Studies on the mutant breeding of high-yield gibberellins strain The protoplast of Gibberella fujikuroi m978 were treated by mutation breeding forhigh-yield gibberellins, LiCl mutation was better than DES mutation or UV irradiation ifsingle mutation, but any single mutation was worse than compound mutation by whichthe mutants were more overproducting and genetically stable.
