Abstract
This study is presented to investigate the physico-chemical properties and qualities for the starch isogenic lines bred in barley(Hordeum vulgare L.).The pearling yield showed higher value in Franubet and Wafranubet than others, but the whiteness of pearled barley varied with the cultivars. The milling rate showed excellence in Franubet, fractured granular lines, whereas that of the waxy and round endosperm isogenic lines is poor. Franubet, the lines having fractures starch granule, was highest in starch content. The highest value in swelling power and water-binding capacity of the barley was proved by the lines having waxy and fractured starch endosperms. The amylogram patterns indicated that the waxy lines such as Wanubet and Wafranubet have lower initial gelatinization temperature and higher maximum viscosity than those of the normal lines.
찰성, 부정형, plump endosperm 등의 유전자를 결합시킨 보리 isogenic lines의 이화학적 품질특성과 취반특성에 대한 제 특성을 조사하였다. 종실의 천립중은 입도가 2.5 mm 이상의 것이 가장 많은 Betzes가 가장 높았으며, 정맥율은 Franubet과 Wafranubet이 높았고, 보리쌀의 백도는 품종에 따라 큰 차이를 보였다. 배유가 부정형 전분 유전자로 구성된 Franubet이 전분함량이 가장 높았으며, 제분율도 높았다. 보리전분의 팽윤력과 물결합능력은 찰성 및 부정형 유전자를 갖는 품종이 높았다. Amylogram 특성에서 찰성의 보리는 메성에 비하여 호화 온도는 낮았고 최고점도는 높았다.
