Odd question. Has anybody ever tried to make a male plant grow a few female flowers?
I don't think this is an odd question. I'm sure people have tried; I don't know of any technique that works to do this.
Apparently the phenomenon can happen in nature where phenotypically male plants put out rare pistillate (female) flowers, but its exceptionally rare. I vaguely remember DJ short claiming that the offspring of these plants tend to be unusually potent, or something to that effect.
Say you had one seed of a epic strain that no longer existed and it turned out to be male.
If you have a ceed, obviously the strain isn't entirely extinct, but the point is good.
Because of the way genetics assort randomly, tf the plant in question were a hybrid, it may be really hard to exactly reproduce this "epic" plant even if you had both male and female beans to start with. This sort of thing explains why its so hard to reproduce "clone only" strains into good ceed form.
If the epic ceed were from a landrace or other inbred line, you might be able to recreate ceeds reasonably close to the original by crossing pollen from your male plant with a somewhat similar (but different) female plant, then repeatedly backcrossing female offspring with the epic male. IMO, this is the best "legitimate" use for the technique known as "cubing" (which is a triple backcross).
Could you some how hermie this plant a get regular seeds to continue the line. Say take a clone so you have two plants of the same male. can you then hermie the clone and bang it with its father for seeds? Set aside any genetics defects caused by the process.
Again, given sufficient technology, I wouldn't say its impossible, but I don't know anyone who has done this, and I don't know of any technique that works to do it.
I'm pretty sure this could be done using fairly sophisticated subcellular chromosomal techniques, but this is highly specialized and expensive research lab stuff, not something for home, or even commercial growers.
