Abstract

A new silkworm variety, Juhwangjam, was bred for the producing of light pink colored cocoon. The Juhwangjam variety was selected and succeeded from the F1 of 2303 × BP Heehong in 2016 autumn. Hatchability (96%) and pupation percentage (97.6%) of Juhwangjam was matched to the authorization criteria for commercial silkworm variety. Laval period and other economical characters of Juhwangjam were similar to the authorized silkworm variety, Goldensilk. Cocoon yield of Juhwangjam in spring and autumn season was 20.0 and 14.3 kg, respectively. Therefore, a new silkworm variety, Juhwangjam for light pink cocoon, might be adaptable to culture in spring season rather than autumn season.
