New Silkworm Variety Qiantang × Xinchao Passes Approval

Provincial Department of Agriculture Announcement No. 2 of 2008 announced that the new silkworm variety "Qiantang × Xinchao", bred by the Sericulture Research Institute of the Provincial Academy of Agricultural Sciences, passed approval at the 37th Crop Variety Approval Meeting of the Provincial Crop Variety Approval Committee. "Qiantang × Xinchao" is a pair of medium-silk-yield silkworm varieties; this variety develops uniformly, has strong resistance, high cocoon yield, relatively large cocoons, and excellent cocoon quality. It is suitable for rearing in all sericulture areas of our province. Key points for rearing this variety: 1. During the young silkworm stage, it has a strong tendency toward light and crowding, so the seats should be evened out and the trays adjusted in time; 2. During the young silkworm stage, use leaves that are suitably mature but on the tender side, and during the grown silkworm stage, use mature leaves; 3. Its molting habit is relatively fast, so nets should be added and trays divided in time to prevent starvation molting; 4. It mounts the cocooning frame in a surging and concentrated manner and spins cocoons quickly, so preparations for mounting the cocooning frame should be made in advance.
