Winter wheat Sakura

Breeding method -pedigree: A higher level of disease resistance than in the parental variety Hana, combined with bread-making quality, broader adaptation and frost resistance were the main breeding goals.Single plant selection started in F 2 generation and it was performed in F 3 again.The plant progeny on two row microplots harvested in F 4 had good parameters of baking quality (sedimentation SDS and % N) and a high level of disease resistance.Since F 5 generation yield trials started progressively in more replications, in more locations and on different levels of intensity.At the same time disease resistance to cereal rusts (yellow, brown and stem), powdery mildew, Fusarium head blight (FHB) and brown leaf spots was evaluated in special nurseries with artificial infection and under natural field conditions.In generations F 2 , F 5 -F 13 frost resistance was evaluated in field-laboratory and laboratory tests in vernalization and freezing boxes.Quality parameters were examined since F 1 generation; in early generations for protein content and SDS sedimentation, later also for gluten index, % gluten, falling number, test weight and mixograph index and in late generations in baking tests.In F 8 generation the selected breeding line was tested in company trials in six locations.Disease resistance, grain quality, frost resistance and yield were found to be satisfactory, but the homogeneity was not sufficient.Plant selections were repeated and after company trials in F 9 the line under denomination SG-S1800-01 was applied for the Official Trials and registered as Sakura variety in F 13 .
