Abstract
A novel method of producing a plant with a marker closely linked to a target locus, in particular a nuclear male sterile target locus, is described. The method involves transformation of a group of plants in order to introduce a marker into each plant, and isolation of a plant with the marker closely linked to a target locus. The markers include visible markers and dominant conditional lethal markers. The method is of particular use for hybrid seed production where the target locus is a nuclear male sterile locus.
