you do not know if it will be WOW or so-so. But to start with - we need strong vigorous symmetrically growing plants - and you have excellent parents to start. Waiting for the results Irina...See MoreBrugmansia - Datura Hybridization; Any Info?
Comments (15)Hybrids, Hmmmmmmm. I did some of that 30 years ago. We used Colchicine. I did a search on plant mutation chemical. My times have changed. Ever more toxic ways. Anyway I thought I would throw 3 cents in. Being a reborn plant newbie of less than 3 months my thoughts had drifted to our old reseach. I could make a new Brung and name it. I could name it after my wife and give it to her as a gift. To those of you who would like to toy with some hybrid work at home here is a little info. It is a pretty safe and easy method. Since chromosome segregation is driven by microtubules, colchicine is also used for inducing polyploidy in plant cells during cellular division by inhibiting chromosome segregation during meiosis; half the resulting gametes therefore contain no chromosomes, while the other half contain double the usual number of chromosomes (i.e., diploid instead of haploid as gametes usually are), and lead to embryos with double the usual number of chromosomes (i.e. tetraploid instead of diploid). While this would be fatal in animal cells, in plant cells it is not only usually well tolerated, but in fact frequently results in plants which are larger, hardier, faster growing, and in general more desirable than the normally diploid parents; for this reason, this type of genetic manipulation is frequent in breeding plants commercially. In addition, when such a tetraploid plant is crossed with a diploid plant, the triploid offspring will be sterile (which may be commercially useful in itself by requiring growers to buy seed from the supplier) but can often be induced to create a "seedless" fruit if pollinated (usually the triploid will also not produce pollen, therefore a diploid parent is needed to provide the pollen). This is the method used to create seedless watermelons, for instance. On the other hand, colchicine's ability to induce polyploidy can be exploited to render infertile hybrids fertile, as is done when breeding triticale from wheat and rye. Wheat is typically tetraploid and rye diploid, with the triploid hybrid infertile. Treatment with colchicine of triploid triticale gives fertile hexaploid triticale.

Comments (2)All members of the genus Malus can freely cross breed these Include : mountain ash, hawthorn, apples , flowering crab apples, and about 20 others. the edible quince,Japanese quince,pear ,Asian pear, apple, crab apple can all crossbreed . but the F1 are disappointing .all raspberries ,dewberries, loganberries, mulberries , wine berries, black caps, blackberries can crossbreed. As to the rest 1. Grayleaf raspberry (R. ideaus spp. strigosus) vs. European common raspberry (R. ideaus spp. ideaus)? 2. The various American blackberries vs. the various European blackberries and native/non-native forced hybrids? 3. The various native plums with Prunus domestica or P. tomentosa (I think I read that P. tomentosa (Nanking cherry) will freely hybridize with P. pumilla (sandcherry)? they have crossed the sand cherry with the plum in the 1970's 4. The various native crabapples with Malus domestica/pumilla? 5. American mountain ash with European or Asian pear, or the quinces, or at least with European mountain ash? Same for chokecherries since, I think I remember, that Pytina/Aronia can hybridize with Sorbus americana. 6. The various native plums with the man-made plum hybrids?Luther Burbank crossed Beach plums with domestic plums to give them Hardyness 7. "The native plums with peach/nectarine or almond? yes available" 8. The native mints and onions with the European garden species.You can cross onions with onions and onoins with garlic ( shallots) but you can not cross them with leeks. 9. The native silverberries with non-native Eleagnus spp. (Russian olive, Autumn olive, goumi). 10. The native honeysuckles (Lonicera spp.) with the increasingly popular blue honeyberry/haskap (Lonicera k... forgot). AND NATIVE VS NATIVE: 1. Forb/herbs like the Agastache spp. within themselves, the Monarda spp. within them selves, and so on. It seems that there are not many natural intermediaries between species in the same region - yet, maybe which mixing members of a genus that are regionally exclusive of each other, the likelihood for chance hybridization is greater? For instance, are the various Rhododendron spp. of a given area unlikely to hybridize with each other and same of the blueberries of a sub-region, yet when you plant Rhododendron spp. and, respectively, blueberries with their cousin species from opposite coasts, will hybridization occur more frequently? You can cross high bush Rhododendron with azaleas and Pjs I which that there were an online resource cataloging natural compatibilities within familiar horticulture genus. Purpose: I don't want to plant any foreign plant near my natives that would be cross-fertile. I would plant Prunus tomentosa if only it wouldn't supposedly readily hybridize with P. bessyi. Thanks, Now can you answer this one for me loquats can be grafted onto pear trees but can they crossbreed with pears ?...See MoreHybrid & Crosses ?
Comments (7)All crosses are hybrids. ...and this is about to get muddy here...nonetheless... This subject on whole is not technically defined as separate entities...but, an initial cross producing a hybrid may not (generally not) come true to type after the 1st generation. Usually the hybrid parents (if the cross is stable/predictable) will produce a singular-quality and stable plant. The continued hybrid parent cross will consistently produce a "true hybrid" who's traits you can count on...even if the seeds grown out from the saved seed of the next generation of the hybrid usually is not. A released cross, as is it preferred by most people's use even though technically and initially a hybrid, is stabilized and can be predictably seed-saved, and come true to type predictably most all of the time...basically being treated like open pollinated seed at this point. Even though the initial cross was a hybrid, selections over time from saved seed have stabilized the cross. That said, there is no standard on this. Someone can call something a cross, release it into the wild, and it's genetics may be all over the place. One rather recent pepper seed creator in particular (which I won't get into) is naming and releasing a lot of unstable crosses out into the wild...and years from now it's going to create quite a mess in the seed world if people keep his given names intact given the huge amount of variation these crosses are showing.
