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 sources, HF-resistant germplasm KS18WGRC65 (TA5110, Reg. no. GP-1042, PI 688251) was developed by Wheat Genetics Resource Center at Kansas State University as a breeding stock that carries resistance gene H26 from Aegilops tauschii Coss. 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 or other agronomic characters, making it a suitable source of HF resistance for wheat breeding.
