Immunity to WSMV was found.in a Triticum Agropyron derived from Carsten x A. intermedium. This line was crossed with many common wheats and the F1 seed irradiated. After one backcross to common wheat and several generations of selfing it was concluded that a desirable translocation had not occurred. A backcrossing program was began in an attempt to establish an addition line. After two backcrosses of resistant plants to common wheat one disomic addition plant and three monosomic addition plants were identified. A fifth resistant plant with 42 chromosomes was also identified. This plant apparently involves a translocation but it is unstable cytologically. Methods are described by which a translocation could be induced and thus transfer the immunity to WSMV into common wheat.
