Lygus spp.'ye karşı dayanıklı patlıcan (Solanum melongena) kaynaklarının araştırılması

Eggplant, an important species of Solanacae family, is rich for vitamins and minerals with a vegetable of great economic value. In Turkey, eggplant is produced both in open fields and greenhouses, and there are many problems that limit production and quality of eggplants. Lygus spp. is one of the emerging pest problems. Lygus is generally known as a cotton pest. But in recent years, open-field eggplant tests particularly in Korkuteli-Antalya, showed potentially economic damage of the pest on eggplant production. This problem has increased in open-field eggplant cultivation in recent years. To date, a line resistant to Lygus spp has not been reported. The objective of the study was to identify resistant sources of this pest in eggplant through field test. A replicated field trial involving, seven different varieties of eggplant, 250 different plants have been studied and observed in Korkuteli-Antalya region (2019). The eggplant genotypes were scored for resistance against Lygus damage. In the observations, especially meristem and flower damage were taken into account. Lygus damage to orobanche (Orobanche spp.) and potato beetle (Leptinotarsa decemlineata) have also been identified and measured. The data related to the findings obtained in this study was used in excel for statistical analysis. In this study, all forms of damage from Lygus spp. it is understood that eggplant's major damage was on the stem of the flowers. For this purpose, meristem and stalk observation method were used to test eggplant plants. And two genotypes with potential resistance against Lygus were identified. These sources are both S.macrocarpon, MM1127 and MM12209 materials, and they showed more than 60% resistance in both materials.
