Abstract

Red onion cultivar 'Eumjinara' with mild taste and early maturation was developed in 2013 by the Allium vegetable crop research team, National Institute Crop Science, Rural development Administration (RDA). 'Eumjinara' was originally selected from red onion breeding line, 'IS1115', It was preliminarily selected and designated 'Mon21-31-3' and advanced yield trial was performed from 2008 to 2009. Regional yield trial test was conducted in six regions from 2010 to 2012. Foliage morphology and leaf color were similar to those of a check cultivar, 'Cheonjujeok', but its shape was comparatively broad ovate. Foliage of 'Eumjinara' lodged seven days earlier than check cultivar on May 31 and the average bulb weight ($234{\pm}49.1g/bulb$) was also higher than that of check cultivar. The new cultivar was relatively resistant to clod hardness and downy mildew infection in the field condition. Average yield of 'Eumjinara' in three-year the regional yield trials was 6,999 kg/10a. The total soluble solid contents and quercetin concentrations were $41.43{\mu}g/g$ FW and $556.11{\mu}g/g$ FW, respectively.

'엄지나라'는 일반 자색양파 품종에 비해 숙기가 다소 빠른 품종이다. 2000년도에 수집한 'IS1115'에서 2002년에 계통 분리하여 육성하였다. '목포20호'로 명명하여 2008년부터 2009까지 무안에서 생산력검정을 하고 2010년부터 2012년까지 3년 동안 무안 등 6개소에서 지역적응성검정을 하였다. 엄지나라의 도복기는 5월31일로 대비품종 보다 7일 빠르고 추대와 분구가 적고 구형은 편구형이다. 내한성과 노균병에 내성이 있고 당도와 당 함량은 대비품종과 비슷하였다. 엄지나라 Quercetin류의 총 함량은 $556.11{\mu}g/g$으로 대비품종 보다 높았고 특히 QDG와 QMG가 많았다. 수량성은 무안 등 6개 지역에서 수행한 지역적응시험 결과 '엄지나라'의 10a당 평균 수량은 6,999kg으로 '천주적' 대비 12% 높았으며 특히, 무안, 안동, 단양에서 각각 31%, 15%, 28% 증수되었다.
