  • This study was carried out to investigate the influence of barley yellow mosaic virus(BaYMV) on agronomic characters in naked barley. A naked barley cultivar, Beagdong was evaluated for disease systems at naturally infected field, National Honam Agricultural Experiment Station. SPAD value of the infected plants by BaYMV was low as compared to healthy plants. Heading time was delayed by 10-11 days. Dry matter weight per plant, culm length, and number of spike per plant were reduced in the infected plants by 75%, 68%, and 49%, respectively. Length of internode was reduced in the first to the sixth internode from the upper part, especially, that in the third to the fifth internode was mostly reduced by 75-80%. Also, length of awn, number of kernels, 1000-kernel weight, and kernel weight per plant of the infected plant were reduced by 17-19%, 47%, 60%, and 78%, respectively. Lightness and redness for kernel color value of Baegdong were low and high, respectively.
