초록

북한 콩 22 품종의 개화기 특성을 평가하기 위하여 2017년부터 2019년 3년간 고려대학교 실험농장에서 5월 31일, 6월 19일, 6월 30일, 7월 3일, 7월 4일의 파종기에 따른 개화기와 개화일수를 조사하였고, 이를 이용하여 개화기 군을 분류하여 개화기 반응을 분석하였다. 1. 5월 31일 파종한 한국 조생종인 '연풍콩'의 개화기는 7월 18일, 개화일수 48일 보였으며, 중만생종 '대원콩'은 7월 30일의 60일이었다. 2. 5월 31일 파종기에서 개화기가 '연풍콩'보다 빠른 북한 품종의 개화기는 7월 2일~15일로 분포하였으며, 'Brekkhat'을 포함한 8개 조생종 품종이 분류되었다. 3. 5월 31일 파종기에서 '대원콩'과 비슷하거나 늦은 북한 품종의 개화기는 7월 24일~30일로 분포되었으며, 'Chang Dan Bac Mok'을 포함한 12품종을 중·만생종 품종으로 분류하였다. 4. 콩 품종의 개화기 조만성은 년차 간 또는 파종기 간 차이가 나타나지 않았으며, 품종의 개화기 군 분류에 영향을 미치지 못하였다. 5. 한국 조생종 '연풍콩'과 중만생종 '대원콩'의 개화기를 기준으로 북한 콩 품종의 개화기를 6개 군으로 분류하였다. 6. 북한 중·만생종 콩 품종은 모두 '감광성 중·만생종'으로 분석되었으며, 조생종 품종의 경우, '감온성 조생종'과 '감광성 조생종'의 2 형태로 분류되었음을 제시하였다.

This study was conducted to evaluate the flowering characteristics of 22 soybean (Glycine max Merrill) varieties of North Korea and classify the flowering group by the flowering date. The flowering date and the days required for flowering with the different planting times on May 31, June 19, June 30, July 3, and July 4 were investigated at the agricultural experimental field of Korea University for three years from 2017 to 2019. The flowering date and the days for flowering of "Yeonpungkong", an early maturing soybean cultivar of Korea, were July 18 and 48 days, respectively, at the planting time of May 31, those of "Daewonkong", a mid-late maturing cultivar, were July 30 and 60 days, respectively. Based on the flowering dates of "Yeonpungkong" and "Daewonkong", North Korean soybean varieties were classified into six flowering groups. Eight North Korean soybean varieties had the flowering dates earlier than "Yeonpungkong", including "Brekkhat" classified into the early flowering group. The range of flowering date was July 2 to 15 at planting time of May 31. Twelve North Korean soybean varieties had flowering dates similar to or later than "Daewonkong", including "Chang Dan Bac Mok" classified into the mid-late flowering group. The range of flowering date was July 24 to 30 at the planting time of May 31. For flowering response to environmental stimulus, all of the mid-late flowering varieties of North Korea responded to "photosensitive or day-length" for flowering reaction. The early flowering varieties were divided by "photosensitive" response and "temperature" response variety.
