Direct introgression of genes from diploid Aegilops squarrosa L into hexaploid wheat ( Tnticum aestivum L.) is an efficient way of developing stable, hexaploid lines with unique, useful genes. 39 such lines derived front direct crosses to determine the effects of Ac. squarrosa germplasm were field‐tested on productivity. Whereas some lines were agronomically inferior to the recurrent parent, others periormed at an equall or better level. In addition to the larget traits (Hessian‐fly and leaf‐rust resistance), other traits, including soilborne‐mosaic‐virus resistance and protein concentration, were improved.
