‘청풍찰’은 기계수확 적응성이 우수한 단간형 초형을 갖추고, 다수성 및 재배 안정성이 뛰어난 찰수수 품종 개발을 목적으로 육성된 품종이다. 2009년 국립농업과학원 농업유전자원센터로부터 분양받은 유전자원(K269609)을 기본집단으로 순계분리법을 통해 육성하였으며, 2015~2016년 생산력검정 및 2017~2018년 전국 7개 지역 지역적응시험을 거쳐 2021년 최종 품종보호 등록되었다(등록번호 제8656호). ‘청풍찰’의 출수일수는 68일로 중생종에 해당하며, 이삭 형태는 도란형⋅중간형으로 이삭밀도는 조밀한 편이다. 종실색은 적갈색이며 배유특성은 찰성이다. 간장은 109 cm로 기계수확에 적합한 단간형 초형을 가지며, 이삭길이는 27.1 cm, 주당 이삭 수는 1.4개, 이삭 무게는 95 g으로 ‘소담찰’보다 우수하였다. 도복지수는 1로 내도복성이 강하였으며, 깜부기병, 이삭곰팡이병 및 주요 해충에 대한 포장 피해가 관찰되지 않아 재배 안정성이 우수한 것으로 확인되었다. 조단백질, 아밀로스, 무기성분 및 항산화 활성 등 영양성분과 기능성 성분은 ‘소담찰’과 유사한 수준이었다. 생산력검정(2015~2016)에서 평균 수량은 4.42 MT/ha로 ‘소담찰’ 대비 22% 증수되었으며, 전국 7개 지역 지역적응시험(2017~2018)에서는 3.57 MT/ha로 ‘소담찰’ 대비 48% 유의하게 증가하여 국내 육성 찰수수 품종 중 최고 수준의 수량성을 나타내었다. ‘청풍찰’은 재배 안정성이 우수하고 혼반용 등 다양한 용도로 활용이 가능하며, 특히 충북 제천 및 단양 지역을 중심으로 재배면적의 약 40%를 차지할 정도로 현장 적응성과 농가 선호도가 높아 지역 수수 산업의 경쟁력 향상에 크게 기여할 것으로 판단된다.

‘Cheongpungchal,’ a waxy sorghum (Sorghum bicolor (L.) Moench) cultivar, was bred to improve the adaptability of mechanized harvesting, yield potential, and cultivation stability for labor-saving production. It was developed through pure-line selection from a genetic resource (K269609) introduced in 2009, selected in 2019, and registered in 2021. This cultivar is medium-maturing, with a heading time of 68 days. It has an elliptical dense panicle with red-brown grains and a waxy endosperm. The culm length was 109 cm, which is suitable for mechanized harvesting. The panicle length (27.1 cm), number of panicles per plant (1.4), and panicle weight (95 g) were greater than those of the standard cultivar ‘Sodamchal.’ ‘Cheongpungchal’ showed strong lodging resistance and tolerance to major diseases and insect pests, indicating stable field performance. In replicated yield trials (2015-2016), the mean grain yield was 4.42 MT/ha, 22% higher than ‘Sodamchal’. In regional yield trials at seven locations (2017-2018), the mean yield was 3.57 MT/ha, representing a 48% increase. Nutritional composition, functional components, and antioxidant activity were not significantly different from those of the standard cultivar, indicating that ‘Cheongpungchal’ maintained equivalent nutritional quality. This cultivar has been widely adopted in Jecheon and Danyang, accounting for more than 40% of the region’s cultivation area, indicating its high adaptability and farmer preference. These results demonstrate that ‘Cheongpungchal’ maintains nutritional and functional properties equivalent to previously developed waxy sorghum cultivars, while exhibiting superior yield potential and adaptability for mechanized harvesting, contributing to labor-saving sorghum production (Registration No. 8656).
