Abstract: The present invention relates to the art of agriculture. The method of sterilizing anthers of plants comprises treatment of the plants with a sterilizing agent in combination with a diluent during the period of the fifth and/or sixth stage of organogenesis. According to the invention, as the sterilizing agent use is made of derivatives of phosphoric acids of the general formula: ##STR1## wherein R is H, a C.sub.1 -C.sub.4 alkoxy, dimethylamine, wherein X is O, NH; B is H, a C.sub.1 -C.sub.4 alkyl, phenyl, D is H, CH.sub.3 ; A is a C.sub.1 -C.sub.4 alkyl, phenyl furyl; R' is OH, ONH.sub.4, OAlk(C.sub.1 -C.sub.4), phenyl; R.sup.2 is a C.sub.1 -C.sub.4 alkyl, NaNH.sub.4, NH.sub.3 Alk(C.sub.1 -C.sub.4), NH.sub.2 Alk.sub.2 (C.sub.1 -C.sub.4), or mixtures thereof. The method according to the present invention is useful in selection and seed production.
