네모집날도래과의 Goerodes sinuatus (Martynov)와 바수염날도래과의 Psilotreta falcula Botosaneanu와 P. locumtenens Botosaneanu를 남한에서 처음으로 기록하였다. 사육에 의하여 Goerodes elongatus (Martynov)는 유충단계를 처음으로 밝혔고, 그간 혼동되었던 Psilotreta kisoensis Iwata 와 P. locumtenens Botosaneanu의 유충과 성충관계를 밝혔다.
1988년 북한의 4개 주요 지역(평양, 해주, 묘향산, 백두산)에서 헝가리 학술조사단에 의하여 채집된 표본을 이용하여 하루살이목의 분포상이 조사되었다. 조사의 결과 하루살이목의 12개 과에서 46종(미동정종 10종 포함)이 밝혀졌고, 그 채집지와 함게 목록을 작성하였다.
1986년 체코 학술조사단에 의하여 북한의 5개 지역(평양, 개성-해주, 묘향산, 금강산, 백두산)에서 하루살이가 집중적으로 채집되었다. 그 결과 59종(미동정종 13종 포함)의 하루살이가 확인되었고, 그 중 Labiobaetis atrebatinus(Eaton), Ephemerella(Serratella) ignita(Poda), E. (S.) zapetkinae(Bajkova), Ephemera sahalinensis Matsumura, Cinygmula kurenzovi Bajkova, Rhithrogena binotata Sinitshenkova, Metretopus borealis Eaton 및 Siphlonurus palaearcticus Tshemova는 한반도에서 처음으로 기록되는 종이다. 채집지의 일반적인 서식환경과 28개 채집지점의 미소서식처를 기술하였고, 어떤 종은 분포 특성 및 분류학적 변동을 논하였다.
Background : Recently, there is a urgent demand for development of new varieties with enhanced resistance to various biotic/abiotic stresses. In order to develop ginseng varieties with such traits, systematic breeding program and comprehensive field studies are prerequisite. Methods and Results : ‘Cheonmyeong' seeds were collected in 2008 from the farmer field of Buyeo. Physiological investigation and propagation were conducted from 2009 to 2011. It was given the name 'Eumseong No. 8 through the observed yield trial from 2012 to 2013 and local adaptability was carried out from 2014 to 2015. All phenotypes including agronomic characteristics, seed yield, and physiological response to biotic/abiotic stresses were investigated according to the ginseng GAP and UPOV guidelines. Yellow-red leaf and pink berry at maturing stage were observed. The time of emergence, flowering and berry maturity of the ‘Cheonmyeong’ were faster than those of ‘Chunpoong’. Stem length of ‘Cheonmyeong’ was shorter than that of ‘Chunpoong’, whereas stem diameter was thicker than that of ‘Chunpoong’. Main root length was shorter but main root diameter is thicker than that of ‘Chunpoong’. Number of seeds of ‘Cheonmyeong’ was fewer than that of ‘Chunpoong’ but 1,000-seeds weight and stratification rate were higher than those of ‘Chunpoong’. The yield performance of this variety was 661 kg/10 a in local adaptability test for two years, which is 22% higher than that of ‘Chunpoong’. ‘Cheonmyeong’ showed strong resistance to phytophthora blight, mulberry mealybug and nematode and moderate resistance to alternaria blight. ‘Cheonmyeong’ did almost not occur yellow spot of aerial part and rusty skin of root, show moderate resistance at high temperatures. Conclusion : Our study demonstrated that ‘Cheonmyeong’ is an ideal variety with heavier root weight and enhanced stress resistance and contribute will enhance biotic/abiotic stress resistance and increase the farmers' income.
