Abstract
‘Aram’ is a soybean cultivar developed for soy-sprout. It was developed from the crossing of ‘Bosug’ (Glycine max IT213209) and ‘Camp’ (G. max IT267356) cultivars in 2007. F1 plants and F2 population were developed in 2009 and 2010. A promising line was selected in the F5 generation in 2011 using the pedigree method and it was evaluated for agronomic traits, yield, and soy-sprouts characteristics in a preliminary yield trial (PYT) in 2012 and an advanced yield trial (AYT) in 2013. Agronomic traits and yield were stable between 2014 and 2016 in the regional yield trial (RYT) in four regions (Suwon, Naju, Dalseong, and Jeju). Morphological characteristics of ‘Aram’ are as follows: determinate plant type, purple flowers, grey pubescence, yellow pods, and small, yellow, and spherical seeds (9.9 g 100-seeds-1) with a light brown hilum. The flowering date was the 5th of August and the maturity date was the 15th of October. Plant height, first pod height, number of nods, number of branches, and number of pods were 65 cm, 13 cm, 16, 4.5, and 99, respectively. In the sprout test, germination rate and sprout characteristics of ‘Aram’ were comparable to that of the ‘Pungsannamulkong’ cultivar. The yield of ‘Aram’ was 3.59 ton ha-1 and it was 12% higher than that of ‘Pungsannamulkong’ in southern area of Korea. The yield of ‘Aram’ in the Jeju region, which is the main region for soybean sprout production, was 20% higher than that of ‘Pungsannamulkong’. The height of the first pod and the tolerance to lodging and pod shattering, which are connected to the adaptation to mechanized harvesting, were higher in ‘Aram’ compared to those in ‘Pungsannamulkong’. Therefore, the ‘Aram’ cultivar is expected to be broadly cultivated because of its higher soybean sprout quality, and seed yield and better adaptation to mechanized harvesting.
