THE HESSIAN FLY is a destructive pest of bread wheat (T. aestivum L., 2n = 6x = 42, AABBDD) and durum wheat T. turgidum L. ssp. durum Desf. Husn., 2n = 4x = 28, AABB) in most production areas of the world. To date, 29 major genes conferring resistance to Hessian fly have been identified and are being used in cultivar improvement (McIntosh et al., 1998). Most of these genes confer resistance only against specific biotypes of the Hessian fly.
Cultivated rye (S. cereale L., 2n = 2x = 14, RR) is an important source of genes for insect and disease resistance in wheat. To date, 12 genes conferring resistance to various diseases and insects have been transferred from ...
