Abstract:

Peanut (Arachis hypogaea L.) is one of the most important oil crops in the world, belonging to the Leguminosae family and the Papilionacea subfamily, native to South America. Inefficiency of peanut regeneration system retarded its improvement through gene engineering. In this study we investigated the use of grafting to improve the survival rate of tissue cultured and transgenic plants. Plants of 14 days after germination were used as rootstock, and different grafting methods and plant management after grafting were investigated. The survival rate of different grafting methods ranged from 70-100% which is much higher than the survival rate obtained by directly transplanting transgenic plants after root induction.
