The breeding procedures in a particular crop are determined by its
pollination system. By using genetic tools, plant breeders have learned to alter
a pollination system to exploit new methods of crop improvement. In several
cross-pollinated crops, the production of hybrid seed on a commercial scale was
made possible only through the use of cytoplasmic male sterility. The
manipulation of genes to secure genetic emasculation and facilitate outcrossing
has also attracted the attention of plant breeders working with self-pollinated
crops. The possibility of large scale cross-pollination in 'pred~minantly selffertilized crops, opens up new avenues of progress and offers unlimited opportunites for recombination and population improvement. In barley, genic male
sterility has been used rather extensively by Suneson and co-workers (Suneson,
1951; Suneson and Wiebe, 1962; Qualset and Suneson, 1966) for the development of synthetic barley populations. These populations have provided valuable material for variety selection as well as fundamental genetic studies.
