초록

This work was conducted to identify sweet potato [(Ipomoea batatas (L.) Lam.)] cultivars showing high yield and processing suitability in the Jeonbuk region of Korea. Shoot-slips (30 cm in length) of 14 cultivars were planted with a planting density of 75×25 cm on May 30, and cultivated with black film mulching. Vine elongation at 30 days after planting was significantly increased (> 90 cm) in ‘Dahomi’ and ‘Sinhwangmi’, and was excellent (> 250 cm) 120 days after planting in ‘Sinhwangmi’, ‘Shinyulmi’, ‘Daeyumi’, ‘Jinhongmi’, and ‘Yeonhwangmi’. The branch number per plant showed a dramatic increase in ‘Shinzami’ 30 and 120 days after planting. The leaf number per plant showed the highest increase in ‘Shinzami’ 30 days and in ‘Sinhwangmi’ 120 days after planting. Total weight, mean weight, and number of marketable tubers per plant were significantly higher 150 days after planting than that 120 days after planting. Marketable tuber yield at 120 days was high, over 2.5 ton/10a in ‘Daeyumi’, ‘Dahomi’, and ‘Jeonmi’, and was considerably increased, from 3.2 ton/10a to 3.5 ton/10a, 150 days after planting. Total weight of marketable tubers per plant and marketable tuber yield 120 and 150 days after planting had significant positive correlations with vine length and number of nodes 30 days after planting. Starch value was significantly higher 150 days after planting than that 120 days after planting. ‘Daeyumi’ and ‘Jeonmi’ had good growth vigor, high yield, and high starch content; ‘Dahomi’ also exhibited beneficial traits such as good growth vigor, high yield, and bright orange-colored flesh.
