Its true Alberto, My bosses treated all mutations like gold, kept them secret like spy documents & had no concerns about the environment, spreading problems, or anything else, only $$$$ mattered. They certainly weren't the only ones doing it. There were many & a number of other mutations were collected too. Josh is right, they never spread from one to another, only reproduction was successful. Although i understand what Jim says about chemicals or stress being the causes, which i explained my self, but I have to ask, if chemical damage & stress was the only cause, how did we reproduce several thousand super healthy plants, perfect replicas from cutting & they kept the trait for decades until this day ? What an interesting mistery.... Well thanks every one !
