In order to select sweetpotato varieties with excellent tip characteristics, we investigated the appearance, yield, and functionalcompounds in 32 domestic sweetpotato varieties. During the cultivation period, the total production of sweetpotato tips among the differentvariety ranged from 1,780 to 9,923 g/m2, with that of the Gogeonmi variety being the highest. The lutein content among varieties rangedfrom 21.7 to 47.0 mg/100 g and was highest in the Juhwangmi variety, whereas the ß-carotene content ranged from 25.5 to 183.4 mg/100g and was highest in the Hayanmi variety. The total polyphenol content ranged from 30.7 to 74.4 mg CAE/g, and it was high in the Pungwonmi,Daeyumi, and Dahomi varieties at 74.4, 73.8, and 72.9 mg CAE/g, respectively, whereas the DPPH radical scavenging activity of tips rangedfrom 88.6% to 91.6%, with Gogeonmi and Healthymi showing the highest value of 91.6%. ABTS radical scavenging activity was found tobe lowest in the Yeonjami variety at 86%, whereas the remaining 31 varieties showed values in excess of 96%. ABTS radical scavengingactivity showed a high positive correlation with total polyphenol content. On the basis of these analyses, we identified Juhwangmi with highlutein content, Hayanmi with high beta-carotene content and high yield, and Gogeonmi with high DPPH radical scavenging activity and highyield, as being suitable varieties for tip cultivation. We anticipate that these sweetpotato varieties with excellent tip characteristics will beused as parents for the breeding of varieties for vegetable use.

The lutein content among varieties rangedfrom 21.7 to 47.0 mg/100 g and was highest in the Juhwangmi variety, whereas the ß-carotene content ranged from 25.5 to 183.4 mg/100g and was highest in the Hayanmi variety. The total polyphenol content ranged from 30.7 to 74.4 mg CAE/g, and it was high in the Pungwonmi,Daeyumi, and Dahomi varieties at 74.4, 73.8, and 72.9 mg CAE/g, respectively, whereas the DPPH radical scavenging activity of tips rangedfrom 88.6% to 91.6%, with Gogeonmi and Healthymi showing the highest value of 91.6%.

We anticipate that these sweetpotato varieties with excellent tip characteristics will beused as parents for the breeding of varieties for vegetable use.
