Abstract

A new silkworm variety SooOkJam for spring rearing season is F1 hybrid between Jam157, a japanese race bred from introduction breeding and Jam158, a chinese race from introduction breeding. In the local adaptability test performed at 8 local areas in spring of 2011, the hatchability rate of SooOkJam was recorded 2% higher than the authorized silkworm variety, DaePoongJam. The larval period was recorded 12 hour shorter than DaePoongJam. The pupation percentage was recorded 0.8% higher than DaePoongJam. Single cocoon weight (2.40 g), Cocoon yield (22.6 kg) and best cocoon rate (95.5%) was similar to DaePoongJam. The concentration of DNJ was measured 4.12 mg in SooOkJam, lower than DaePoongJam (4.45 mg). Test of the artificial diet of SooOkJam showed excellent adaptability of the artificial diet for larval period from 1st to 3rd, similar to KumOkJam. In the Paecilomyces tenuipes production ability test, the pupal weight of SooOkJam was 1.61 g/individual, similar to DaePoongJam (1.65 g/individual).

수옥잠은 부화비율, 화용비율이 높은 강건 다수성 애누에 인공사료 적합품종을 육성하였다. 이 품종의 일본종계 원종 잠157은 2003년 K305와 9671을 교잡 육성한 무늬품종이고 중국종계 잠158은 1997년에 CBJ와 9032을 교잡 육성한 선발 육성한 무늬 없는 품종이다. 실용 부화비율은 97%, 화용비율은 95.9%로 우수하였고, 전견중이 2.40 g, 1만두 수견량은 22.6 kg, 상견비율 95.5%로 대조 품종과 비슷한 성적을 나타냈다. 실켜기 성적에서 견사장은 대조 1,433 m보다 78 m 짧고, 견사량이 대조 보다 적은 49.6 cg 이었다. 견사섬도는 3.31 d이었다. 이품종의 잠종생산능력은 일본종계 원종 잠157의 산란수는 513개로 대조 대풍잠의 잠151의 525개와 비슷하였고, 중국종계 원종 잠1568 산란수 522개로 대조 잠152의 447보다 105개가 많아 산란성이 우수하였다.
