본 시험은 2006년 고령지농업연구소에서 육성한 ‘하령’ 감자를 실제 농가에서 재배함으로써 다양한 병원균에 대한 포장저항성을 평가하여 친환경 재배 가능성을 검토하기 위하여 수행되었다. 품종별 평균 AUDPC는 ‘수미’ 품종이 1377.7, ‘하령’ 품종이 590.3으로서 ‘수미’ 품종보다 ‘하령’ 품종이 매우 강한 포장저항성을 나타내었으나, 시험처리 간에는 뚜렷한 경향을 나타내지 않았다.수량은 모든 처리구에서‘하령’ 품종이 많았으며,단위면적(10a)당 평균 수량은‘하령’품종이 2,870 kg, ‘수미’ 품종이 2,301 kg으로 ‘하령’ 품종이 25% 증수를 보였다. 두 품종의 평균 건물률은 ‘수미’ 품종이 16.1%, ‘하령’ 품종이 18.8%로서 ‘하령’ 품종이 2.7% 높았으나, 처리 간 건물률의 차이는 나타나지 않았다. 본 시험을 통하여 ‘하령’품종은 친환경 감자 재배를 위한 품종으로 매우 적합할 것으로 확인되었으며,시비수준,병해관리 등에 대한 추가적인 연구가 진행되어야 할 것으로 판단되었다.

The experiment was conducted to investigate the potential for environmentally friendly cultivation of cv. Haryeong, which was bred by the National Institute of Highland Agriculture in 2006, through evaluation of the late blight field resistance at the farmer's practices level. cv. Haryeong showed higher field resistance to late blight as 590.3 in mean Area Under the Disease Progress Curve (AUDPC) during the cultivation period than cv. Superior as 1377.7 in AUDPC. However there was no observed different trend among the experimental treatments. Mean of tuber yield of cvs. Haryeong and Superior were 2,870 kg/10a and 2,301 kg/10a, respectively, and in all experimental treatments Haryeong was 25% higher than those of Superior. Mean of dry matter content of Haryeong and Superior were 18.1% and 16.1%, respectively, and there were no significant differences among the experimental treatments. cv. Haryeong was confirmed as a suitable cultivar for environmentally friendly cultivation in this experiment. In the future, additional research on fertilization and disease management will be required.
