The mapping population comprised 122 F2 progeny of the cross, JIC2010001 (called 'A') x JIC2010003 ('C'). Maps were constructed with MapMaker v.3.0, and positions were verified manually by examining recombination events. Ae. umbellulata single-chromosome addition lines in T. aestivum cv 'Chinese Spring' were used to determine chromosomal locations of RFLP loci in Ae. umbellulata.
