Essay

In the system of semidiallel crosses the genetics of eight quantitative traits has been studied in 9 winter bread wheat cultivars of various breeding years. The directed changes of GCA effects as well as the ration of dominant and recessive genes have been revealed at all investigated characters during breeding from the old cultivars to the modern ones. The results of the path analysis showed the alteration of causal-effective relations between grain productivity and yield components. It has been also stated that durable winter bread wheat breeding for yield raising resulted in the increase of genetic diversity for almost all the the investigated characters.
