초록

강원지역 주요 농업지대별 알맞은 최고품질의 중만생종 벼 품종을 선발하고자, 농촌진흥청에서 최근 육성한 중만생종 8개 품종을 대상으로 2013년부터 2014까지 2년간 춘천, 강릉, 철원 등 3개 지역에서 수행한 결과를 요약하면 다음과 같다. 1. 벼 생육기간 동안 평균기온은 2013년과 2014년 모두 춘천에서 평년대비 $0.6{\sim}1.1^{\circ}C$, 강릉 $1.0{\sim}1.3^{\circ}C$, 철원 $0.1{\sim}0.7^{\circ}C$ 높았다. 등숙기 강수량은 2013년에 춘천에서 평년대비 52.5 mm 많았고 2014년에는 176.4 mm 적었으며, 강릉은 2013년에 103.1 mm 적었고 2014년에는 42.9 mm 많았다. 반면 철원은 2013년과 2014년 모두 225.9~322.7 mm 가량 적었다. 2. 등숙기 일조시간은 2013년에 춘천, 강릉 및 철원에서 각각 평년대비 142, 108 및 94시간 많았고, 2014년에는 춘천, 강릉에서 20~21시간, 철원에서는 82시간 많았다. 3. 2년간 평균 10a당 백미수량은 춘천에서 삼광벼와 대보벼 594 kg, 진수미벼 578 kg을 보였고, 강릉에서는 대보벼 555 kg, 호품벼 554 kg, 칠보벼 546 kg, 그리고 철원에서는 대보벼 504 kg, 하이아미벼 489 kg로 다른 품종들에 비하여 다소 높은 수량을 보였으나 품종간 유의적인 차이는 없었다. 4. 완전미율은 춘천에서 하이아미벼 95.6%, 진수미벼 94.7%, 미품벼 94.2%로 다른 품종에 비하여 뚜렷하게 높았고, 싸라기율과 심복백미율도 다소 낮았다. 강릉에서는 호품벼, 하이아미벼, 삼광벼의 완전미율이 85.2~88.3%의 범위로 다른 품종에 비하여 다소 높았으나, 고품벼를 제외한 나머지 품종간에 유의적인 차이는 없었다. 싸라기율은 하이아미벼, 삼광벼, 미품벼에서 7.5~8.5%의 범위로 다소 낮았고 윤기치는 미품벼에서 78로 다른 품종에 비하여 유의적으로 높았다. 철원에서 완전미율은 대보벼가 89.2%로 고품벼와 하이아미벼에 비하여 유의적으로 높았으며, 싸라기율, 심복백미 및 식미치 등은 품종간 뚜렷한 차이가 없었다. 이상의 결과를 종합해 볼 때, 강원지역 주요 농업지대별 적응성이 우수한 최고품질의 중만생종 품종에 있어서 평야지 춘천은 삼광벼, 하이아미벼 및 진수미벼, 동해안지 강릉은 대보벼와 칠보벼, 그리고 중간지 철원에서는 대보벼가 재배안전성과 환경적응성이 가장 우수하였다.

Rural Development Administration has recently developed mid-late maturing rice cultivars with high quality. This study was conducted to select suitable mid-late maturing rice cultivar in major cultivation areas of Gangwon Province among domestic breeding cultivars for 2 years from 2013 to 2014. The average air temperature during the experiment in 2013 and 2014 was higher $0.6{\sim}1.1^{\circ}C$ in Chuncheon, $1.0{\sim}1.3^{\circ}C$ in Gangreung, and $0.1{\sim}0.7^{\circ}C$ in Cheolwon than normal year. Precipitation in ripening period was higher 52.5 mm in 2013, but lower 176.4 mm in 2014 than normal year in Chuncheon, lower 103.1 mm in 2013 and higher 42.9 mm in 2014 in Gangreung, lower 225.9~322.7 mm in Cheolwon. Duration of sunshine in ripening period was higher 142 hours in Chuncheon, 108 hours in Gangreung, and 94 hours in Cheolwon than normal year in 2013, higher 20~21 hours in Chuncheon and Gangreung, and 82 hours in Cheolwon than normal year in 2014. Milled rice yield of 'Samgwangbyeo' and 'Daebobyeo' was 594 kg per 10a, and 578 kg for 'Jinsumibyeo' in Chuncheon in plain area. For Gangreung in east coastal area, the yield of 'Daebobyeo' was 555 kg per 10a, 'Hopumbyeo' was 554 kg, and 'Chilbobyeo' was 546 kg. For Cheolwon in mid-mountainous area, the yield was 504 kg per 10a for 'Daebobyeo' and 489 kg for 'Haiamibyeo'. But there was no difference in milled rice yield among cultivars tested in the study at each area. Head rice ratio of 'Haiamibyeo', 'Jinsumibyeo', and 'Mipumbyeo' in Chuncheon was 94.2~95.6% higher than the other cultivars. In Gangreung head rice ratio of 'Hopumbyeo', 'Haiamibyeo', and 'Samgwangbyeo' were 85.2~88.3% but there was no difference among cultivars except 'Gopumbyeo' and broken rice ratio of 'Haiamibyeo', 'Samgwangbyeo', and 'Mipumbyeo' were low as 7.5~8.5% and palatability of 'Mipumbyeo' was higher than the other cultivars. Head rice ratio of 'Daebobyeo' was the highest as 89.2% and there was no difference in broken and chalky rice ratio and palatability among cultivars in Cheolwon. Considering rice yield and quality in major cultivation areas of Gangwon Province, suitable mid-late maturing rice cultivars were 'Samgwangbyeo', 'Haiamibyeo', and 'Jinsumibyeo' in Chuncheon, 'Daebobyeo' and 'Chilbobyeo' in Gangreung, and 'Daebobyeo' and 'Haiamibyeo' in Cheolwon. The results obtained in the study imply that the selected cultivars with high yield and quality and suitability to Chuncheon, Gangreung, and Cheolwon, respectively could be recommended to rice cultivating farmers in the regions with high priority.
