Abstract

The present study was conducted by comparing the production capacity of six domestic commercial hybrids with 14 imported commercial. In this study, 3 replications included half gram from the beginning of egg hatching were placed in hatchery envelopes. Considering the same breeding site, the best commercial hybrids in terms of yield can be identified and introduced. This experiment was conducted in a completely randomized design and data under Graphpad Prism and Minitab were analyzed. The analyses were performed using ANOVA and differences between means were examined using the Tukey test. According to the results, 872*871 and 103*104 hybrids were the best population hybrids with about 98.5% hatching (p < 0.05). The total weight of the cocoon obtained in hybrids with Q*B 9/667 and L*OR and QA*BB with 663 grams were in the top group (p < 0.05). The results showed that the average cocoon shell weight in hybrids 872*871, 154*153, S*M and 103*104 in the group, had a significant increase (p < 0.05). In the case of cocoon production for 10,000 larvae, 153*153, 872*871 and S*M hybrids had the best cocoon production, respectively (p < 0.05). Specifically, the number of cocoons per liter was S*M and 872*871 hybrids with the lowest number of cocoons per liter as the best group in this trait. The overall conclusion of this study shows that domestic hybrids in many economic traits in silkworm breeding are or better than imported hybrids and can be used as a suitable alternative in this industry in Iran.
