For obtain basic data for application on two-rowed malting barley breeding program, it was investigated that growth and diseases resistance to 353 varieties of Korean(114) and induced(239) genetic resources used in barley breeding in current. Investigated growth and diseases characters were major yield components and viral and powdery mildew resistant. Hopumbori was checked cultivar to comparing the growth characters of the materials.
Domestic materials(DM) was superior to induced materials(IM) in heading time. The check was 1st May and 33% of DM was earlier to the date while only 7% of IM was before the date of check cultivar. In examination of late heading-date(late 6th May) ratio, IM showed more late maturity characteristics than DM. The tillering capacity was better in DM as 49% and 23% of IM in spike number per unit area, respectively. 58% of IM showed longer the spike length, while 20% of IM showed more kernel number per spike, respectively, than the check variety. It was a little resistant materials to viral disease. In powdery mildew resistance test, 51 materials showed resistant responses such as no infection or necrotic spots. The related resistant genes were assumed 5 genes, Mlg, Mla12, M1k+M1a9 and M1a1 or Mlg+M1(CP).
