The insertion and excision of transposable elements often lead to alterations in the base pair sequence of a gene. This could contribute to polymorphism and genetic variation in maize ( Zea mays L.) germplasm. The objective of this experiment was to establish whether or not breeding material that showed genetic variability contained the transposable element Uq . Populations and inbred lines were crossed with a genetic tester containing c‐ruq , the receptor for Uq . Populations that contained the element Uq include Iowa Stiff Stalk Synthetic, Burrs White, Hays Golden, Iowa Long Ear, Lancaster, Kolkmeier, and Bsll. The inbred I159 also contained Uq . This study screened for only one of nine genetically characterized elements. The absence of Uq does not indicate the absence of other known or unknown elements.
