맥주보리 품질관련 형질의 재배지역간 등급별 변이정도를 조사코자 전남 남부 6개군에서 등급별로 원맥 150여점의 시료를 표본하여 분석하였다. 1. 맥주보리의 1등품은 전체 수매량의 25.9%, 2등품 62.7%, 등외품은 11.4%였고, 년차간 변이계수는 1등품과 등외품이 각각 25.0%와 43.4%였다. 2. 원맥의 물리적 특성의 지역간 변이는 천립중 9.1%, 정립율 13.2%, 곡피의 색택 35.7%였고, 발아세 및 발아율은 6.2%와 5.0%였다. 화학적 특성의 지역간 변이는 전분 4.8%, β-glucan 9.6%, 조단백질 14.0%, 곡피비율 14.7%였다. 3. 농산물검사규격에 적합한 시료는 1등품 75%, 2등품 90%, 등외는 83%였다. 4. 원맥의 등급은 색택, 조단백질, 조섬유, 곡피비율, β-glucan과 정상을, 정립율, 천립중, 발아세, 발아율, 전분량과는 부상관을 가졌다. 곡피색택은 정립율, 발아세 및 발아율과 부 상관이 있었다.
In order for investigating the variability of the characters related to malting barley quality of the different seed lots, about 150 seed lots sampled from the six districts in the southern parts of Cheonnam were analysed. The percentages of the first, second, and off grade of different seed lots of inspected malting barley were 25.9%, 62.7% and 11.4%, respectively. The coefficients of variation (CV) for years in the first grade was 25.0% and the off grade 43.4%. The CVs for 1,000 grain weight, assortment rate, grain colour, germination energy and capacity of different seed lots were 9.1%, 13.2%, 35.7%, 6.2% and 5.0%, respectively. Also, the CV for starch content of different seed lots was 4.8% and 9.6% for β -glucan, 14.0% for crude protein, 14.7% for husk rate, respectively. Seventy five percentage of seed lots in the first grade was fitted for the Agricultural Inspection Law of malting barley and the fitted rates in the second and off grade were 90% and 83%, respectively. The grade of malting barley were positively correlated with grain colour, crude protein, crude fiber, husk rate and β -glucan, but negatively with assortment rate, 1,000 grain weight, germination energy and capacity and starch content.
