“…The 1982 virus mixture was somewhat more severe than the one used in previous years . The aphid and virus rearing and field-spreading methods were carried out as described in a previous work (COMEAU, 1976) . Pots were prepared for seeding outdoors by filling the bottom two-thirds of the pot with the native loam, and the top part with a 1 :1 mixture of native loam and Readi-Earth, a commercial mixture of vermiculite, peat and soil .…”

The Barley Yellow Dwarf Virus disease (BYDV) and the Russian wheat aphid (RWA) Diuraphis noxia (Mordvilko) have caused significant losses to wheat and barley in several areas of the world . Important sources of resistance to both BYDV and RWA have been found in Triticale . Different generations of interspecific wheat x Triticale crosses were produced and the progenies were screened for BYDV and RWA tolerance . Plants with equal chromosome numbers showed different levels of fertility. A significant correlation was observed between pollen fertility and seed set in primary florets (r -0 .57) . In general, pollen fertility, seed set and the number of euploid plants (2n = 42) increased from one generation to the next. The expression of BYDV tolerance varied from population to population . Additive effects were predominant in F1 and some backcross populations . A dominant effect of rye tolerance genes was also observed in few populations . A monogenic trait or a quantitative (polygenic) character would not agree with the observed segregation patterns . The heritability of this oligogenic tolerance was quite different between populations and in many populations the tolerance genes were only partially expressed . Some transgressive segregation for tolerance and sensitivity was demonstrated . The genes controlling tolerance ; to RWA in Triticale lines, Muskox 658 and Nord Kivu were not expressed in advanced lines resistant to BYDV . This indicates that tolerance genes for BYDV and RWA in these lines are located on different chromosomes .

“…Many methods have been developed for culturing aphids in the laboratory either in large numbers on growing plants (e.g. Mackauer & Bisdee, 1965;Comeau, 1976;Woolcock, 1989), or individually or in small groups on seedlings or excised leaves (e.g. Noble, 1958;Markkula & Rautap~t~, 1963;Fraval, 1968;Blackman, 1971;Di Pietro & Dedryver, 1986;Ridland et al, 1988).…”
