Abstract

Recurrent selection based on dominant male sterility has proved feasible in wheat (Triticum aestivum L.) breeding. Combining Ms3 with the technique of hydroponic tiller culture, little effort and space are needed to randomly intercross large numbers of selected male and female plants. Consequently, recurrent selection can readily be integrated with, and supplement, an ongoing breeding programme, such as pedigree. However, as is suggested here, it is also possible to base a breeding programme solely on recurrent selection. If mass selection is employed in the field evaluation of the male component, large populations can be evaluated very efficiently with relatively modest inputs. Such a strategy may prove especially useful to programmes with limited resources.
