Abstract
One of the results of recent reorganizations in Polish breeding is a remarkable reduction of financial support, which caused decrease in the number of running breeding programs. According to the data collected by the Research Centre for Cultivar Testing (COBORU), yield of the Polish winter wheat varieties is a several per-cent lower than that of foreign-bred ones. The variation in initial germplasm is of the same size for the Polish and the foreign breeding, since the cause must be related to the breeding procedures. The analysis of three years field experiments in six locations revealed a low frequency of strains significantly better than the remaining ones. This indicates a necessity to increase the number of lines entering examination process in the Polish breeding programs, in order to increase competitiveness of the bred wheat cultivars.
