Effects of Different Transplanting Dates and Agroclimatic Zones on Quality of Brown Rice and Yield of a Pigmented Rice Variety ‘Josaengheugchal’

This experiment was carried out to clarify the effect of various transplanting dates and agroclimatic zones on quality of brown rice and yield of a pigmented rice variety ‘Josaengheugchal’. The black density of brown rice in Jecheon (central inland region) showed a slight dif-ference among the transplanting dates, but in Cheongwon (western sobaek inland region) that had increased at the transplanting dates of June 10th to 20th. cyanidin 3-glucoside (C3G) content at the same transplanting date in Jecheon was higher than Cheongwon, and the overall C3G content was increased at the later transplanting dates. The optimum tran-splanting date estimated by brown rice yields and C3G content was May 11th (491 kg/10a) in Jecheon and June 16th (468 kg/10a) in Cheongwon.
