Abstract

We investigated fertilization rate, hatchability rate, pupation rate and cocoon quality etc to selecting good characteristics of the wild silkmoth, Antheraea yamamai using method of indoor-and outdoor-rearing. As results of indoor rearing, the healthiness of A. yamamai was better in light green colour strain than that of dark green colour strain, but cocoon quality was better in dark green colour strain. There was a little effect to selecting major characteristics in grade of A, B and C strain classified with cocoon weight. $F_1$ hybrid was lower in fertilization rate and hatchability rate than parent, but higher in pupation rate and cocoon quality. There was no effect of heterosis in $F_2$ hybrid. In case of outdoor rearing, mortality rate was lower than that of indoor rearing but missing larva was higher. In addition, outdoor rearing is higher that indoor rearing in cocoon weight, cocoon shell weight and cocoon shell rate.

천잠의 우량형질 선발을 위하여 실내와 야외에서 사육하면서 수정율, 부화율, 용화율, 전견중 등을 비교 조사하였다. 실내사육 결과, 유충체색에 있어서 강건성은 담록체색이 우수하였으나, 견질은 암록체색이 우수한 것으로 나타났다. 전견중에 따라 분리된 등급간에는 약간의 차이가 인정되었다. 또한 $F_1$ 교잡종은 수정율과 부화율은 원종보다 떨어졌으나, 용화율과 견질 등에서 잡종강세효과가 확인되었으나 $F_2$ 교잡종은 효과가 인정되지 않았다. 야외사육의 경우 실내사육에 비해 감잠비율은 낮으나 유실잠이 많은 경향을 보였다. 또한 전견중, 전층중 및 견층비율 등 견질성적 이 실내사육보다 우수하였다.
