Abstract:
A method of producing transgenic seed or transgenic progeny plants which have resistance to glyphosate, said method comprising:(i) applying said glyphosate to a population of plants, at least some of said plants being heterozygous (Rr) for the glyphosate resistance transgene, said applying being at an advanced vegetative state before flowering, wherein the glyphosate effectively eliminates the viability of the male gametes which do not carry the glyphosate resistant gene (R), wherein the surviving male gametes which are capable of fertilizing female gametes carry the glyphosate resistance transgene (R); and (ii) producing glyphosate resistant transgenic seed or transgenic plant progeny from said seed or plant population wherein the plant progeny are homozygous (RR) or heterozygous (Rr) for the glyphosate resistance transgene.
