摘要：

The Russian A heat aphid (RWA). Diuraphis noxia (Mordvilko). is a major economic pest of small grains in Man. 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 F-1, F-2 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.
