nature selects though does it not ? ..................... hence the expression natural selectionyou havn't used common sense! breeding full stop is unnatural you select etc, you move it to your goals.. otherwise what is the point?

For certain things yes, but even then it's adaptive, it's still to suit the niche it's in.
but in a way selection is nature, only on fast forward , its selecting the strongest and best ................. just like nature does but only super fast
when you start mixing chemicals in to alter a plants sex ..................... thats not so natural ............... its a tool of course but i think really it should be discouraged were possible !
if you grow out allot of seed like i do, you quickly come to the conclusion that fem seeds have less vigour , less diversity of pheno's , and to add insult you injuring you still get males anyway lol
Is it always selection of the best? I don't think so myself. I could agree that natural selection selects the best for that given enviroment at that given time. again down to numbers, lets apply it to plants, lets say for years there was abundant water and no drought so a longer season for flowering and hence the late flowerers are preferred, then one season there is a drought suddenly the late flowerers are in, they'll be a shift in dynamics towards earlier flowering types.
They AREN'T males, A Y Chromosome just not just spring up by itself.. plants can and do have chemicals within them that do the very thing you are fearing. As to the last part I sprout plenty of seed I have seen no difference in vigour from F7 seedlots of M/F mating to F7 seedlots of F/F mating. Most of the fem seed out there are more than likely just S1's or even S2's of a cut they have, When it comes to fem seeds again there's reason for a lower variation rate, plant numbers!! just because some out there do not care and have abused the tech it does not make it the techs fault.
i see no harm in using a fem plant in breeding. selection is everything.
could any of the naysayers explain to me, what is the difference between using an outstanding female from fem seeds, and using an outstanding female from regular seeds in a cross? (to a male plant)
how will the progeny differ?

Natural selection is an unfortunate term to have got into the public consciousness. It's not that nature selects, it's what survives in a particular environment. Nature doesn't make a choice. Nor is what survives best, necessarily the fittest or best, merely the most suited for the environment. Also a species doesn't adapt to its environment over time, but the random mutations that create an advantage get passed on, and those that don't have those advantages pass on their genes less frequently. This is a very different situation than nature selecting the best plants. Man selects according to his tastes. His tastes may be beneficial or harmful to the potential of the species to survive and do well in competition with wild plants. All we can say is that when man selects, those genes that man has selected will be present in greater numbers in following generations. This is why seeds that are feminised naturally, ie with no use of chemicals to force them to show intersexed traits, are more likely to show intersexed traits in future generations than those who do require chemicals to show intersexed traits. If stressing a plant, a la Soma's method, is enough to get the trait to show, then the offspring is also likely to show the trait if stressed, and sometimes if not stressed. If the plants genes are so undesirable as to allow a female (genetically speaking) to talk walk and look like a male, this alone does not make it male, and certainly doesn't make it desirable as a parent for future generations. Males do not show in female only lines, only undesirable females. Other female only lines will be full of desirable females. To use a female in a breeding program should have 1 quality, to pass on desirable genes to the future generation. It doesn't matter how it was created, it matters what's going to be passed on. If that is the tendency to show the flowers of both sexes, its a bad one to use, if its the tendency to show only male flowers, its a terrible one to use, but if it requires chemicals to force it to show any male traits, then and only then, can the other traits be looked at when making the selection on whether to use it or not.

Ie, just maybe, you guys saying never to breed with hermies, are FULL OF SHIT! Quit trying to squeeze quantitative genetics inside of those narrow mendelian minds - it simply doesn't wash, sirs. -T
