  • Normally the first generation of hybrid is supplied for farm rearing, precise and labor saving sex discrimination is needed. The new strain "Hansaengjam" is sex-limited (female:larval markings, male:no-markings) strain which was bred from both sex-limited strain Japanese originated Jam 153 and Chinese originated strain Jam 154. Productivity test of Hansaengjam during 2007 and 2009 showed high healthiness and cocoon yield. The Hansaengjam is evaluated as an excellent strain from healthiness, cocoon yield and other test results.

  • Yeonnokjam is a newly bred high yield special silkworm strain for spring rearing, bred from Japanese originated green cocoon spinning strain Jam 315 and Chinese originated white cocoon spinning strain Jam 316. This strain showed high hatching ratio of 96% and high healthiness of 96.7% of pupatin ratio. And its spins heavier cocoon with somewhat shorter fiber length but thicker fineness. The merits of these_strains are short larval period and labor saving, and its breeding goals are producing polish green silk and use for education.

  • We investigated sericin extracted from sericinjam, which was inbred at National Academy of Agricultural Science, Suwon, Korea. Sericinjam sericin is composed of 5 fractions: 250 kDa, 120 kDa, 90 kDa, 70 kDa and 40 kDa. Amino acid analysis showed that the major amino acids of sericinjam sericin were Ser, Gly, Asp, Glu, Thr and Ala. Infrared spectra showed that sericinjam sericin has $\beta$-sheet structure. Thermal property of sericin was investigated using DSC and then they showed characteristic degradation peak at around $215{\sim}240^{\circ}C$.
