Ok, so I know how to do tree breeding for different species. What i'm trying to do currently is something different. I'm crossbreeding a giant sequoia tree with apple oak trees so I can have a giant sequoia tree with increased growth rate. However, the saplings are just a bunch of hybrids with mixed traits. Is there a way to 'purify' saplings to give them exactly the traits that I want?
Do know that hybrids aren't bad at all when it comes to treebreeding, due to the fact that the active traits are the only ones being used to determine the tree characteristics when a sapling grows. All the saplings of the adult tree will be identical to the one you planted as well, as the crossbreeding only happens during pollination.
If you still want a purebred tree for whatever reason, there is a way, but you might have to work a bit for it (I did some work on a testmap, found that it is impossible to purebreed a 'faster' seqoia while retaining the 3x3 and largest trait while testing with pollen (The pollen is default stats of each tree, which poses a problem). Let me give it a shot.
First thing first. You want a Seqoia-Seqoia tree, none of this apple nonsense. So you have to understand the mechanics of how breeding works. Basically, when you breed a pair of trees, the resulting sapling will be one of four possible outcomes based on the trees you're breeding (that is if you only care about the species trait, of course). In the case of Seqoia and Apple Oak, you have: Seq+App, Seq+App, App+Seq, App+Seq (Take a look at
this for a more in-depth explanation). As you can see, breeding two purebred trees together will
always result in a hybrid of those two.
How to counteract this? Generational breeding! Just pick one of the hybrids generated by the Seqoia-AppleOak pairing and you should see that it will have the 'faster' trait in either active or inactive, as well as a jumble of other stats. Basically, every stat that differed on the two trees will be shuffled, as there's an equal chance of each trait getting the active state or not. You might find that your hybrid is an active small 1x1 faster growth seqoia, with inactive largest 3x3 slower growth apple oak, which is quite amusing when planted.
Your hybrid Seqoia looks good on paper, as it has the faster trait, but it also lost it's height and girth, so you'll want to breed that back in with a couple of default seqoias. just breed your hybrid sapling with a normal seqoia until you get a sapling with either pure(both inactive and active) 3x3 girth or largest height, whilst still retaining the 'faster' trait in either active or inactive state. Then replant and do the same until you have both height and girth back to default levels. Feel free to make this a pure Seq-Seq sapling as well. Remember though that you need the faster trait in either active or inactive, or you'd have to start over.
Next, you should do the same to your apple hybrid from the first batch. This is a bit more tricky, as you'd have to retain two traits, the girth and height, as either inactive or active instead of just the speed. Basically do the same thing as the seqoia until you have an apple-seqoia (It's important that you do not make this a pure apple sapling!) with faster-faster growth trait and either inactive or active largest and 3x3.
Now you have two saplings you can breed together to create your thorough-bred seqoia! Basically, just mash them together and you should after quite a while have a purebred Seqoia sapling with purebred 'faster', 3x3, 'largest' traits. Going by the square mentioned earlier, you should have a 50% chance of getting pure in each of the stats (t1-t2, t1-t2, t1-t1, t1-t1), multiply that with a grand total of four stats (Species, Speed, Height, Girth) and you have a lottery
You might want to do this in increments; get the pure stat in one or two at a time, replant and keep going for more sanity.
Ta-dah, you now have your awesome Seqoia sapling. But as I said earlier, a Seqoia-Apple Hybrid with active 'Fastest', '3x3', and 'Largest' will look identical to outsiders not sampling your saplings, and you get no discernible benefits other than a soothed OCD heart
.
TL;DR? Yeeah.... don't do this, man, it ain't worth it son! Just get one of the hybrids, then mash it together with a regular seqoia until you have all the traits you want in your tree in the active position. Seqoia-Apple is awesome and easy in that regards, as it has no recessive/dominant bs to worry about. Should take you max 1 hour from start to finish. I sincerely hopw you read this before you read all the other stuff, but hey, you asked for it
