Abstract
The growth characteristics and damage of naked barley infected with barley yellow mosaic virus (BaYMV) were investigated between resistant and susceptible varieties in habitual field plot of BaYMV BaYMV of the barley plants with typical disease symptom were identified by enzyme linked immunosorbent assay (ELISA) test. The visual degree (0-9) based on disease symptoms of BaYMV was different as 9 and 1 between susceptible variety Baegdong and resistant variety Naehanssalbori, respectively. Susceptible variety, Baegdong showed significant damage in culm length, number of kernel per spike and tiller per square meter but not in 1,000 kernel weight, so these results caused yield reduction to only 80% comparing to the control. Seed germination did not affected by BaYMV infection both in susceptible and resistant variety. In grain quality test, abortive grain yale and crude protein content were significantly increased compared to the control. The relationships between BaYMV infection and growth characteristics showed the negative correlations in culm length, number of tiller, 1000 kernel weight and yield, but it showed the positive correlation in crude protein contents. These results implied that BaYMV can affect not only barley growth and yield but grain quality.
