This study aimed to determine the resistance levels of eggplant rootstocks, which were salt stress tolerant under controlled conditions, of interspecies hybrid eggplant rootstock candidates that stand out in terms of many characteristics. As genetic material in the research, 8 interspecies hybrid eggplant rootstock candidates (Solanum melongena x Solanum aethiopicum) developed within the scope of SAN-TEZ Project no. 0832.STZ.2014 was evaluated. In addition, AGR-703 and AGR-704 commercial hybrid eggplant rootstocks were used. Karabey F1 variety was used as a scion in obtaining grafted plants. It was determined that grafted and ungrafted eggplant plants, subjected to salt stress, decreased at varying rates compared to control plants, depending on the increased salt level in terms of the criteria examined. The salt stress created by different salt doses adversely affected the growth and development of grafted and ungrafted eggplant plants. However, these adverse reactions differed depending on rootstock/scion combinations. In conclusion, it was determined that the grafted eggplant genotypes performed better than the ungrafted Karabey variety. The best-performing combinations under salt stress conditions were determined to be AGR-704/K commercial rootstock/scion combination and RS-5/K and RS-7/K rootstock/scion combinations. As a result of the research, It was concluded that rootstock use is an effective control method against soil-based biotic factors and abiotic stress factors: It can significantly reduce the adverse effects of salt stress.
