Effects of herbicides and crop years on the quality of winter wheat varieties

The wet gluten content, gluten spreading, baking value, technological water-absorbing ability and falling number of 4 wheat varieties were studied in 1 year with an average rainfall (2001) and 2 dry years (2002 and 2003). The canopies of the wheat varieties were treated with different herbicides (Granstar, Duplosan DP, Lintur, Mecaphar and Mustang).The effects of variety and crop year and the variety x crop year interaction were significant on all the studied characters. The variety x herbicide x crop year interaction was significant too, with the exception of the technological water-absorbing ability.The 5 herbicide treatments did not give rise to any significant difference in the bread-making quality of the 4 tested wheat varieties in any of the 3 years. The variety x herbicide and herbicide x crop year interactions either were not significant.The characters of the bread-making quality of the varieties differed considerably with the crop year and the herbicide Within the bread-making quality of one vari...
