Hi Everyone, I was wondering if there were charts for CPs showing what varieties there are and what you can end up producing if you mix certain types? Kind of like Plant A + Plant B = Plant C I was hoping there was something along the lines of this (one of my other hobbies is shrimp keeping)  I'm still very new to the CP game so I'm trying to learn how the different varieties originate. Thanks in advance for any info  |

That chart makes me want to get into the shrimp hobby! They look like Koi markings and varieties. I did see once see a Sarracenia A + B = C somewhere of natural hybrids. I will see if I can find it again.

I will see if I can find it again. Thank you and please let me know if you end up finding it! On a related note, are there "gradings" or "rankings" for quality available somewhere? The shrimp hobby is great! They're unusual and some varieties (cherry shrimp AKA neocaridina) are really easy to keep even in tap water. This chart is fairly outdated now and there are tons more variations out there! Don't want to go too off topic in the thread, but message me if you're interested in more info and I'd be happy to shoot some resources/contacts your way |

...hmmm, very interesting, but when it comes to crossing anything, isn't it like the great thinker and long distance runner Forrest Gump said, and I quote (partially)... "crossing is like a box of chocolates, you never know what you're gonna get". Isn't that the fun of it? All my compost surprise tomatoes come to mind. Just making conversation, nice shrimp graph. I don't think genetics are like math though, therefore cannot be arranged into neat formulas that guarantee results. Of course I have been wrong in the past! Cheerio!

Surprise results are always fun. I think you're quite right with the point that genetics aren't always that simple. Even with the shrimp, those are only the "best guesses" because the original parents may have originated from other crosses and are now carrying those (hidden) genes. I guess especially with plants where you're keeping a lot of them within the same enclosed space it can be hard to truly determine who crossed with who sometimes. How does one end up identifying the offspring then? Is it mostly the physical characteristics of the plant that determine its name as opposed to the parent plants? |

Well Sarracenia are easy, all their species all are capable of fertilising each other and the hybrids thereby formed, Daringtonia are a monotypic genus as are VFTs so can only be crossed with themselves.
Cheers

I've seen similar figures for plants before, but usually never quite so expanded. Often in ecology papers you will see the parents, the F1, and the segregating F2 (like here: www.frontiersin.org/files/Articles/57771/fpls-04-00321-HTML/image_m/fpls-04-00321-g004.jpg) but usually not beyond that one cross. The basic underlying principles behind genetics is math/probabilities and in breeding we depend on ratios to predict the chances of getting something desirable. Even with all the new DNA work and breeding algorithms coming out, we still have to look for ratios. For plants, it's a lot easier to recover 'hidden genes' because you can force a plant to self-pollinate. In shrimp and other animals, finding 'hidden genes' take a lot more work. Physical characteristics are used to identify offspring for ornamentals, and for crops you often supply genetic evidence too. I can't speak to CP specifically, but the general notion is that a cultivar must be clearly distinct and discernible from other cultivars. When you register a new cultivar, you typically have to grow it for multiple years across multiple sites alongside a check (a standard cultivar) and take very detailed notes to make sure the difference is consistent. This is one of the basic requirements for registering your plant with the governing body/authority (CFIA, ICPS, etc.) The formal latin name for a cross is usually Genus species x species 'Cultivar name.' If you cross between species or genera, that portion of the name can be a fusion between the two parental names. |

...as always, a very informative post, thank you Sokkos. I firmly believe though that at the end of the day Mother Nature is still the boss when it comes to these things, try as we might to decipher Her intricacies.

Whoa lots of good info here thank you for taking the time to explain! I've still got a ways to go before understanding all this stuff D: |
