A new malting barley cultivar, “Sinho”, with a resistant gene (rym5) to barley yellow mosaic virus (BaYMV) was developed by the barley breeding team of National Crop Experiment Station (NCES), RDA in 1999. This cultivar was derived from the cross between

“Jaeanchal” is a new six-rowed, naked and waxy barley cultivar developed by National Crop Experiment Station (NCES), RDA in 2001. This cultivar was derived from a cross between “Suwon261” and “SB881115-6” in 1989. The final selection was made at NCES in 1

보리호위축병(BaYMV) 상습 발병지에서 쌀보리인 백동을 공시하여 건전주와 이병주의 농업형질 등을 비교 조사한 결과를 요약하면 다음과 같다. 1. 보리호위축병에 이병된 주는 건전주에 비하여 SPAD 값이 13.7정도 낮은 값을 보였으며, 출수는 10-11일정도 지연이 되었고, 건물중이 75%, 간장은 68%, 수수가 49% 감소하였다. 2. 이병주의 절간장 감소는 이삭을 제외한 상부로부터 제1-6절간에서 나타났으며, 그 중 제3-5절간장에서 감소율이 75-80%로서 가장 켰다. 3. 보리호위축병에 의하여 망장이 17-19%, 입수가 47%, 천립중이 60%, 주당 입중이 78% 감소하였으며, 종실에서는 폭과 두께에서 감소되었고, 종피색의 색도에서는 명도는 낮았으나 적색도는 높게 나타났다.

A rapid and sensitive assay for specific detection and identification of barley yellow mosaic virus(BaYMV) was set up using the reverse transcriptase polymerase chain reaction(RT-PCR). A couple of primers was select to discriminate the viruses. PCR fragments of BaYMV(ca.0.9 kb) were obtained by using the method designed for BaYMV capsid protein. RT-PCR fragments were cloned with vector pT7 Blue and the resulting clones were sequenced. Capsid protein of BaYMV consisted of 297 amino acids and 891 nucleotides. The capsid protein sequence of BaYMV showed that 98% of nucleotides and 99% of amino acids homology.
