I have read when one must back-cross 3 to 4 times to achieve a true strain ? need information about - to help understand Guess breeding is the next level
Its called bottle necking ... say you start with a bunch of different phenos.. in nature it could be a earthquake or flood that kills off the undesirables... or through human intervention you control the genetics to your liking. Usually by 3 you have a pretty tight cross. I have seen people bang plants a first time and get tight genetics though.I have read when one must back-cross 3 to 4 times to achieve a true strain ? need information about - to help understand Guess breeding is the next level
Really good description man. Obviously the selection aspect made sense but I never fully got what people meant by back crossing and always assumed when breeding the plants out you would select a male and female from the second generation that had the desired traits and then from the third generation and so on. This is obviously a much more practical way to get the exact traits you want.Backcrossing should result in the offspring having a higher frequency of the desired genes, each successive bx increasing that frequency. So you have your rad plant that is a super awesome pheno. That gets a normal cross to another plant, giving you a 50/50 split of genes in theory. From those offspring you find the one that has the traits closest to your original rad plant and then cross back to the original. Grow out those, select plants, cross back to parent and so on. Each generation of seeds should result in plants closer to the original.
Hope that helps.

I use "streign" to seperate from pathogenic reference of "Strain" another hot debate for decades.Cringe...... "Strain"

So you need to back cross(breed) it at least 3x's to obtain a "pure" lance - thought it was more than 3x's ? thanksThank you.
What ways can I reverse the train to get some pollen? There's always banana pre flowers but they're never fertile.
Thank you.

use breeded seeds (1) to female then breed seed(2) to female then breedseed (3) THEN FEMALE IS PURE ? (3 BACK CROSSES) DO i HAVE ANY IDEAwhen I backcrossed my GDP male it took 3 rounds to get all phenos stabilized and the fourth pushed all phenos to the GDP side. there was an round of inbreeding in between
