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’. (Registration No. 7717)

To satisfy the health needs of consumers and enhance the yields of producers, a grain crop ‘Cheongpungchal’ (Panicum miliaceum L.) with many common names, including proso millet, was collected from a landrace in Danyang, Chungbuk province and developed using a pure-line selection method. ‘Cheongpungchal’, which has a brown seed coat, has characteristics of a medium-maturing variety, requiring 102 days from sowing to harvesting. The variable growth characteristics included a stem length of 155 cm on average and length of ears 38.4 cm on average. As for the yield-related characteristics, the average number of spikes per plant was 3.8, the ear weight per plant was 11.8 g, and the rough millet thousand-grain weight averaged 5.17 g. The results of a regional adaptation test in 5 regions of Korea for three years revealed the yield of ‘Cheongpungcha’l to be 38% higher than that of the ‘Hwanggeumgijang’ variety, representing the best yield from among existing varieties. The total polyphenolic content of ‘Cheongpungchal’ was 32% higher than that of the ‘Hwanggeumgijang’ variety, and the antioxidant activity was 63% greater than that of ‘Hwanggeumgijang’. As a result of this research, ‘Cheongpungchal’ has been registered as a variety (grant number No. 6964) with the Korea Seed and Varieties Service in 2018 following filing for breed protection in 2016.

‘Geumsilchal’ is a Proso millet (Panicum miliaceum L.) variety developed and registered by the Department of Southern Area Crop Science, NICS, RDA, in 2014. This variety was developed through pure line selection from K131247. ‘Geumsilchal’ was an erect type medium-maturing variety. Its growing period was 104 days when it was seeded on May 15, and 94 days when it was seeded on July 15 in Milyang, Korea. The culm length of ‘Geumsilchal’ was about 123 cm, which was 13 cm longer than that of the standard variety ‘Hwanggeumgijang’. ‘Geumsilchal’ was tolerant to lodging in the field because of its wide column width and erect plant type. The panicle type was droopy and its length was about 23 cm. Seed grain and dehusked grains were yellow, and the endosperm characteristic was glutinous. The yield potential of ‘Geumsilchal’ was about 2.41 ton ha^-1 in regional yield trials from 2013 to 2014 and was 27% higher than that of the standard variety ‘Hwanggeumgijang’ (Variety registration No. 6247).

A mungbean cultivar ‘Sanpo’ (Vigna radiata (L.) Wilczek) was derived from the cross between SM9710-3B-7 and Jangannogdu at the Jeollanamdo Agricultural Research and Extension Services (JARES) in 2012. ‘Sanpo’ has erect growth habit, green hypocotyls, heart leaflet, dull green seed surface, and black and straight pod when matured. The stem length of ‘Sanpo’ were 71㎝, which was 5㎝ longer than check cultivar ‘Owool’. The pods number per plant, the seeds number per pod, and the seed weight of ‘Sanpo’ are similar to check cultivar. It has field resistance to cercospora leaf spot, mungbean mottle virus, and powdery mildew. In addition, ‘Sanpo’ has high lodging resistance. The hard seed rate of ‘Sanpo’ was 2.4%, which was 0.8%point lower than check cultivar. The sprout yield ratio of ‘Sanpo’ was 8.26 times, which was 10% (77%point) more than check cultivar. The average yield of ‘Sanpo’ was 1.62ton/㏊, which was 14% more than the check cultivar ‘Owool’. (Cultivar registration number: 5250)
