초록

북한 주요 벼 재배지역의 재배기간 및 환경 적응 벼 품종을 선정하기 위하여, 13 지역의 조기이앙한계기~출수기 기간 중 기온과 일장 변화 조건에서 남한, 북한, 중국 동북 3성의 40개 품종을 공시하여 출수 반응 차이를 검토한 결과는 다음과 같다. 1. 북한 주요 벼 재배지역 환경에서 출수가 가장 빨랐던 품종은 지역에 따라 중국 동북 3성 품종 중 Kenjiandao3, Nongdae3과 북한 품종 중 올벼1, 올벼2, 선봉9로 나타났으며, 동해안 남부의 장전과 원산에서는 남한 품종인 조운이 가장 빠른 수준을 보였다. 2. 시험 대상 13 지역 중 안전출수한계기까지 출수한 품종은 해주와 사리원 환경에서 34개로 가장 많았고, 원산, 장전, 수풍, 용연에서 16~17개로 가장 적었다. 3. 북한 서남부 평야지에 위치한 개성, 해주, 사리원, 남포, 평양 조건에서는 남한 품종 중 일부 중생종과 중만생종까지 안전출수한계기 이내에 출수하였다. 4. 서남부 평야지 중 해발이 가장 높은 신계와 중서부 평야지의 안주, 구성, 신의주에서는 남한 조생종 14 품종 중 10~11개가 안전출수한계기까지 출수하였다. 5. 서남부 평야지 중 기온이 낮아 조기이앙한계기~안전출수한계기 기간이 짧은 용연, 동해안 남부의 장전과 원산환경에서는 남한 조생종 중 출수가 빠른 6~8 품종만 안전출수한계기까지 출수하였다. 6. 출수소요일수는 모든 지역 사이에 고도로 유의한 정의 상관을 보였으나, 지역 환경에 따른 출수소요일수 변화의 품종간 상관은 유의하지 않은 경우가 많았다. 7. 시험 대상 지역 환경의 변화에 따른 출수소요일수 반응은 군집분석의 유사도 65% 수준에서 ① 진부올, 산호미, 선봉9, 진부, ② 백일미, 조품, 운광, 조평, 조생흑찰, 조운, 오대, 해들, 온포1, 원산69, ③ 올벼1, 올벼2, Longdao5, Jijing88. Kenjiandao3, 평도15, Wuyoudao, ④ 아세미, 진미, 평도5, 평양21, 평양43, ⑤ 길주1, Nongdae3, ⑥ 진옥, 소비, 하이아미, 대보, 신보, 선품, 알찬미, 삼광, 호품, ⑦ 청아, 새누리, 청품의 7개 군으로 구분되었다.

The heading responses of rice varieties that originated from South Korea, North Korea, and northern China were examined under the temperature and day-length conditions of 13 major rice production areas in North Korea. Kenjiandao3 and Nongdae3 originated from China, Olbyeo1, Olbyeo2 and Sonbong9 from North Korea, and Joun from South Korea demonstrated the earliest heading stage depending on the regional environment. Out of 40 rice varieties, 34 reached the heading stage within the regional safe marginal heading date (SMHD) under Haeju and Sariwon environmental conditions, while 16 to 17 varieties reached the heading stage under Wonsan, Changjon, Supung, and Yongyon environmental conditions. Some middle and mid-late maturing varieties that originated from South Korea reached the heading stage within the SMHD under the temperature and day-length conditions of Kaesong, Haeju, Sariwon, Nampo, and Pyongyang that are located in the west-southern plain. The majority of early maturing varieties, but not the middle or mid-late ones, reached the heading stage within the SMHD under the environmental conditions of Singye, Anju, Kusong, and Sinuiju. Only a few early maturing varieties demonstrated the heading stage within the SMHD under Yongyon, Changjon, and Wonsan environments. The number of days to heading was highly positively correlated among all regions; however, it was not consistent among the rice varieties. The 40 rice varieties that had been tested were classified into seven groups according to their heading responses to the temperature and day-length variations of the 13 regional conditions at 65% similarity level in cluster analysis.
