Mostly estaminate offspring?

[Random00]

Hello everybody:

From a breeding point of view, what would be the possible reasons of getting a mostly male (staminate) population from seed?

I hope the expert breeders who drop by this forums can put some light on this consistent fact which I have tested from certain seed company. One by one, the different varieties/strains from this company have given similar results. I mean ratios of one pistilate individual from six sprouted seeds, two from six, three from nine, or zero from four.

I understand selecting for pistilate tendencies, but is it possible that the breeding programs include selecting for male tendencies? Or, more exactly, could this staminate tendency be a consecuence of selecting for the preservation of other traits?

Thanks in advance,
Random

i think its pretty much 50/50 ratio once a resonable amout of seed are grown. ive had lots of females, and lots of males in different batches.

ive read that enviorment can effect the M/F ratio, but havent experienced it over time.

Hello, Pike:

Every test included a batch of seeds from a different seed company each time as control population, which were grown in the same environment and under identical conditions of selective pressure, and these perfomed well or very well in terms of pistilate/staminate ratio. I.e.: 60% pistilate or 80% pistilate.

All the seeds tested, coming from the mostly staminate producing seed company or the other seed companies, were regular grade.

Any ideas about the breeding reasons which can explain these cases of mostly staminate outcome?

Hi all

Among populations of cannabis, pheromones may influence sexual orientation.

Likewise, certain strains of cannabis are barometric; dictation in gender may thus reflect climatic and/or atmospheric pressures/influences upon a given population, at a given time.

Nature inevitably courses the ebb-and-flow of population density.

hope this helps

I've heard of breeders that would breed for certain characteristics (yield,potency)and unknowingly during their program they were also carrying along the genetic makeup that causes hermaphrodites, so they were selectively breeding hermies. I also know that certain landraces (thai genetics) or pure breeding strains that are more prone to hermaphrodite.
My experiment with propogating seeds is not to extensive.
I find that cooler temperatures with sativa dominant genetics tend to result in higher females.
I am still not convinced by "feminized" seeds. Nature will find a way. Jah.

Thanks for dropping by, DocLeaf and Brastaman:

I think we are reaching an interesting point by this way. Maybe they don't apply selective pressures to detect and remove monoecious plants from the breeding stock, so it's simply about doing a deficient job? Possibly.

However, it's hard to believe such a consistency in the (undesirable) results. Even leaving the parents selection at random for monoecy, the results should be more mixed, less uniformly staminate. Or not?
