Male vs female?

When you have 2 strains that you’d like to cross , what is the decision making process as to which to use as the mother and which to use as the father ?

I grew guerilla and indoor for 30 years , made 1000’s of seeds . My outdoor breeding experience was only to pick one of many patches and do an open pollination for the next years crop .

When growing indoor I never actually tried to make seed as I had access to all the latest and greatest clones . It was a revolving door of strains in and out keeping an occasional mother .

Getting back in the game on a much smaller level I’m trying to understand the criteria of picking a mother and father when making a cross of different strains .

Well, since they are different strains, I think we have to go by the most typical factors in both strains, such as vigor, lateral branching, ease of cloning, smell and trichomes, flower formation, etc
Or what is your goal—shortening the flowering time, trying to transfer the flavor from one to the other, among other factors. In the end, it’s you who will decide

I guess a better way to describe my question would be a scenario such as this …

You have 2 different IBL strains that are each genetically pure , no hidden recessive genes/alleles . All seeds grow basically as clones of each strain .

If you used a male of strain 1 to a female of strain 2 and vice versa of would the resulting seeds from both crosses have the same genetics ? Splitting hairs I guess but curious .

I was recently having a small discussion about this. I swear i read simewhere in DJS breeding book that he says and recommends using the male as parent as it usually influences/adds more to the breeding?? Again id have to reread and c if i can find that??

Ah, I think I get it. Keeping males is good for breeding because with one male, you can preserve the original and create several generations to find a good female. Then you can cross her with the original male to do a backcross to ‘strengthen’ the genes.
Regarding whether the male or female pass on different characteristics, I’m not sure. For example, in humans, the woman passes on our mitochondria. I need to study more about this.
Bodhi is a person who likes to work with males, like the 88G13HP and, if I’m not mistaken, the Lotus

Heres that paragraph from DJs book, not exactly what i remembered it reading but close to what i was thinking about!!

On a small scale I choose mostly on vigour and structure depending on what I’m doing. I might want to use the short male for example.

afaik males do not inherit the same as females from
a stable line, so i think it does make a difference :wink:

but …
only direct testing will bring in information relevant to the specific lines.
there is no way to cut around progeny tests, imvho. (not without a lab.
but then it is not ‘breeding’ anymore … it’s “engeneering”, lol :face_with_hand_over_mouth: )

Don’t overthink it, grow them out and choose what you think is the best boy regardless of strain and use that one to hit your favorite girls, IMO. Certain strains can dominate and it’s not so much dependent on sex in my experience. In most cases you’ll get mom learners, dad learners, and combos in between, so as long as you use two strains you like, you should be good!

I’m also super curious for opinions here; like if you have a kush and a haze you wanna experiment with … look for a boy haze and a girl kush? Look for a boy kush and a girl haze?

Simply look for the best overall male and let that drive decision? boys for structure, girls for flavor?

Super interesting topic I have no clue on.

There’s a debacco video on it, give it a watch.

https://youtu.be/8yilbFNjC2U He talks about genetics to pick for.

He also talks about using ethephon to reverse the males into creating female flowers. You can then grow out a bunch of males and pick the best male to breed with based on the desired male phenos that grow on it’s female flowers. (No you can’t smoke it)

Check out this video, pretty interesting on plant genetics and how they pass traits

That’s what Blue Star does.

Watched all these vids and they had great info about picking males; but nothing on OPs question:

If you want to cross two lines, which line should the male come from?

That really depends on you. These videos answer that question a little better.

Essentially you pick a male that has the traits you want your female to inherit. But it’s important to know the science behind how weed genetics work. For example that breeding overview shows a genetic tree and how to get a short and airy plant if wanted @5 mins.

then after you’ve decided what your goal with the breed is, you can find a male and female plant to try and get there. But keep in mind, Weed genetic, eg

Yes. In cannabis, some traits are influenced more strongly by maternal or paternal genetics due to how inheritance works:

Mitochondrial and chloroplast DNA (cytoplasmic inheritance): These are only passed down through the mother (seed parent). Traits tied to energy production, photosynthesis efficiency, and sometimes growth vigor are maternally inherited.

Sex-linked traits: Cannabis is a dioecious plant with XY sex chromosomes. The male (XY) can influence sex expression more strongly since the Y chromosome determines maleness. Female plants are XX, so males decide whether offspring have male or female potential.

Nuclear genetics (most traits): Characteristics like height, bud structure, terpene profile, cannabinoid production, and disease resistance are usually polygenic (controlled by many genes) and influenced by both parents. However, breeders often report that:

Mother (seed plant) tends to pass on structural traits (growth vigor, branching pattern, yield stability).

Father (pollen donor) often has more noticeable impact on aroma, resin production, and potency, though this varies.

Breeders often “lock in” a mother plant with desirable structural/growth traits, then select males carefully for potency, resin, or flavor influence.

This is 100% the shorthand I was looking for, TYVM!!!

Hi brother.
Don’t want to spoil things… But the thing is:
How do you know if your male is ‘the one’?

From my point of view and i am just a old dude. Testing over multiple mothers and then you’ll see what your male is capable of. The simple thing is to select your favorite one ofcourse :stuck_out_tongue:

Thanks, SV :metal::metal:

Usually when I pop regs I spend the ticket on sex testing, sometimes keep a male that looks good/feels strong/stands out. This year I put one stud outside outside/in the woods a bit. Some girls gonna get laid down by the fire shortly and also collecting pollen.

I don’t have breeder aspirations, but nice baseline info for when seedmaking presents itself is what I was after.
