Abstract
Durum wheat (Triticum turgidum L. var. durum) has been a source of several genes for resistance to the Hessian fly [Mayetiola destructor (Say)] in the United States. Previous studies have shown that the durum wheat cultivar ‘Jori’ has a single dominant gene, designated H2O, that conditions resistance to biotype D of the Hessian fly. The ‘Langdon’ D-genome disomic substitution lines were used in crosses with Jori to locate the gene. F2 segregation showed that the H2O gene for resistance to the Hessian fly is located on chromosome 2B. This is the first Hessian fly resistance gene that has been found in the B genome of wheat.This publication has 8 references indexed in Scilit:
