Abstract

This study was aimed to investigate the difference for carbohydrate accumulation in both the red skinned tuber and white skinned tuber of Jerusalem artichoke (Helianthus tuberosus L.), and to evaluate their tuber yield of seven lines collected from Korea. Jerusalem artichoke tubers were divided into two groups regarding to their skinned colors. Red skinned tuber collected from Euisung region showed the lowest tuber yield as 3,100 kg per 10a, otherwise white skinned tuber collected from Imdong region resulted in the highest tuber production as 6,300 kg per 10a among the six kinds of white skinned tubers. Yield of white skinned tuber was higher than that of red skinned tuber. It was inferred from the result that carbohydrate accumulation in white skinned tuber was highly increased compared to red skinned tuber since after early tuber enlargement.
