A. Delibes et al., HESSIAN FLY-RESISTANCE GENE TRANSFERRED FROM CHROMOSOME 4M(V) OF AEGILOPS VENTRICOSA TO TRITICUM-AESTIVUM, Theoretical and Applied Genetics, 94(6-7), 1997, pp. 858-864
A new Hessian fly (Mayetiola destructor) resistance gene from Aegilops
ventricosa and its transfer to hexaploid wheat is described. The 4D(4
M(v)) substitution line H-93-33 derived from the cross [(Triticum turg
idum H-l-l x Aegilops ventricosa no. 11) x Triticum aestivum H-10-15]
was highly resistant to the Spanish population tested. Resistance seem
ed to be inherited as a single dominant factor in the F-2 generation r
esulting from a cross of H-93-33 with its susceptible parent (H-10-15)
. Resistance in Ae. venticosa no. 10 was located on chromosome 4M(v) u
sing M-v wheat/Ae. ventricosa addition lines. The resistance gene tran
sferred from Ae. ventricosa no. 11 to H-93-33 (H27) is allelic with re
spect to that of Ae. ventricosa no. 10 and is non-allelic with respect
to the genes H3 and H6 from Monon and Caldwell respectively. The assi
gnment of H27 ene to chromosome 4M(v) is further supported by its link
age to a gene encoding isozyme Acph-M(v)1, previously located on chrom
osome 4M(v) in the line H-93-33. A new marker from homoeologous chromo
some group 4 (Amp-M(v)2) present in H-93-33 and the 4M(v) addition lin
e is described.
