In order for development and maintainance of a domestic sericulture industry, production and supply with grand parent silkworm egg of F1 hybrid was conducted under preserving pure line of breeder' s stock of silkworm egg every year. Approximately, 8,500∼9,000 moths have continuously been producing from 2009 year. From 2009 year it has continuously been supplying with about 6,500 moths. Because pebrine is the most fatal disease in silkworm, it is very important to block pebrine delivering to next generation, as performing pebrine examination of silkworm egg. This study was excuted to produce nonpoisonous superior egg. As the inspection result, basic and grand parent silkworm egg of F1 hybrid showed 0.1∼1.3% detection ratio of the yearly mean. For research dissemination silkworm eggs silkworm egg quality supplier or agency five years examined. Silkworm egg weight (10g) per box of good quality survey showed that over the baseline. Number of silkworm eggs in the box or more of baseline was good. normally oviposited ratio 2009 and 2010, the percentage of the reference value(95%) was less than. That gradually improved from 2011 was better than in the baseline. As the result of investigation results of error cross ratio, the average record of the entire country gets better gradually, but standard record (1%) was exceeding. The deviation was recorded on a large scale with 0.8%∼3.0% according to the agency and the trade. The error rate of silkworms eggs is poor from 2009 to 2011, but from 2012 down to quality improvement.
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 wihte cocoon spinning strain Jam 316. 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. 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. WhangBoJam for spring rearing season is F1 hybrid between Jam317, a japanese strain bred from introduction breeding and Jam318, a chinese strain from introduction breeding. In the local adaptability test performed at 8 local areas in spring of 2012. Geumgangjam for spring rearing season is F1 hybrid between Jam159, a japanese strain bred from introduction breeding and Jam160, a chinese strain from introduction breeding. In the local adaptability test performed at 8 local areas in spring of 2013.
Mulberry has been used primarily to feed a silkworm until now, however, it has been diversified to recent a functional utilization and mulberry fruits production purpose of mulberry. Accordingly, we need to develop suitable varieties breeding for a new utilization. So, in this study, the contents of 1-deoxynojirimycin(1-DNJ) in mulberry leaves was investigated, and the outstanding strain to mulberry fruit production purpose through investigating a genetic resources was selected. A tetraploid was made, and a mulberry fruit’s characterization was investigated through a production of seedling strain from outstanding varieties of mulberry fruit. Besides, it was multiplied through a induction of genetic resources from foreign countries, suitable strains as a large fruit, a resistance capacity of popcorn disease, and a belated formation for mulberry fruit producing purpose was selected through investigating a genetic resources. Finally, a tetraploid line was made through a treatment of colchicine in winter buds, and promising seedlings of mulberry fruits production was produced.
In the Republic of Korea, more than 300 silkworm strains and 600 mulberry tree varieties remain under conservation in a government institute. Silkworm strains are annually reared, and scores from indoor rearing are analyzed for consistent character maintenance. Thus, silkworm strains with unstable heritable characters are discarded for better keep pure lines. Nevertheless, still much confusion on the genetic stock exists. Such abundance reversely may indicate the difficulty and complexity to discriminate one strain from the others. In order for further systematic maintenance of sericultural stocks kept in Korea we will analyze character quality of a diverse array of strains originated from several sericulture-practicing countries. Furthermore, 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 and mulberry tree although more breeds should be investigated for further complete pictures. Sericulture genetic resources are current and future ground for evolution of new properties and, thus, they should be well organized and kept with systematic manner, because they may eventually provide ground for the production of new properties kept in the genetic resources.
The mulberry syncarp harvest is finish, and then, in next year, it is pruned mulberry branch to which mulberry syncarp fruit is faithfully opened, or the type and vitality of tree is adjusted. In this period, the pruning mulberry branch is not used, and thrown out. Therefore, in this study, the results was gained that it performed the field proof studying like as the field adaptability of silkworm rearing technique with pruning mulberry branch for the bare grounds and mulberry syncarp harvest farm of the house, the development of mulberry leaves’ goods used with mulberry leaves, etc., for being the judge whether not possible to the new income of farm. First, when silkworm was rear with using the mulberry syncarp and leaves, the rearing period was from the last ten days of May to the first ten days of June when was overall consider the characteristic of mulberry syncarp kind, cultivation patterns, pruning periods of mulberry after harvesting, etc. Second, in the fifth year of organic farming cultivation, when it was processed and sell each 136kg of the mulberry leaves tea and mulberry leaves powder with the 1,360 kg of the fresh mulberry leaves from the four hundred of Ik-Su mulberry, the income was about 1,647 million won. Third, when silkworm was rear with using the mulberry syncarp and leaves, the silkworm brushing amount was suitable for deciding on the 250~300kg basis per silkworm box after calculating total an output of mulberry syncarp and leaves.
