Abstract

False chinch bug (Nysius cymoides (Hem: Lygaeidae)) is one of the most important pests of canola in Iran and causes  significant damage to this crop annually. In order to evaluate the resistance of canola cultivars to this pest, 12 cultivars included Arshitect, Okapi, Nafis, Atura, Nima, Gabriella, Koodiak, Garo, Brotus, Rohan, Deffusion, and Traviana were studied in a completely randomized design in the research farm of the Faculty of Agriculture of Kurdistan University in 2020 and 2021 years.  In this study several parameters related to the false chinch bugs (Weight and population density of the pest) and several plant parameters (secondary branches number, diameter of the main branch, pod length, flowering branch length, seeds number per pod, 1000 seed weight and seed yield) were evaluated. The results of data analysis showed that there was significant difference between cultivars in terms of some parameters including seed weight, plant length, pod length, number of seeds per pod, 1000 seed weight, and yield at a 5% probability level. Also according to the multivariate analysis of variance, there was no significant difference between the type of trap and the type of cultivar, but there was a significant difference between the types of traps. In total, using cluster analysis by Ward's method and based on Euclidean distance, 12 studied cultivars were divided into four groups: resistant, semi-resistant, susceptible, and semi-susceptible.
