Identifying phenotype males

[Treevly]

If dealing with a strain which produces strong phenotypes, are males as easy to identify as females? I'll give an example, but there could be a zillion examples. I have some Sunshine Daydream seeds. Apparently it can throw off Bubba Kush phenos and Appalachia phenos. Would the males of those phenos be as identifiable as the females? Likewise with many hybrids.
Thanks

So many variables, Bubba should be an easy one to spot with that compact structure and huge leaves. .

This is a very good question.

with blackdomina i could rely on the fact that the femel also had very dark leaves. whether this can also be transferred to the Appalachia phenotypes? the leaves of her should also be a tad darker. provided that the nutrient supply is adjusted as required.

Hopefully it will be an exciting thread.

I don’t have that much experience seeing different males, but I’d guess structure, leaf shape and maybe any smells from stem rub might be the most obvious characteristics?

Observe traits of each individual used in the cross and you should be able to find a male that’s leaning to your desired phenotype.

I would recommend finding multiple phenos of the desired type as you won’t know it’s actual inheritance until after popping the progeny.

I think such an idea of phenotypes is not really reliable for breeding. I'd look at the actual traits you're interested in, not draw conclusions on other unrelevant traits, like wanting a certain high and selecting a plant because it happens to have a similar leafshape as one parent with a desired high for example.
there is the concept of gene linkage, if different traits are caused by genes on the same chromosome you're more likely to see them in the same combination in the kids as in the parents, however there are 10 chromosomes which divide over the kids independently, and then you also have recombination within chromosomes, so you can't really depend on the kids always having the same combinations of certain traits as the parents.
i.e. I would not talk generally about 'bubba kush phenos' and 'appalachia phenos', however if you specify a certain trait you could say for example 'this plant smells more like bubba kush than appalachia'.
so plants can lean towards a parent on a certain trait, but that's no guarantee for other traits(if you work with some lines longer you might see trends/relations, but then you still cannot say it also applies to other strains/crosses, and you would likely still sometimes have plants that defy the rule, since linkage is just about having more of 1 combination than expected by random chance, not those traits/genes always going together no matter what)

in the case of males where many relevant traits are invisible, I think you just have to accept that you don't know, and won't know, so you're left with either trial-and-error, or you have to do progeny testing so you can see the hidden female traits in it's daughters. or you could use multiple males to one female to spread the risk(if you just do 1:1 mating and the male has bad hidden traits, all of the next generation is fucked, if you mix pollen from all males open pollination style, then only select on the female side, you'd avoid that risk. the downside is selection would be less effective since you have an unselected mystery father. or just work with reversed females so you can actually see what female traits the 'father' carries).

If it’a an inbred strain, and you only care about sativa or indica effect, then you can tell indica by shorter plant with huge leaves. I’ve noticed a strong correlation between leaf shape and effect. But for hybrids they usually start out with wideleaf, as indica traits seem dominant, but by the time they get to the top the leaves might get narrower. So you should assess the male based on the top leaves not bottom. Using a fat leaf male you are likely to get all offspring like that.

But with all males, as others have said, you can only guess as to what they’ll provide to offspring.
