Changes in seed quality parameter of three wheat varieties during one year storage at four different storage conditions, were studied. Applied storage conditions adversely affected quality changes in wheat seeds during one year storage. The most pronounced changes were observed for seeds kept at 40°C, RH = 45%, followed by seeds stored at 25°C, RH = 45%, while seeds kept at 4°C, RH = 45% or at warehouse conditions mostly showed minimal or statistically insignificant changes. Elevated temperature of seed storage caused a significant decrease of starch content, hectoliter weight, and wet gluten content, accompanied with increase in fl our acidity, and fluctuating in Zeleny sedimentation value. The intensities of observed changes showed strong dependence on wheat variety.
