Analysis of the Correlation Between Various Biological and Economic Indicators of Mulberry Silkworms (Bombyx mori L.) Introduced from Uzbekistan

In this study, eight mulberry silkworm (Bombyx mori L.) breeds imported from Uzbekistan were evaluated under laboratory conditions at the Sheki Regional Scientific Center of ANAS based on five key biological and productivity indicators: survival rate, viability, cocoon weight, feeding period, and silkiness. The results revealed significant differences among the breeds, with the highest productivity observed in the Marvarid and Markhamat breeds. Correlation analysis demonstrated positive and statistically significant relationships between survival rate and viability (r = 0.788; p < 0.05), cocoon weight (r = 0.824; p < 0.05), and silkiness (r = 0.941; p < 0.01). In contrast, negative correlations were identified between feeding period and survival rate (r = −0.775; p < 0.05), as well as silkiness (r = −0.881; p < 0.01). Overall, the survival rate showed a strong positive association with cocoon weight and silkiness, and a negative association with the feeding period. These findings indicate that cocoon weight and silkiness are key productivity indicators, whereas a A prolonged feeding period adversely affects productivity. Therefore, the Marvarid and Markhamat breeds are recommended as priority candidates for selection and breeding programs. Keywords: mulberry silkworm, breed, hybrid, wet cocoon, silk, correlation
