Title	Recurrent selection using male sterility and hydroponic tiller culture in pedigree breeding of wheat
Journal	Plant Breeding
Year	2000
Volume	119
Pages	440-442
Author	Marais GF Botes WC Louw JH
Abstract	Summary: A procedure for recurrent selection based on the male sterility gene, Ms3, was implemented. To facilitate the production of large numbers of hybrid progeny, a simple hydroponic system was developed in which male-sterile tillers cut at the flowering stage can be pollinated and maintained for about 8 weeks-long enough to produce a large quantity of viable hybrid seeds. The recurrent selection steps were integrated with a pedigree breeding programme employing different selection cycles for male and female plants. F1 female plants are subjected to a single screening for seedling resistance. In addition to F1 seedling screening, F2-F4 male families are field-selected for disease resistance, agrotype and quality in a pedigree programme before being used in crosses
