ABSTRACT
This experiment was performed to estimate some important indicators of performance on commercial silkworm hybrids and to compare commercial hybrids of Iran silkworm due to its production characteristics and study of superior hybrid selection and performance. In this experiment, eggs of eight commercial silkworm hybrids including hybrids of 104x103, 103x104, 32x31, 31x32, 154x151, 151x154, 154x153 and 153x154 as a treatment in the form 4 repeats was used and every repeat was involved 50 Lavrhybrids. After nurturing hybrids and gaining different characteristics records, first variance analysis and average comparison of traits was performed then we use two methods of assessment index and sub-ordinate function to integrate and aggregate. According to the results based on evaluation index method, hybrid 154x151 with the 799.4063 score gains the highest rank and then it was the 31x32 hybrid. Hybrids 104x103 and 153x154 also obtained the lowest score. According to the Sub-Ordinate Function 31x32 hybrid also obtained the highest rank with 13057.43 score. About 151x154 hybrids and 153x154 also obtained the lowest score. Based on results in hybrid 31x32 beyond desired hybrids has higher yield potential and its use is recommended.
