Abstract: The variations of main quality characters of a strong-gluten wheat variety(Yumai 47) planted in different regions of Henan province were studied. The results showed that the main quality characters, such as wet-gluten content (WGC) and stability time (ST) in Farinograph, were decreased steadily along with reducing of the planting latitude from north to south and increasing of the longitude from west to east, especially for WGC, and this was considered as the results of the regular changes of the annual rainfall. Therefore, the annual rainfall was considered as one of the key factors to affect the wheat quality. The analysis of the values of main quality characters of the commercial wheat grains produced in different soils revealed a very significant correlation existed between NH4+-N content in soils and WGC or ST, and there had been found a significant positive correlation between the content of available P and K in soil and ST, while no such correlation for WGC. The schemes of balance application of fertilizer for different regions and soils were discussed.
