영문 초록

This experiment was conducted to clarify the influences on threshing and awn removal for the germination of naked waxy barley variety Suwon 235, which has good palatability and cooking characteristics. Since those grains of this variety without protection of glume may be severely damaged by threshing machine during harvesting those grains were classified into three groups, healthy, damaged with worn embryo and damaged with broken embryo, and subjected for the germination tests. Grains with covered genotype were healthy by threshing at 600 or 900 RPM and followed by awn removal at 750 RPM, however, grains with naked genotype were only slightly damaged by threshing even at 900 RPM but were severely damaged by awn removal after threshing at both 600 and 900 RPMs. The damages of embryo with waxy endosperm by threshing were not related to waxy endosperm gene. Most of lines tested were not uzu but UZU (non UZU). The introduction of uzu gene in naked barley breeding program may help in decreasing the embryo damage by mechanical threshing which may require further study.
