  • Ten samples were collected from soft rotted ornamental foliage plants, that were cultivated in the vinyl-houses in Taejeon, Yeoju, Seongnam, Kimhae and Cheju during 1998 to 1999. Studies on morphological, cultural, physiological and pathological characteristics indicated that the bacteria from Begonia heimalis, Saintpaulia sp. and Clivia miniata were Erwinia carotovora subsp. carotovora, E. carotovora subsp. carotovora the first description of bacteria which caused bacterial soft on Begonia heimalis, Saintpaulia sp., and Clivia miniata in Korea.

  • Climate change, increased extreme weather and climate events, and rapidly changing socio-economic environment threaten agriculture and thus food security of our society. Therefore, it is urgent to shift from conventional farming to smart agriculture using big data and artificial intelligence to secure sustainable growth. In order to efficiently manage plant diseases through smart agriculture, agricultural big data that can be utilized with various advanced technologies must be secured first. In this review, we will first learn about agrometeorological big data consisted of meteorological, environmental, and agricultural data that the plant pathology communities can contribute for smart plant disease management. We will then present each sequential components of the smart plant disease management, which are prediction, monitoring and diagnosis, control, prevention and risk management of plant diseases. This review will give us an appraisal of where we are at the moment, what has been prepared so far, what is lacking, and how to move forward for the preparation of smart plant disease management.

  • 배추무사마귀병 저항성 집단을 육성하기 위하여 총 305점의 배추유전자원을 수집(농촌진흥청 유전자원과, 180점; 미국 Germplasm Resources International Network, USDA, 37점; CPRODLO Bra-dB, Wagenningen 59점; 국내외 종묘회사, 29점) 하였다. 14점의 재배종은 배추무사마귀병에 대해 높은 저항성을 보였으면 대부분이 일대 잡종으로 CR계 품종이었다. CR계 일대잡종 18품종으로 배추무사마귀병에 저항성 집단을 만들기 위하여 자식과 방임수분으로 각각을 교배하였다. 2년간 포장시험을 하여 배추무사마귀병에 저항성인 성숙모본 128개체를 선발하였고 선발된 개체들은 배추무사마귀병에 대한 저항성집단을 육성하는데 식물재료로 이용되었다.(중략)
