The Uq content of several breeding populations

Several maize breeding lines and populations were screened for the transposable element Uq. An isolation plot was used in which the lines of interest (assumed to be c/c) were detasseled and pollinated by a c-ruq tester. Resulting ears on the detasseled plants were heterozygous for c and c-ruq and the presence, absence and number of Uq could be determined. The following populations contained Uq elements:
