Abstract :Ditylenchus dipsaci insert ignore into journalissuearticles values(Kühn, 1857); Filipjev, 1936 insert ignore into journalissuearticles values(Rhabditida: Anguinidae); is one of the destructive agents of garlic and reduces yield and market value. One of the most practical and eco-friendly methods for nematode management is using resistant varieties. In the study, two endemic garlic species, Allium tuncelianum insert ignore into journalissuearticles values(Kolman); Ozhatay, Mathew & Siraneci and Allium macrochaetum subsp. macrochaetum Boiss. & Hausskn. insert ignore into journalissuearticles values(Alliaceae: Amaryllidaceae);, 10 mutant and 32 landraces garlic genotypes, Allium sativum L. insert ignore into journalissuearticles values(Alliaceae: Amaryllidaceae); were investigated for their resistance reactions to D. dipsaci and effect of D. dipsaci on some plant growth parameters. All experiments were conducted at Atatürk Horticultural Central Research Institute in 2019-2020. None of the genotypes was found resistant to D. dipsaci, and reproduction factors, which ranged from 2.6 to 12.7, were grouped from susceptible to highly susceptible. The Tunceli garlic genotype had the lowest reproduction factor insert ignore into journalissuearticles values(2.6);, 36.6% less than the highly susceptible Muğla6 genotype. Alata1, Muğla1, Muğla7 and Kula genotypes had the lowest decrease rate with nematode treatment at least in one of the plant growth parameters. The genotypes that had lower nematode multiplication and displayed better development under nematode infestation in this study are recommended for the field infested with D. dipsaci as sources for garlic breeding.
