영문 초록

The study aimed to rectify the present systems of malting barley production and seed renewal. Seed renewal system in Korea is maintained by 4 steps, which is similar to those in Japan, USA, Canada and New Zealand. However, Seeds produced by the renewal system are certified by the government whilest they are done by Seed Federations in other countries. Some seeds produced by the malting companies for the distribution to farmers are not even certified. Grains were sampled from 10 regions of Kyeongnam and Chunnam Provinces for the measurments of seed impurity rate, yield and quality. Impurity rate increased with the longer renewal cycle. Fifth year seeds had the impurity rate of 15.8%. They showed 14% lower grain yield, while third year seeds was 8% lower, than the first year seeds. The trend of impurity was more severe in Chunnam regions. Malt qurality was not much deteriorated up to third year seeds, but it was significantly bad in the fifty year seeds.
