Experimental trials were conducted at Integrated
Pest Management Programme, National Agriculture Research Centre Islamabad,
to evaluate the resistance of host plants (cereals) against Rhopalosiphum
padi (L.). For evaluation of susceptibility, twenty varieties/-advanced
lines of National Uniform Wheat Yield Trails (NUWYT) Normal (N) of year
2004-2005 were used. In seedling bulk tests varieties/advanced lines were
grouped into three categories resistant, moderately resistant and susceptible.
Data from seedling bulk tests showed that DN-47 and PR 87 lines of wheat
were resistant to aphid as compared to the other varieties/-advanced lines.
In antixenosis tests varieties/-advanced lines were grouped into three
categories, least preferred, moderately preferred, highly preferred. Lines
V-01180, DN-47 and PR-84 were least preferred, sixteen varieties/-advanced
lines were moderately preferred and only one variety V-9021 was found
to be highly preferred.
