| Abstract: | In order to reveal the species degeneration of silkworm variety Fei · HeX Xiang · Yun in long production process, the data analysis software was used to detect the variability and correlation of the species from 2003 to 2010. The results show that the weight of whole cocoon, the amount of cocoon shell, cocoon shell rate and larval survival rate experienced considerable variation,while the rate of dead silkworm larvae in cocoon varied in a large range, which maintained the superior variety character. |
