Gene H16 in wheat for resistance to Hessian fly - 1988 - Printed

references

PI 94587 durum wheat, Triticum durum Desf., has resistance to biotype L of Hessian fly, Mayetiola destructor (Say) that has not been genetically characterized. Two genes, H6 and H11 from PI 94587, have been transferred into separate lines and characterized previously. Lines with H6 or H11 do not have resistance to biotype L that PI 94587 has. Our objectives were to transfer the gene(s) responsible for resistance to biotype L from PI 94587 to a susceptible line, and to determine if the gene(s) was different from known genes providing resistance to biotype L. We used standard greenhouse and growth chamber methods of analysis to determine resistance of seedling progenies to biotypes D and L of Hessian fly. A single partially dominant gene pair providing resistance to biotype L was transferred from PI94 587 to a previously susceptible durum wheat line ND D6647. Genetic studies indicated the new gene was not H9, H14, or H15. Reactions to biotypes, B, C, D, and L indicated it was not H10, or the 'Marquillo' gene. The newly isolated gene is designated H16
