Host-Reaction of Some Chickpea Genotypes to Some Fusarium oxysporum f. sp. ciceris Races in Syria

Alloush, L. A.R., S. Al-Maghribi and B.A. Barhoum. 2024. Host-Reaction of Some Chickpea Genotypes to Some Fusarium oxysporum f. sp. ciceris Races in Syria. Arab Journal of Plant Protection, 42(1): 137-142. https://doi.org/10.22268/AJPP-001216 This study aimed to evaluate the reaction of chickpea germplasm, including some winter chickpea cultivars (Ghab1, Ghab2, Ghab3, Ghab4, Ghab5), spring cultivars (Al-Bayyadi and Al-Marrakchi) and chickpea genotypes (FLIP03-118, FLIP03-142, FLIP05-44, FLIP95-67) to infection with different races (0, 1B/C, 2, 3 , 5 and 6) of Fusarium oxysporum f. sp. ciceris under semi-field conditions in Al-Ghab region, Syria during 2021, using a scale based on disease intensity index (DII). The results obtained showed a range in the reaction of tested genotypes which ranged between resistant to moderately resistant in most genotypes, except Ghab3 that was sensitive to race 3, and AL-Marrakchi that was sensitive to races 2 and 3, and FLIP95-67 was sensitive to race 0. Whereas FLIP03-142 showed a different reaction compared to the rest of the tested genotypes to race 3, as its resistance increased from moderately sensitive at flowering stage to resistant at maturity stage. The results obtained also showed a decrease in the resistance level of most genotypes with age. Keywords: Chickpea, races, wilt, cultivars, accessions, resistance, Al-Ghab, Syria.
