Aluminum (Al) toxicity is a major limiting factor in winter wheat production in Oklahoma and the use of Al tolerant varieties is one solution to this problem. No quantitative data exists on the ranking of Oklahoma's mostly grown winter wheat varieties (Ok101, Ok102, 2137, 2174, Jagger, Jagalene and AP502CL). This study, established to examine and rank the acid tolerance of common winter wheat varieties was conducted in 2004 and 2005 seasons at a site with a history of low pH. Regression analysis was performed for grain and forage yield against Al saturation for each variety. The varieties displayed different levels of Al tolerance; however, none of them was exclusively dominant in Al tolerance. Therefore, the varieties were categorized into three groups (A, B, and C) based on yield potential with respect to soil Al saturation percentage: group A as the most tolerant and C the least Al tolerant. Group A included: 2137, Ok101, Jagger, and Jagalene. Group B consisted of Ok102 and 2174 while group C contained Custer and AP502CL. In group A, 2137 was found more favorable due to its higher grain and forage yield potential. Among all varieties, soil Al had more impact on forage yield than grain. Production of “Al tolerant” winter wheat varieties is of great economic benefit to Oklahoma's producers. In contrary, producers should avoid “Al susceptible” varieties in low pH soils. Therefore, in terms of Al tolerance, results of this study indicate that group A>B>C a factor producers should put into consideration in variety selection.
