what do you mean by stable? Less hermie plants, less mutants, or more plants look alike. If your saying that a population is closer in appearance, that would be homozygos, which damn sure isn’t accomplished by F3/4. Have many lines at F3/4 and on, have a line ive worked for 20 years, it’s at F9. The F9 gen is t even close to the F3. Why did I keep going, i wanted to see for myself. Always small populations, I do t have the facilities to run 100s at a time. But I damn sure know what takes place using populations of 40 or less.
the largest breeders, the guys from the day, they didn’t offer beyond the F1 in most all there offerings. Talk with some of the guys that have been doing it for sometime, and see what they say about it.
no hate bro, just disagree is all:)
