USE OF DIFFERENT CMS SYSTEMS IN WINTER RYE BREEDING FOR HETEROSIS
Abstract
The collection of CMS forms and inbred lines was studied. 30 best genotypes with a high degree of total combining ability were identified. Their morphological and agronomic characters were determined. Pair crossings of 20 MS-testers with 30 identified inbred lines were carried out. Sufficient quantities of hybrid combinations in breeding for heterosis were obtained. There were 30 sterile and 45 fertile combinations with a complex of agronomic characters among them. Their parental forms would be suitable for the development of new CMS systems such as MS-form + sterility fixing agent + fertility restorer.
