The quality of maize grains during storage is affected by unfavourable storage conditions, resulting in physicochemical changes in specifically amylose and starch content that lead to significant product qualitative and quantitative losses. The objective of this study was to evaluate the starch and amylose content of normal maize and quality protein maize (QPM) seed samples at different temperature treatments: in cold storage at 3.6 degrees C, at room temperature (18.5 degrees C) and at 30 degrees C for 0, 6 and 12 month storage periods, respectively. Sixteen genotypes were tested in a single trial at Potchefstroom in South Africa. Due to optimal growing conditions the seed was of excellent quality. Storage at 3.6 degrees C and 18.5 degrees C caused some reduction in amylose and starch content, although for starch it was not significant. On the other hand, storage at 30 degrees C significantly (P
