Use of different CMS systems in winter rye breeding for heterosis
2015
Artyukh,D.Y.
In a course of the reseacrh there was studied the collection of CMS forms and inbred lines. The research was realized in the conditions of the Republic of Belarus. As a result of realized research there were identified 30 best genotypes with a high degree of total combining ability. 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.
