Abstract
A new source of resistance to greenbug toxin has been found in PI 268210 (Triticum tauschii (Coss.) Schmal 2n=14). The cultivar Langdon (T. turgidum L. durum group 2n=28) was used as female in a cross with PI 268210, and an amphiploid with 2n=42 chromosomes was obtained. The amphiploid was crossed with two hexaploid wheat lines, Kt-C and Little Club*9/WRT238 (T. aestivum L. aestivum group 2n=42). F2 segregations indicated that resistance to greenbug toxin in the amphiploid was conditioned by a single dominant gene. Chromosome pairing between the D-genome chromosomes of the amphiploid and the D-genome chromosomes of the T. aestivum lines appeared to be normal and chromosomal interchanges were not detected.
