A New Soybean Variety, ‘Joongmo 3009’ with Green Cotyledon, Black Seed Coat, Disease Tolerant, and High Yield

Abstract

A new soybean variety, 'Joongmo 3009' (Milyang 222) was developed at the National Institute of Crop Science (NICS) in 2012. 'Joongmo 3009' was released by pedigree selection from the cross between 'Cheongja 2(Milyang 121)' and 'Daemangkong'. It has determinate growth habit, white flower, brown pubescence, brown pod color, green seed coat, green cotyledon, spherical seed shape, oval leaf shape and large seed size (29.3 grams per 100 seeds). It was late 16 days in maturing date than the check cultivar 'Cheongjakong'. The average yield of 'Joongmo 3009' was 2.91 ton per hectare, which was higher 36 percentage than the check variety, in the regional yield trials carried out in three adaptable locations of Korea from 2010 to 2012. The number of breeder's right is '5474'

Identification of New Isolates of Phytophthora sojae and Selection of Resistant Soybean Genotypes

“…Five genotypes, including Taecheong, were only resistant to isolate GJ3053, while all differentials were susceptible to the GJ3053 ( Table 2 ), suggesting that they may possess unknown Rps alleles or genes that were not included in the differentials. Cheongja2 is the parental line of Jungmo3009 and Taecheong ( Baek et al, 2004 ; Han et al, 2016 ; Seo et al, 2020 ). Cheongja2 was developed from crosses between Milyang70 and Ilpumgeomjeong.…”
