영문 초록

The present study was performed to select suitable potato (Solanum tuberosum L.) varieties for double cropping in seed production using aeroponic system, the nutrient solution was sprayed for 20 seconds in every 3 minutes, and potatoes were planted into styrofoam at a distance of 25 cm between plants. Transplantation was completed in September 9 and potatoes were harvested in November 12. The 10 trial cultivars, Atlantic , Dejima , Haryong , Hongyoung , Jayoung , Jopung , Jowon , Namsuh , Seohong , Superior were examined for growth and yield. The shoot growth of all cultivars at the early stage was better than ``Superior``, however, no difference was observed at the late stage of plant growth. In addition, Superior showed a excellent root growth during the early plant growth stage, however, increased root growth was only found in Jayoung , Seohong , during the late plant growth stage. The stolon weight was greater in the order of Seohong > Superior > Jayoung > Hongyoung . Particularly, the number of tuber in Jowon was 22.4/plant that was over twice than Superior (11.3/plant). As results of the current study, therefore, we concluded that four cultivars Seohong , Jayoung , Hongyoung , Jowon were the most suitable cultivars for basic seed production using aeroponic system in Autumn potato.
