초록
To improve their income, farmers should cultivate sorghum varieties with high productivity, short breeding period, and easy double cropping. To increase purchases by consumers, the sorghum variety must have health-related functions. To meet these demands, the 'Cheongpung' variety has been raised through net separation from the traditional species of the Chungbuk region as a sorghum variety that can be harvested by machine, have the highest yield in the country, and have the most abundant antioxidant content. The seed coat of ‘Cheongpung’ was reddish-brown, and had the characteristic of early maturation; it required only 107 days from sowing to harvest. Its culm length was 89 cm, the smallest among domestic cultivated varieties. It could also be harvested by machine without difficulty. Compared with the ‘Hwanggeumchal’ variety, the number of ear per plant in ‘Cheongpung’ was approximately 1.3, but each ear piece weighed 66.2 g, weighing 3.8 g, and the thousand-grain weight was 1.4 grams higher than the rough-grain weight. A local adaptation test in five regions nationwide for two years led to a ‘Cheongpung’ yield of 359 kg/10a, which was the highest among domestic cultivated varieties. In addition, the polyphenol content of ‘Cheongpung’ was 29% higher than that of ‘Hwanggeumchal’. As a result of this research, ‘Cheongpung’ has been registered as a variety (grant number No. 7717) in the Korea Seed and Varieties Service in 2019, since it was filed for breed protection in 2017.
Abstract
To improve their income, farmers should cultivate sorghum varieties with high productivity, short breeding period, and easy double cropping. To increase purchases by consumers, the sorghum variety must have health-related functions. To meet these demands, the 'Cheongpung' variety has been raised through net separation from the traditional species of the Chungbuk region as a sorghum variety that can be harvested by machine, have the highest yield in the country, and have the most abundant antioxidant content. The seed coat of ‘Cheongpung’ was reddish-brown, and had the characteristic of early maturation; it required only 107 days from sowing to harvest. Its culm length was 89 cm, the smallest among domestic cultivated varieties. It could also be harvested by machine without difficulty. Compared with the ‘Hwanggeumchal’ variety, the number of ear per plant in ‘Cheongpung’ was approximately 1.3, but each ear piece weighed 66.2 g, weighing 3.8 g, and the thousand-grain weight was 1.4 grams higher than the rough-grain weight. A local adaptation test in five regions nationwide for two years led to a ‘Cheongpung’ yield of 359 kg/10a, which was the highest among domestic cultivated varieties. In addition, the polyphenol content of ‘Cheongpung’ was 29% higher than that of ‘Hwanggeumchal’. As a result of this research, ‘Cheongpung’ has been registered as a variety (grant number No. 7717) in the Korea Seed and Varieties Service in 2019, since it was filed for breed protection in 2017.
