The effect of gamma radiation was studied on the native Thai Silkworm race 'Nang Lueng'. Silkworm eggs 1,2,3,4,5,6 and 7 days old were treated with radiation doses of zero, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 Gy. The most suitable radiation dose for selection purposes was in the range 1.5-2.5 Gy. When a radiation dose of 2.5 Gy was used for 6 day old eggs and selection undertaken to three generations, the cocoon percentage increased by approximately 34.4 %, and mean silk yarn length per cocoon increased by approximately 48 %. Other radiation doses has more limited effects. Egg number per female increased as a result of the radiation treatments but there was no effect on hatching percentage.
