Abstract

The demand of sorghum is increasing since sorghum has significant and positive role in promoting nutrition and health of human beings; however, sorghum cultivated by farms is mostly a native variety having low genetic purity and low production, so it is necessary to improve the variety. Accordingly, the National Institute of Crop Science (NICS) developed "Donganme" that is non-glutinous and functional sorghum having antioxidant activity with higher yield potential. "Donganme" is the variety cultivated in 2012 through the breeding by the separation method from the foundation stock of 'CS-4 LOCAL COLLECTION' parceled out from the National Agricultural Genetic Resources Center. "Donganme" is a medium maturing variety, which takes the average of 71 days from the sowing date to the heading date, and the average of 120 days to the harvest. It has the culm length of 138 cm; the egg-shaped spikelets; dark red seeds, which are redder than those of the native variety, "Hwanggumchal." Since the number of the ears is 3 per plant, the advantage of tillers is mature at the same time; The average quantity of the regional adaptation test is 3.1 MT/ha, and it means the high-yielding ability. In addition, Donganme contains various functional components including polyphenols, flavonoids, etc.; its antioxidant activity is 42.0 mgTE/g and 30% higher than that of "Hwanggumchal." Unpolished grain's thousand-kernel weight is 26.8 g; the weight per plant is as heavy as 33.6 g; the lodging is stronger than that of "Hwanggumchal". Hwanggumchal has been cooked simply with rice due to its glutinous property, however, Donganme can be used more widely for processed food, such as bread, crackers, noodles, etc., due to its non-glutinous property. Moreover, its antioxidant activity can enhance the quality of those processed food.

국내 수수는 대부분 재래종을 재배하고 있어 유전적으로 순도가 높지 못해 품종개발이 필요하다. 이에 따라 국립식량과학원에서는 항산화 활성과 수량성이 높은 건강기능성 메수수 '동안메'를 육성하였다. '동안메'는 2009년 국립농업유전자원센터에서 분양받은 분양받은 'CS-4 LOCAL COLLECTION'을 기본집단으로 하여 분리육종법을 통해 2012년 육성된 품종이다. "동안메"는 파종 후 출수까지 평균 71일, 수확까지는 평균 120일인 중생종이다. 간장은 약 138 cm이고 이삭의 형태는 밀도가 높은 계란형이다. 받침껍질(영)색과 종실색은 짙은 갈색으로 표준품종인 "황금찰"보다 좀 더 진한 붉은색을 띈다. 한 주당 이삭수는 3개로, 각 분얼의 이삭이 동시에 성숙하여 일시에 수확할 수 있다는 장점이 있으며 지역적응시험 평균 수량은 3.10 MT/ha로 다수성이다. 폴리페놀, 플라보노이드 등 다양한 기능성 성분을 많이 함유하고 있으며 항산화활성(ABTS)이 42.0 mgTE/g으로 "황금찰"에 비해 30%가 높다. 현곡 천립중은 26.8 g, 주당 이삭중은 33.6 g으로 무거우며, 도복은 "황금찰"보다 강한 편이다. "동안메"는 메수수이므로 점질성이 높은 찰수수보다 빵, 과자, 국수 등 가공식품 원료곡으로 이용하기에 적합하여, 종래의 단순 혼반용을 넘어 다양하고 폭넓게 활용 가능한 품종이다(Fig. 2).
