EFFECT OF ECONOMIC VALUE CHARACTERISTICS OF NEWLY CREATED MULBERRY VARIETIES ON BIOLOGICAL INDICATORS OF SILKWORM

Résumé

sericulture remains one of the important agricultural sectors in many countries, especially in regions where silk production contributes significantly to rural economic development. The productivity of silkworms (Bombyx mori L.) largely depends on the quality and nutritional composition of mulberry (Morus spp.) leaves, which serve as the primary food source for the larvae. Consequently, the development of new mulberry varieties with improved economic and biological characteristics has become a key objective in modern sericulture research. The present study investigates the influence of economic value traits of newly created mulberry varieties on the biological indicators of silkworm growth and development. Particular attention is given to the effects of leaf nutritional composition, biomass productivity, and leaf moisture content on silkworm physiological performance. The research evaluates several important biological indicators of silkworms, including larval survival rate, larval growth dynamics, cocoon weight, cocoon shell ratio, and silk productivity. The study employs comparative experimental analysis using multiple mulberry varieties cultivated under similar agro-ecological conditions. Silkworm larvae were reared using leaves collected from different mulberry varieties, and their biological performance was systematically monitored throughout the larval development stages. The results demonstrate that newly developed mulberry varieties possessing higher economic value traits significantly improve the biological indicators of silkworm productivity. Improved leaf nutritional content leads to accelerated larval growth, higher survival rates, and increased cocoon yield. In addition, the study highlights the importance of selecting mulberry varieties with balanced biochemical composition, including optimal protein, carbohydrate, and mineral content, which are essential for silkworm metabolism and silk gland development. The findings of this research contribute to the optimization of mulberry breeding programs and provide valuable recommendations for improving sericulture productivity. The integration of high-yield mulberry varieties into sericultural practice can enhance both the biological efficiency of silkworm cultivation and the economic sustainability of silk production systems.
