The objective of the study was to generate genetic variability through mutation induction using gamma rays. The first phase of the study was conducted in the nursery of the Research lnstitute of the Peruvian Amazon, where was evaluated biometric and phenological characteristics of plants obtained using irradiated seeds. Before planting the seeds was realized dosimetry of the seeds to estímate the time to be used in the irradiation of each treatment. The irradiation was made with gamma rays of Cobalt 60. The experiment had 8 treatments and 1 control (2, 5, 1 O, 25, 50, 100, 200, y 400 gray) and we used 100 seeds per treatment. The seeds were planted under a completely randomized design with 4 repetitions and the results were subjected to a comparison test of means (Duncan = 5%). The second phase consisted in the molecular analysis with AFLP markers (Amplified fragment length polymorphism...
