摘要：

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