초록

고구마 바이러스 무병묘의 지역에 따른 우수성을 입증하기 위하여 바이러스 무병묘와 일반묘를 대상으로 5지역(논산, 보령, 익산, 무안, 함안)에서 5개의 품종(주황미, 신자미, 신황미, 신건미, 그리고 연황미)으로 바이러스 무병묘 실증 시험을 진행하였다. 1. 2010년에 수행한 5개 지역 5개 품종의 일반묘와 무병묘의 비교 시험 결과 품종에 따라 최대 68%(신자미, 익산) 생산량이 증가하였으며, 최소 10.7% 감소(신자미, 함양)하였다. 2. 신자미를 제외한 모든 품종은 모든 지역에서 최대 59%(주황미, 함양) 최소 7%(신자미, 무안)증가하여 무병묘가 일반묘에 비하여 경제성이 높았다. 3. 덩굴길이나 무게는 품종과 지역에 따라 무병묘가 일반묘보다 생육이 나빴으나 생산성과는 무관하였다. 4. 논산에서 생산된 무병묘의 상저괴근수는 무병묘가 일반묘보다 3품종(신자미, 연황미, 신건미)에서 낮았으나, 괴근의 평균중이 높아 총생산량은 높았다. 이는 초기 발근 시점인 20일 이내 평균 기온이 다른 지역보다 높아 발근율이 낮아져 생긴 현상으로 판단된다. 5. 모든 품종에서 품종 특성에 맞게 육색과 피색이 더욱 선명하였으며, 괴근의 모양 등 외관 평가에서 무병묘(7~9)가 일반묘(평균3)보다 우수하였으나 당도와 전분가에는 영향이 없었다.

To analysis of virus free sweetpotato effect, 5 virus free sweetpotato and virus normal sweetpotato varieties were planted in 5 different regions at 2010 year. The average yields of virus free sweetpotato are showed different results according to regions. Sinjami which cultivated at Iksan were increased maximum 68% compare to normal. However, Sinjami which cultivated in Hamyang were decreased yield 11% compare to normal. Analysis of tuber formation ratio of Sinjami, Yenhwangmi, Singeonmi which cultivated in Nonsan were decreased tuber number compare to normal. However, 3 varieties were all increased on Average storage root weight and yield of marketable storage root. In the results of analysis of marketable storage root according to cultivated regions and varieties, all varieties except Sinjami which cultivated in Hamyang were increased yield. Also, quality of virus free sweetpotato were enhanced 7 to 9 compare to virus infected sweet potato which showing average 3. Contents of starch between virus free and virus infected sweetpotato were not affected by virus. Virus free sweetpotato were more increased starch products according to increased total production yield. Also, $Brix^{\circ}$(%) was not showing difference between virus free and virus infected sweetpotatoes. In this experiment, Virus free sweetpotato are enhanced production yields and quality. Therefore, we suggested that virus free sweetpotato is one of the methods to reduce damage by sweetpotato virus.
