Barley is a crop of the most effected cereals as climate change. Recently, the temperature has being increased in Korea peninsula. This study was conducted to find the responses the agronomic and quality by climate change. Three varieties, leading varieties in Korea, were sowing at 5 times from 25^th October to 15^thNovember with 5days interval and investigated the characteristic of the agronomic and qualities. The germination times is the less the ingrate temperature is short, the later its sprouting time is long, it was similar trends in all varieties. The integrate temperature unstill the heading time from the sowing time was short from 729? to 562? in keunalbori, 740? to 606? in Saesalbori and 751? to 611? in Hopumbori as the sowing time is later but the integrate temperature from heading time to maturing time is similar in three different barley. The No. of spike perµ³ was the much more the early sowing time than later it has. The 1,000 weights and test weight were heavy as the later sowing time but the contents of �-glucan and starch were similar as regardless sowing times.
