Chilli pepper is a strategic horticultural commodity for its economic, nutritional, and medicinal values and is used as a spice in a variety of cuisines all over the world. Induced mutation by gamma ray’s irradiation has been used to increase chilli resistance and quality. The objective of this study was to determine the optimum dose of gamma irradiation in inducing resistance in putative mutation(M1) on chilli pepper seeds. The seeds induced were infected by Pepper Yellow Leaf Curl Virus (PYLCV) and were irradiated with 0, 25, 50, 100,150,200, 250, 300, 350, 400, 450, 500, 600, 700, 800, 900, and 1000Gy. The plants (M1) were observed for their seed germination, leaf length, leaf width, and plant height. The results indicated that the best LD 50 irradiation was 288.269 Gy (y = 82.7847+ 0.0698x + 0.0002x 2 + 2.0082x 3 ). The results also revealed that plants irradiated with doses 150, 200, and 250 Gy were selected to be planted in the field.
