%X Choosing the best rootstock in grafted seedling production is very important. As rootstocks, genotypes within the species with the desired traits can be used, and intraspecific or interspecific hybrid rootstocks can be used. In this study, the hybridization ability of local eggplant genotypes (Solanum melongena) and relative eggplants genotypes (Solanum aethiopicum) and the hybrid seed characteristics obtained from the fruits of these combinations were determined. In this study, genetic materials consisting of 6 local eggplant genotypes (S. melongena) which were collected from different locations of Turkey were used as the female parents and 10 relative eggplant genotypes (S. aethiopicum) were used as the male parents. Both in the spring and autumn periods, 30 hybridizations were made for each interspecific combinations (S. melongena x S. aethiopicum). The fruit set number and the fruit set percentage (%) were determined in these hybrid combinations. In the study, seed characteristics (seed width (mm), length (mm) and thickness (mm), seed volume, seed shape index, 100 grain weight (g), abortive seed number / fruit, abortive seed ratio, and number of seeds / fruits) of the spring period combinations' hybrid seeds have been investigated. As a result of hybridization in two different periods; average fruit set percentage was determined as 47.2% depending on the parents. Crossing compatibility was found to be highest in the female parents of SM 6 (59 %), SM8 (55 %) and in the male parents of SA8 (58%), SA6 (55 %), SA12 (51 %), SA17-1 (50 %) genotypes. In terms of the number of hybrid seeds per fruit, the highest number was obtained from interspecific combination of SM6 x SA6 (275). It was followed by the SM8 x SA6 (202.2), SM12 x SA6 (200.0) and SM6 x SA17-2 (116.5) interspecific combinations. The results showed that the interspecific combinations of SM8 X SA6, SM6 XSA6, SM12 X SA6 and SM6 X SA17-2 were used as rootstock in the production of grafted eggplant seedlings in terms of both cross-species hybrid fruit set ratio and the number of seeds per fruit
