Interpretive Summary: Hessian fly is one of the most destructive pests of wheat in the US. This insect pest is mainly controlled by breeding resistant wheat cultivars. The resistance gene H26 was transferred from a wild wheat relative species called Aegilops tauschii. H26 provides high resistance to Hessian fly in the Great Plains area. This work has incorporated H26 into an elite wheat cultivar, 'Overley', to assist breeders to incorporate H26 in their breeding programs. The availability of H26 in an agronomically favorable genetic background should accelerate the utilization of H26 in controlling the Hessian fly.

Technical Abstract: Hessian fly (HF; Mayetiola destructor Say) causes severe damage to wheat (Triticum aestivum L.) worldwide. Several resistance genes have been identified in wheat and wild relatives, however, HF populations are under strong selection pressure and evolve rapidly to overcome resistance. To ensure the availability of resistance source when needed, HF resistant germplasm KS18WGRC65 (TA5110, Reg. No. ---, PI 688251) was developed by Wheat Genetics Resource Center at Kansas State University as a breeding stock which carries resistant gene H26 from Aegilops tauschii. KS18WGRC65 is a cytogenetically stable homozygous BC3F3:6 line derived from the cross between Ae. tauschii accession ‘KU2147’ and hard red winter wheat recurrent parent ‘Overley’. KS18WGRC65 exhibited no penalty for yield and other agronomic characters, making it a suitable source of HF resistance for wheat breeding.
