The simplest and most effective method for solving the lodging problem, which causes serious yield losses in the production of wheat (Triticum L.), has been the use of shorter varieties. However, this situation eventually creates pressure on yield increases and decreases straw production. Thus, the determination of stem traits that impart lodging resistance and the development of nonlodging varieties has gained importance. This study examined the relationship between stem characteristics and lodging in 16 common and local wheat varieties. The lodging rate and angle were positively correlated with plant height, center of gravity length, potassium-calcium ratio, and plant weight, and negatively correlated with the second internode stem diameter, stem-bending strength, stem potassium content, and stem calcium content. A plant height that exceeded 104 cm increased the probability of lodging to 95%. The probability of lodging also increased considerably when the stem center of gravity was greater than 80 cm and the diameter of the second internode was smaller than 3.3 mm. A stem potassium content above 8500 mg kg-1 and a calcium content above 420 mg kg-1 were important for increasing lodging resistance. The local Gökala and Zerun wheat varieties showed high lodging resistance despite their tall heights.
