Abstract

Cross compatibility tests among various strains of silk-worms were conducted in order to determine which among parental combinations show high degrees of compatibility on the basis of fecundity and percent hatchability. Evaluation of the parents revealed that LBS6 gave the highest performance in fecundity, larval duration and single cocoon diameter while SW1 had the highest percent hatchability. No significant differences among number of cocoons per kilogram and single cocoon length were observed among the parents. SDS-PAGE evaluation of the hemolymph proteins of three parental strains revealed 47 hemolymph protein bands. Among parent strains, the highest similarity was obtained between silkworm strains LBS7 and LBS6 with similar lineage while lowest similarity was obtained between strains LBS6 and SW1 with different origin. Four protein bands (band nos. 14, 30, 41 and 47 were found to be unique to LBS7; six bands (band nos. 1, 2, 3, 4, 13 and 47) unique to SW1 and four protein bands (band nos. 6, 11, 15 and 43) unique to LBS6.
