A New Soybean Cultivar for Sprout with Small Seed Size, Disease Resistance and High Yield, “Bosug”

A new sprout-soybean cultivar, “Bosug” was developed from the cross between Namhaekong and Camp. by the soybean breeding laboratory of the National Honam Agricultural Experiment Station (NHAES) in 2003. The preliminary, advanced, and regional yield trials for evaluation and selection were carried out from 2000 to 2003. Bosug has a semi-determinate growth habit, purple flower, grayish brown pubescence, brown hilum, and rhomboidal leaflet shape. The maturity date of Bosug is 4 days earlier than the check cultivar, Pungsan. It has a good seed quality for soybean-sprout. It has high isoflavone (3.891 μg/g) and amino acid (396 mg/g) contents in soybean-sprouts. And it has 100 seed weight being 8.6 g and resistance to lodging. It has also been identified to have resistance to soybean mosaic and necrotic symptom of soybean mosaic virus that are the troublesome soybean diseases. The average yield of Bosug was 2.62 ton per hectare in the regional yield trials for double cropping carried out for three years from 2001 to 2003 which was 7 percent higher than the check variety, Pungsan
