Mild taste and early maturing red onion cultivar ‘Eumjinara’

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±49.1 g/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 μ g/g FW and 556.11 μ g/g FW, respectively.
