This paper describes the modified hematoxylin laboratory method used at CIMMYT for screening wheat varieties for tolerance to aluminum. The CIMMYT wheat breeding program utilizes aluminum-tolerant materials and segregates selected under laboratory conditions in which seedlings are exposed to a low pH nutrient solution containing high levels of aluminum. The main effect of aluminum toxicity in the nutrient solution can be clearly detected because in sensitive seedlings cell division of the apical part of the root stops
