Abstract

A new silkworm variety "DaeBakJam" for spring rearing season is F1 hybrid between Jam155, a japanese race bred from introduction breeding and Jam156, a chinese race from introduction breeding. In the local adaptability test performed at 8 local areas in spring of 2010, the hatchability rate of DaeBakJam was recorded 96% similar to DaePoongJam. The larval period was 3 hour shorter than DaePoongJam. The pupation percentage was recorded 0.2% higher than DaePoongJam. Single cocoon weight (2.72 g) and Cocoon yield (25.4 kg) was higher than DaePoongJam. The concentration of DNJ was measured 3.28 mg in DaePoongJam, lower than DaePoongJam (3.48 mg). Test of the artificial diet of DaeBakJam showed bad adaptability of the artificial diet for larval period from 1st to 3rd, but KumOkJam showed excellent adaptability of the artificial diet. In the Paecilomyces tenuipes production ability test, the pupal weight of DaeBakJam was 1.69 g/individual, higher than DaePoongJam (1.59 g/individual).

대박잠은 기존 보급 누에품종보다 화용비율이 높은 강건성 품종으로 대조 품종대비 5령 3일 유충 무게가 10% 무겁고, 전견중이 무거워 수량성이 높은 다수성 품종으로 육성하게 되었다. 이 품종의 일본종계 원종 잠155는 1999년 NB7과 NB18을 교잡 육성한 무늬 없는 품종이고 중국종계 잠156은 1999년에 도입한 CB을 선발 육성한 무늬없는 품종이다. 이 품종의 사육성적은 화용비율이 96.4%, 전견중이 2.72 g, 1만두 수견량은 25.4 kg으로 대조 품종보다 우수하였다. 실켜기 성적에서 견사장이 1,506 m, 견사량이 53.2 cg으로 1만두 생사량 4.92 kg으로 많아 우수하였고, 견사섬도는 3.19 d 이었다. 잠종생산능력은 일본종계 원종 잠155의 1나방당 산란수는 533개, 중국종계 원종 잠156의 산란수 629개로 산란성이 우수하였다.
