초다수성이며 복합내병성인 고품질 통일형 벼를 육성하고자 복합내병성이며 수량성이 높은 ‘밀양160호’(‘아름벼’)와 준조생이며 내만식성이 높고 복합내병성 다수성 품종인 ‘용주벼’(‘수원333호’)를 부본으로 인공교배를 하여 ‘세계진미’를육성하였다. ‘세계진미’의 출수기는 평야지 보통기 다비재배에서 8월 17일로 중만생종이며, 간장은 82 cm로 ‘다산벼’보다 약간 크고 수당립수는 ‘다산벼’보다 적은 편이며 현미 천립중은 22.2 g으로 ‘다산벼’와 비슷하였다. ‘세계진미’는 불시출수, 수발아 및 포장도복은 없었으며, ‘다산벼’에 비해 내냉성은 약한 편이다. ‘세계진미’는 잎도열병, 목도열병, 줄무늬잎마름병, 오갈병 및 흰잎마름병(K1, K2, K3, K3a)에 강하고, 검은줄오갈병에는 중정도의 저항성을 보였으나 벼멸구에는 감수성이다. ‘세계진미’의 단백질함량은 7.9%로 ‘다산벼’ 에 비해 다소 높은 편이나, 아밀로스함량은 17.2%로 ‘다산벼’ 와 비슷하였다. 특히 ‘세계진미’의 물리성과 밥맛 관능검정결과 일반벼인 ‘추청벼’ 수준 이상의 양호한 취반특성을 보였다. ‘세계진미’의 쌀수량성은 2006부터 2008년까지 3년간 실시한 지역적응시험 보통기 다비재배(6개소)에서 7.01 MT/ha로‘다산벼’ 대비 8% 증수 되었다. ‘세계진미’의 적응지역은 중부 및 영호남 평야지이다.
Abstract
Agriculture is being forced into marginally productive areas due to utilization of more land area for housing and industrial activities. Furthermore, climate changes also become a primary restriction factors for food security. To cope against these changes, a Tongil-type rice cultivar ‘Saegyejinmi’ derived from a cross of ‘Milyang160 (Areumbyeo)’ and ‘Yongjubyeo (Suwon333)’ which is high yielding and good eating quality as well as multiple deasease resistant was developed at Department of Functional Crops, NICS, RDA in 2008. The pedigree name of ‘Saegyejinmi’ is YR20798-6-3-1, which was designated as ‘Milyang 223’ later. Heading date of ‘Saegyejinmi’ is August 17 as mid-late ecotype unlike other early ecotype of Tongil-type cultivars. The culm length of ‘Saegyejinmi’ was 82 cm which is 10 cm higher than that of ‘Dasanbyeo’. ‘Saegyejinmi’ shows multiple resistances to leaf blast, all races of bacterial blight (K1, K2, K3, K3a), and rice stripe viruses. It is susceptible to plant hoppers. The taste and texture of cooked ‘Saegyejinmi’ were similar or even higher compared to that of japonica grains. In the local adaptability test, the potential milled rice yield of ‘Saegyejinmi’ was about 7.01 MT/ha at 18 kg/10a of nitrogen fertilizer level. ‘Saegyejinmi’ is suitable for mid and southern plains of Korea.
