초록
세계는 지금 치열한 자원전쟁에 휩싸여 있다. 원유의 가격급등과 품귀현상에 따라 선진국들도 대체 에너지 개발에 열을 올리고 있다. 신재생에너지의 효율성, 경제 성을 제고하기 이전까지는 당분간 바이오연료를 활용하 는 것이 대안이다. 바이오연료로 활용하기 위해서는 몇 가지 고려해야할 것이 있다. 즉 식량생산과의 경합을 최 소화해야 하며 에너지 고정효율이 높은 작물을 이용해 야 한다. 그리고 그 부산물을 활용할 수 있어야 할 것이 다. 고구마는 이러한 조건을 모두 충족하고 있는 우수한 작물로 재평가되고 있다. 따라서 고구마의 유전자원을 수집, 평가하여 목적에 맞는 계통을 선발하고 전통적 육 종 및 형질전환 기법을 활용하여 목적에 맞는 효율성 높 은 품종을 개발하여야 할 것이다.
Abstract
In many countries including China and U.S., researchers are developing methods to use sweetpotato as raw material for biofuel. We consider the sweetpotato is not only a source of green fuel, it eventually will provide various material including paper, adhesives, biodegradable plastics, and secondary metabolites. Sweetpotato is one of the high efficiency crop because it yields more calories per unit area than either maize or potato, and it requires the shortest growing cycle of the root crops grown in the tropics. Sweetpotato is the most useful crop for the coming starchbased industry era. Sweetpotato genetic resources are collected, characterized, evaluated, and maintained by U.S., China, Japan, and the International Potato Center. New varieties of sweetpotato using the proper genetic resources and molecular breeding will be developed to cope with the global food and energy in 21st century.
