Abstract
Recently, peoples are greatly concerned with global temperature change because global warming can be a potential serious effect on agriculture production such as yield reduction and poor grain quality. On the other hand, it can bring some beneficial effects through twice cultivation of rice in temperate region. In order to overcome this situation, we developed extremely early-maturing rice 'Milyang255' which heading date was similar with 'Jinbuolbyeo'. Based on agronomic characteristics of 'Milyang255', it has very short stature as 65 cm of culm length and slightly lower spikelets number per panicle compared with that of 'Jinbuolbyeo'. However, the grain appearance, palatability and other items were better than those of 'Jinbuolbyeo' in panel test of cooked rice. The milled rice yield of 'Milyang255' is 3.94 MT/ha at the early transplanting. Especially, its grain filling rate was higher and faster than Jinbuolbyeo and the head rice ratio in milled rice was also higher. Thus, 'Milyang255' can efficiently reduce the growth duration of rice cultivation and also be useful material for research on twice cultivation of rice in Korea.
