To detect the effect of ultraviolet (UV) radiation on some economic traits of the silkworm, Bombyx mori L. variety Urboshi-1, 5-day old pupae were irradiated with 366nm wavelength of UV-rays at a distance of 10.6 cm for 1, 5 and 10 min. UVradiation had significant effects on majority of the 16 characters considered for the study. Three different lines viz. U1-DW, U1- LW and U10-LD were isolated on the basis of their cocoon shape and size from the rearing of the 1st radiated generation (R1). The rearing of the R2 generation produced cocoons which conformed to the shape and size of the cocoons as selected in the R1 generation. The selected lines showed better rearing performance than the control for majority of the characters, especially the cocoon characters which had direct relationships with the commercial cocoon production. Cocoons produced in the R2 generation were utilized in the R3 generation. The evaluation of the cocoon characters of the R3 generation revealed that U1-LW and U10- LD lines hold promise for commercial exploitation. Moreover, U10-LD also showed the lowest larval mortality.
