Genetic diversity in a population is very important in the selection for the assembling of superior varieties. One method of plant breeding to increase diversity is by means of gamma ray irradiation (Crowder, 1986). The purpose of this study was to determine the diversity of eggplant (Solarium melongena L.) from seeds irradiated using gamma rays, especially in the growth and production of eggplant. Gamma ray irradiation research was conducted at Badan Atom Nasional (BATAN) Jakarta in May 2017, followed by research at Green House Plant Culture Tissue Culture Laboratory of Biotechnology Department of Agriculture Faculty of Islamic Kadiri University in Kediri from August 2017 until December 2017. Materials used are Eggplant Seed EP 1003 A with a long dose of irradiation 0 Gray, 100 Gray, 150 Gray and 200 Gray. Parameters observed were seedling power, plant height, stem diameter, and fruit (fruit length, fruit diameter and fruit weight). The results showed that gamma ray irradiation resulted in very significant differences in fruit weight one fruit and fruit weight one plant.
