This study was conducted to investigate the effect of highland (Daekwallyung, altitude of 800m above sea level) production of cucumber (Cucumis sativus L.) seedlings for retarding culture in lowland (Kangnung, altitude of 20m above sea level). Cucumbers (cv. Jangilbanbaek, Jeongsunyeoreum and Ginseollok) were raised during 25 days from 31st July to 25th August, and then planted under the rain-shelter at Kangnung 25th August. Mean and minimum temperature during raising seedlings at Daekwallyung, $20.9^{\circ}C$ and $16.1^{\circ}C$ were $3.7^{\circ}C$ and $5.3^{\circ}C$ lower than those of Kangnung, respectively. T/R ratio of the seedlings produced at Daekwallyung was lower than that of Kangnung, but chlorophyll contents were higher. Daekwallyung seedlings were higher female/male ratio compared with seedlings from Kangnung. Marketable yield from cucumber seedlings (cv. Jeongsunyeoreum) produced at Daekwallyung was 32% higher than that of Kangnung. These results showed that cucumber seedling raising place was Daekwallyung for the retarding culture during summer season, particularly, and the best cultivars was Baekchim (cv. Jeongsunyeoreum).
