Testing the Quality of Chilli Seeds Resulting from Gamma-Ray Irradiation and Genetic Diversity

Gamma-ray irradiation is used to improve seed germination and plant seedling growth and is a way to increase plant genetic diversity. This research aims to (1) analyze the response of seed irradiation to germination and (2) identify genetic diversity. This study used a Randomized Group Design (RAK), which consisted of 6 treatment levels used, namely R0 = 0 Gry (control), R1 = 100 Gy, R2 = 200 Gy, R3 = 300 Gy, R4 = 400 Gy and R5 = 500 Gy. Each treatment had 20 replications, so there were 100 experimental units. Based on the results of this research show that the reticulum emergence test can be used as a basis for determining the germination and vigor of mutant and non-mutant chili seeds, while the use of the special molecular marker RAPD can be used to determine the level of diversity for mutant chili plants.
