Abstract: 

The aim of this research was to evaluate the susceptibility of some genotypes and cultivars against chickpea leaf miner and its effect on seed and biomass yields under Syrian conditions in the Al-Ghab area. Hama, under natural infection conditions during the agricultural season 2019/2020. the results showed that there were no significant differences between the studied local chickpea cultivars (Ghab1, Ghab2 and Ghab3), all of which were susceptible to infection, and the highest infection severity was recorded on the ILC 3397 genotype = 8.4, and the lowest infection severity on the Genotype ILC5901 = 2.8, and significant differences were found in seed and biomass yields, between the experimental plots treated with pesticide and those left under natural infestation conditions, With the exception of the resistant genotype ILC5901, there were no significant differences between them, where the highest percentage of loss of seed and biomass yields was recorded on the susceptible genotype ILC 3397, amounting to 48.8% and 39.1%, respectively, and the lowest percentage of loss in seed and biomass yields was on the resistant genotype by 5.2 and 5.6%, respectively, and the percentage of seed yield loss for local cultivars ranged from 33.4-35.54%.

Keywords: chickpea, genotypes, yield, leaf minor chickpea.
