ABSTRACT

Present investigation was carried out on two quantitative characters of the mulberry silkworm, Bombyx mori L. viz., total number of eggs laid per female and filament length of treated eggs with four doses (Control, 2.0, 2.5, 3.0%) of N-nitroso-N-ethylurea (NEU) under the following experiments: Genetic variability, heritability and genetic advance were estimated in different doses separately. A wide range of variation was recorded for both the characters and the major portion of the total variance was inherited with the phenotypical variance. The maximum heritability was recorded for total number of eggs laid per female and filament length showed a high genetic advance at all the doses. A high heritability with high genetic advance was also noted for the total number of eggs laid per female and filament length at all the doses.
