The sorghum (Sorghum bicolor (L.) Moench) variety ‘Noeulchal’ was developed and registered by the Department of Southern Area Crop Science, National Institute of Crop Science, in 2019. This variety was developed from the cross between ‘RTx2907’, with white grain, and ’Sodamchal’, with brown grain and semi-dwarf traits. The yield performance of ‘Noeulchal’ was 3.71 MT/ha in a local adaptability test run for two years. It had a culm length of 93 cm, which is 11 cm longer than that of ‘Sodamchal’, a panicle length of 29 cm, a culm 22 mm thick, and a panicle exsertion of 9 cm. It could reduce the lodging problem experienced with current cultivars, and is also adapted to mechanized cultivation. ‘Noeulchal’ has a waxy endosperm with 3.2% amylose and contained high levels of rapidly digestible starch. The rapidly digestible starch with gluten-free flours could contribute to the development of foods with different properties (Registration No. 9105).

A soybean cultivar for sprout, ‘Joyang 1’ was developed at the National Institute of Crop Science (NICS) in 2010. ‘Joyang 1’ (Iksan67) was released by pedigree selection from the cross between high yielding ‘Pungsannamulkong’ and ‘Suwon187’ tolerant to lodging and disease. It has purple flower, lanceolate leaf, grey pubescence and small yellow seed. Weight of hundred seed is 11.6gram. Maturing date of ‘Joyang 1’ is ten days earlier than check cultivar, ‘Pungsannamulkong’. ‘Joyang 1’ is resistant to bacterial pustule and shattering. It have similar tolerance to root rot and seed spot to check cultivar. It shows high germination ratio, less abnormal germination and hard seed. Sprout yield also 11 percent higher than check cultivar. The average seed yield of ‘Joyang 1’ was 3.03 ton per hectare in the regional yield trials (RYT) carried out for three years from 2008 to 2010 which was 3 percent higher than the check cultivar. The number of breeder’s right is ‘4900’.
