I have not had much luck stressing male clones to make them turn female, if you look up the Safety data sheet it does not sound dangerous.
Remember most of the ethephon will rapidly convert to Ethylene...
And as far as I know Ethylene in the amounts we are talking about in a dried mature Cannabis flower will be unimportant.

Im not sure esbe, reversing a plant by classic ambiental factors (extreme photoperiod variation, extreme topping or shocking, lack of NPK ...) doesnt produce enought flowers of the opposite sex to properly judge it. You need to heavily modify its ethylene hormonal state to produce an almost complete sex reversal using substances like STS and others.

If the stressed plant by classic ambiental factors easily hermies, then is not a desirable plant to breed with, at least for sinsemilla ganja breeding.

I guess I need to try this and test the results, I am thinking everyone has problems deciding what is a keeper male? You could make numerous crosses with known female clones and grow out the progeny of each but it is a lot of work taking a lot of time and space and requiring a lot of plants and most growers just do not do it.
I am thinking that if you transform your male clones to Female, smoke them you will get a good idea what genes the male has to pass on to progeny, you still need to do progeny testing but you could whittle down the numbers of males you need to progeny test in the first place. Just turn the males female and start with the best to do progeny testing...
I suspect the genes responsible for a plant with high THC, none of the wrong Cannabinoids, as well as the right terpenoids, will express in a female that was made from a male, and no more trying to guess or smoking real males to try and make an educated guess...
To me it seems like it should work.
I have read that the males transformed to female have a high incidence of sterility and have trouble making seeds, but that is unimportant if you just want to judge your male to determine it's suitability for breedin with your elite female clones. If anyone is still using real males to make seeds that are male and female anymore...

i will look much forward to that project sam! hope that others join up or already have experiences with the method that they want to share with us

Yes test test test. This is something i could really put my time into. It a worthy field.
If all goes to plan this thread would be marked as THE point in time that a massive jump in the evolution of breeding was made.
Serously gone are the days of hit and miss when selecting males when the term selecting didnt have as deep a meaning as this.
This idea of stacking the genes is fcking awsome. Its pretty exciting even typing out this post.
When you think about it... Its like compound interest... The rewards will be massive.
When you select the best males with the traits you want from this method really your not selecting male traits at all, rather female traits to match the selected female. The genes are stacked efectivly doubeling the frequency and in the next gen it will be x4. then x8 then x16 when with regular breeding it would be x2 x4 x8
This is seriously a huge idea sams

I thought it was valuable so I mentioned it, shame I didn't think of it 10 years ago before all the seed breeders stopped using males and now mostly seem to use STS transformed females as males for pollen, as all female seeds sell for more...
Anyway it should be tried as it allows you to express all the normally female traits in a male (by transforming to female) and judge it for qualities that are concealed in males. Then decide if you want to use the male for breeding or not. Seems almost to good to be true. I will try it as soon as I get some ethephon, maybe next week.

i was going to make a thread on this, but i thought it would be laughed at...silly me

what would happen if you dusted the males calaxes with polen from your reverced female....??????????????

will it be sterile???

i emagine ......if you seed it with another male... you get male seeds????

[Sam_Skunkman]

Try it.

It is to good to be true... but its still true.
I have been thinking a lot about genes the last few weeks and its strange but i had a feeling that something important was going to come from it.

It doesnt really matter about the competition from female seeds. Like all the breaders are doing it now to "complement" their lines lol. Let them use the mothods they like but this idea will allow people to produce uber potent varieties in half the time.

To me the reality of this idea is; the most potent variety in 100 years from now can be had in 50 years. I look at most things in life purely from a mathematical point of view. This view is sweeeet

yip, keep the fun level high!

though im not so shure we will end up with much better cannabis than is grown now or before

cant be true no one never worked this thing before?
