Karnataka is India's largest producer of mulberry silk, contributing about 60-65% of the country's total silk production. The state's favorable climate, extensive sericulture infrastructure, and traditional expertise make it the silk hub. While Jammu & Kashmir is known for temperate silk (bivoltine) and Assam for other silk varieties, Karnataka dominates mulberry silk production with districts like Channapatna, Ramanagaram, and Kollegal being major centers.
