Abstract ▼ AI-Helper

In order for further systematic maintenance of silkworm stocks kept in Korea we analyzed character quality of a diverse array of silkworm strains originated from several sericulture-practicing countries. The analysis of about ten qualitative characters from 67 strains (13 of Japanese strains, 15 of Chinese strains, 14 of European strains, 6 of Korean and Tropical strains, and 19 of unknown origin) revealed a significant difference in the ten different qualitative characters among silkworm strains. In the analysis of quantitative characters, Japanese and European strains were highest in hatchability, the Korean and Tropical strains were highest in pupation rate, and unknown origin and Chinese strains were highest in cocoon yield and number of egg laid. With the connection of molecular genetic analysis the current data may provide the advanced ground for further systematic maintenance of valuable genetic resources of silkworms, although more breeds should be investigated for further complete pictures.

제안 방법

The each instar' feeding with new leaves was done 3 times per day. The test implement was arrangemented with 150 head per each straims from 2nd day of 4th instar.
After mounting, the environmental conditions which are most important, that is, temperature and humidity were respectively kept with 22~24 and 60~70% in order to protect for 7 days.

howed 2 voltinism and 4moltinism. In quantitative characteristics, cocoon shape showed various form such as spindle, peanut, long oval, long peanut and oval, and cocoon color was white and yellow (Table 2). In quantitative characteristics, japanese varieties showed 82%-hatchability, 82.
In quantitative characteristics, cocoon shape showed various form such as spindle, peanut, long oval, long peanut and oval, and cocoon color was white and yellow (Table 2). In quantitative characteristics, japanese varieties showed 82%-hatchability, 82.0%-pupation rate, 11.8 kg -cocoon yield and 323 eggs-number of egg laid (Table 3).
In quantitative characteristics of the nineteen unknown origin varieties, they showed 4 moltinism and larva color with pastel blue (Table 10). In quantitative characteristics, the unknown origin varieties showed 78%- hatchability, 83.
ith pastel blue (Table 10). In quantitative characteristics, the unknown origin varieties showed 78%- hatchability, 83.5% - pupation rate, 12.9 kg - cocoon yield and 359 eggs -number of egg laid (Table 11).
Most of cocoon shape was oval, and larva color was most pastel blue (Table 4). In quantitative characteristics, Chinese varieties showed 79%-hatchability, 82.7%-pupation rate, 12.8 kgcocoon yield and 377 eggs-number of egg laid (Table 5).
In tropical varieties, larva pattern, cocoon color and ant larva color was spindle, white and red brown, repectively (Table 8). In quantitative characteristics, the native and tropical varieties showed 81%-hatchability, 88%-pupation rate, 9.8 kgcocoon yield and 319 eggs-number of egg laid (Table 9).
