Title	Inheritance of resistance to the Russian wheat aphid in an Iranian durum wheat line
Journal	Plant Breeding
Year	2002
Volume	121
Pages	180-181
Author	Assad MT
Abstract	Summary: The Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), is a major economic pest of small grains in many countries. An experiment was therefore conducted to determine the inheritance of gene(s) controlling resistance to RWA in a resistant tetraploid durum wheat line. This resistant line, '1881', was crossed to a susceptible line, 'Orejy-e-Kazeroon', and then F1, F2 and BCF1 (backcross to susceptible line) seedlings were screened in a greenhouse for RWA resistance following artificial infection. Resistance in '1881' was apparently controlled by one dominant gene. Since Dn1, Dn2, dn3, Dn4 and Dn5 have been reported to be located on genome D, it was reasoned that the resistance gene in '1881' is not allelic to them
