| The study was done to provide technical and theoretical foundation for wheat quality breeding,and to make clear the current situation and problems of wheat varieties or lines in Yellow and Huai River Valley Winter Wheat Zone.The quality properties of 324 winter wheat varieties or lines,sampled from wheat region test in Yellow and Huai River Valley Winter Wheat Zone,which contained test weight,protein,wet gluten,sedimentation,water absorption,stability time,area and maxium resistance were summarized.The results showed that the average of protein and wet gluten content of those varieties were higher than that of the standard (Protein(%,dry base)≥14%,Wet gluten(%,14% wet base)≥30%)in this zone,but the chatacteristics of stability time, sedimentation, area and maxium resistance were poor, leading to lower gluten intensity or worse flour processing quality,especially in the northern of Yellow and Huai River Valley Winter Wheat Zone. It was suggested that the quality of the four properties were improved gradualy in recent years. |
