Abstract

'Nampungchal' is a Sorghum bicolor L. developed and registered by Department of Sothern area crop science, NICS, RDA in 2012. This variety was developed through pure line breeding method from 'Namhae' landrace. 'Nampungchal' is a medium maturing variety having 68 days from planting to heading of sorghum in Miryang, Korea. The plant is pigmented (purple), the glumes and grains are red-brown with waxy endosperm. The panicle has less compact shape and the length is 23 cm. The grain yield of 'Nampungchal' is about 2.28MT/ha that is higher 9%, when compared with standard variety 'Hwanggeumchal'. Culm length and width are about 142 cm and 20.2 cm, respectively. It could be reduce the lodging problem by thicker stems and also adapted to mechanized cultivation. 'Nampungchal' does produce high quantities of polyphenol and tannin contents with DPPH radical scavenging activity in pigmented testa. The object of this breeding program is improvement for mechanized production with high yield potential, lodging resistant, and responsive to favorable environmental conditions.

'남풍찰'은 경남 남해에서 수집된 재래집단을 기본으로 하여 분리육종법을 통해 국립식량과학원에서 2012년 육성된 신품종으로 주요특성과 수량성을 요약하면 다음과 같다. 출수기는 표준 품종인 '황금찰'보다 보통기 재배에서는 8일 정도 늦은 중생종으로 출수일수는 73일 정도이다. 간장은 142cm 정도로 황금찰에 비해 약간 크고, 도복에 강한 특성을 나타낸다. 이삭은 밀수형이며 이삭길이는 23cm이다. 영과색이 적갈색이며, 배유의 아밀로스 함량이 5.7%로 찰수수에 해당하며, 날알의 무기성분 중 칼슘 19.8 mg/100g, 마그네슘 201.2 mg/100g, 칼륨 619.6 mg/100g으로 비교적 함량이 높으며 DPPH, ABTS 소거 항산화활성 역시 '황금찰'에 비해 높은 특성을 가지고 있다. 수량은 지역적응 시험 보통기재배 평균 2.28 MT/ha로서 표준품종 보다 9% 정도 증수되는 다수성이고, 내도복 및 내재해 품종으로 기계화 재배에 유리한 우수한 품종이다(Fig. 2).
