Abstract

CABBAGE APHID is of serious pests all over the world. It causes severe damage in rapeseed fields in Iran. Application of resistant genotype is a useful method in diminishing aphid damage. To overcome this problem, the RESISTANCE of 12 rapeseed genotypes were assessed in split plot in time based on complete blocks design under field conditions during 2011-12 in Miandoab region. Genotypes and six sampling dates were considered as the main plot and sub-plots, respectively. Evaluation of RESISTANCE SUSCEPTIBILITY was done by using INFESTATION INDEX which included multiplication of infestation percentage of genotype in plots x mean of infested stem length (cm) x number of aphid peripherally of one centimeter of infested stem. Infestation began in mid May and continued to the second half of April, and its highest peak was recorded April 11th. The analysis of variance showed significant differences (p<%1) between genotypes, sampling times and interaction between genotypes and sampling times. Highest rate of infestation was recorded on genotypes RGS…3 and Bristol, and lowest infestation on Triangle, Sarigol, and Opera with > 18 and < 6 index, respectively.
