: 'Soim' is a new leaf vegetable perilla (Perilla frutescens var. japonica Hara) variety developed from the cross between Ipdeulkkae1 and YCPL173 at the Department of functional crop, NICS, RDA, in 2009. Uniform perilla leaf size is one of the most important characteristics for reduction of manpower. To harvest uniform perilla leaf, farmers cultivate just main stem and remove all branches. The next harvest leaves grow well, so farmers gain high leaf yielding and efficiency of harvest leaf. 'Soim' grows vigorously and yields high quality leaf with larger size of the next harvesting leaves compared with a check cultivar, 'Ipdeulkkae1'. For the leaf production, 'Soim' is adaptable to whole arable land in South Korea. However, because of its late maturity, seed production cultures need rain shield. No. of breeder's right: 4387

'Socheong 2' was selected from the cross between 'Milyang78' and 'Peking'. The preliminary, advanced and regional yield trials for evaluation and selection of this variety were carried out from 2005 to 2009. It has determinate growth habit, white flower, brown pubescence, black pod color, black seed coat, green cotyledon, elongated flattened seed shape, oval leaf shape and small seed size (12.2 grams per 100 seeds). And it has the same maturity as the check cultivar Cheongjakong. 'Socheong 2' has better seed quality than that of the check cultivar in isoflavone contents (2,031 ㎍/g), and it has good adaptability for 'Cheongkugjiang' and soybean malt. It also has been identified to have resistance to soybean mosaic virus symptom (SMV) which was the troublesome soybean diseases. The average yield of 'Socheong 2' was 2.00 ton per hectare in the regional yield trials carried out in five locations of Korea among seven from 2007 to 2009, which was 7 percent higher than that of the check cultivar 'Cheongjakong'.
