AZETIDINE COMPOUNDS, THEIR PREPARATION, COMPOSITIONS CONTAINING THEM, METHOD OF PRODUCING F1 HYBRID SEED AND F1 HYBRID SEED THUS PREPARED Azetidine compounds of general formula or an acid addition salt thereof, wherein R represents a hydrogen atom or an acyl group; R1 to R6 are hydrogen, alkyl, aryl or other groups; and Z is a carboxyl group or a derivative thereof, have useful properties by rendering the anthers of plants sterile. By cross-pollination F1 hybrid seed may thus be prepared. The compounds may be prepared by hydrolysis/alcoholysis of the corresponding nitrile oompounds, which are also novel.
