This experiment was conducted to evaluate the effect of temperature rise on the phenological development and yield of oilseed rape in temperature-controlled plastic houses located at Suwon in 2008 and 2009. Two varieties "Halla" and "Naehan" were grown using 1/5000a Wagner pots in the three plastic houses greenhouses in which temperature was controlled to ambient temperature (AT), AT+1.5℃, and AT+3.0 through the growing season. Compared to the ambient temperature, leaf appearance was speeded up by temperature elevation, resulting in earlier flowering by 7 and 19 days at the treatments of AT+1.5℃and AT+3.0℃, respectively. YGrain yield was decreased by approximately 15% for each temperature elevation of 1.5 ℃. The yield decrease was attributed to the increased sterility and the decreased grain weight under the higher temperature conditio
