Amitrole-tolerant Nicotiana debneyi calli were isolated by stepwise selection to increasing amounts of the herbicide. One resistant line was examined over a period of five years. High levels of amitrole tolerance were obtained (up to 10−3). This tolerance, at the callus level, was found to be stably maintained under selective as well as non-selective growing conditions. Calli derived from plants regenerated from the initial tolerant calli also exhibited the tolerant phenotype, although to a lesser extent, and the tolerance levels varied with growth media. The influence of amitrole on organogenesis was also followed. Sexual transmission of the resistance trait to F1 (sib) progeny does not seem to obey simple Mendelian rules. The genetic data do not support the possibility of cytoplasmic maternal inheritance. © 1985, Gustav Fischer Verlag, Stuttgart. All rights reserved.
