초록

고구마는 우리나라와 같은 온대지역에서 개화(開花)가 잘 되지 않고 자가부화합성(自家不和合性)으로 알려져 있지만 자가화합성(自家和合性) 품종도 있으며 품종간(品種間)에 교잡부화합성(交雜不和合性)이 존재한다. 그러나 국내에서는 지금까지 이러한 특성(特性)들이 연구되지 않아 육종효솔(育種效率)이 매우 낮다. 따라서 본 연구는 고구마 교잡육종(交雜育種) 효솔증진(效率增進)을 위한 기초자료로 활용하고자 국내에서 육성된 33개 품종의 개화성(開花性)을 조사하였다. 1. 자근(自根) 개화성(開花性)은 10~10.5시간의 일장(日長)에서 신미(新美) 등 14개 품종, 10.5~12시간(時間)의 일장(日長)에서는 홍미(紅美) 등 3개 품종만이 다소 개화되었고 그 이외의 품종들은 개화(開花)되지 않았으며, 12~14시간의 일장(日長)에서 개화되는 품종은 없었다. 2. 나팔꽃 대목(臺木)에 접목(接木)하였을 때는 자근상태(自根狀態)에서 거의 개화가 안되었던 품종들이 모두 개화되었고, 일장처리(日長處理) 방법에 있어서는 접목(接木)된 식물체(植物體)를 암실(暗室)로 이동시키는 방법에 의해 인위적(人爲的)으로 10시간의 단일처리(短日處理)를 하는 것보다 동계(冬季) 자연단일(自然短日) 상태(狀態)에서 개화성(開花性)이 더 증진되었다. 3. 품종별(品種別)로는 목계(木系)1호(號) 등 8개 국내품종은 접목(接木)과 단일상태(短日狀態)에서도 개화성(開花性)이 양호(良好)하지 못하였고 그 이외의 품종들은 개화성(開花性)이 양호(良好)하였다. 4. 화기특성(花器特性)은 조사품종 전체평균 화경(花梗)길이 $56.2\pm21.2\;mm$, 화경폭(花梗幅) $3.2\pm0.5\;mm$, 소화경(小花梗)길이 $6.8\pm2.1\;mm$, 소화경폭(小花梗幅) $2.4\pm0.3\;mm$, 암술길이 $19.3\pm1.7\;mm$, 최장(最長)수술길이 $20.2\pm2.7\;mm$, 최단(最短)수술길이 $14.6\pm1.9\;mm$로서 화경(花梗)길이를 제외하고는 품종간(品種間)에 거의 차이가 없었다. 화주(花柱), 주두(柱頭) 및 화분(花粉)의 색(色)은 대부분의 품종이 백색(白色)이었으나 건미(健美) 등 2개 품종은 화주(花柱)가, 선미(善美) 등 4개 품종은 주두(柱頭)가 옅은 분홍색(粉紅色)이었고, 자방(子房)은 모든 품종이 옅은 갈색(褐色)이었다. 화관폭(花冠幅)은 $36.7\pm6.0\;mm$, 화통폭(花筒幅)은 $12.8\pm1.5\;mm$, 화관(花冠)길이는 $40.2\pm6.5\;mm$이었고, 화관(花冠) 및 화통(花筒)의 색은 모든 품종이 분홍색(粉紅色)이었으며, 화분직경(花粉直徑)은 $131\pm1.5\;{\mu}m$였다.

Korean sweetpotato, Ipomoea batatas, varieties were examined for their flowering response as a fundamental research to improve breeding efficiency by hybridization of this crop. Under 10.0~10.5 hours short day condition, self-rooted plants of three varieties such as Shinmi, Hongmi and Hwangmi flowered sparsely or moderately, and those of fourteen varieties including Eunmi flowered very sparsely. Under 10.6~12.0 hours day length condition, self-rooted plants of three varieties such as Shinmi, Hongmi and Hwangmi flowered very sparsely. Under the day length longer than 12 hours, none of the tested plants flowered. In all the sweetpotato plants grafted on morning glory, flowering occurred with varying degrees by varieties and day lengths. Under 10.0~10.5 hours day length, thirty two varieties including Hongmi flowered moderately or profusely, and one variety such as Mokgye 1 flowered sparsely. Under 10.6~12 hours day length, twenty three varieties including Sinchunmi flowered moderately or profusely, nine varieties including Jeungmi flowered sparsely, and Mokgye 1 didn't flower at all.
