벼 2기작 재배의 전기작 재배에서 농업적 특성 및 품질 등을 고려하여 선발한 유망계통 ‘밀양255호’의 주요 특성을 요약하면 아래와 같다. 1. 극조생 공시계통인 ‘밀양255호’의 출수기는 7월 3일로 대비품종인 ‘진부올벼’보다 2일 늦었으며, 간장과 수장은 각각 58.3 cm, 16.0 cm이며, 주당수수와 수당립수는 각각 18.0개 52.5개였다. 수량은 394 kg/10a로 12%정도 증수되었다. 2. ‘밀양255호’의 현미의 길이, 폭 및 두께는

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.
