Abstract: The effects of different eco-environments on the quality of strong-gluten wheat ‘Shaanyou 225’ are studied. The results show that the quality ‘Shaanyou 225’ is good and stable in different ecosystem areas and has achieved the standard of good-quality bread wheat of China. A ecosystem area of dry fertilizing plus rain and stow soil or middle fertility plus stout soil and irrigation is the suitable ecosystem area for producing good quality ‘Shaanyou 225’. Its quality can achieve strong-gluten wheat standard. The wheat grains of which the mature period is more than 4 months are suitably selected to make wheat flour and its quality is the best.
