Abstract
The overall objective of this study was to determine which variety of carrot-10 Japan varieties or 6 domestic varieties- produces the optimum quality, when cultivated on Jeju Island. Plant height, leaf number and leaf weight were observed to be more superior in the purebred variety ‘Jungang’than other varieties. further studies, however, skewed the crossing variety ‘Bureoun’was superior to all others. Furthermore, when comparing root diameter, root length and root weight, the ‘Bibary’was superior in both the purebred and crossing variety, When researching Japan varieties, the crossing variety, ‘Jung’showed an increase in underground root. The purebred variety ‘Donghae’also showed an increase in underground root. Marketable yields in domestic varieties were greatest in ‘Hapa’, while in Japan varieties, ‘Kaneko’was the most productive. The percentage of root cracked was 15％ greater in ‘Bureon’. In the purebred variety, Jungang, the percentage was only 10％. The percentage of roots branched was highest in ‘Hidomi’which showed a rate of 9%, The roots branched rate was 2% for ‘Jung’and 6％ for‘Donghae’. Considering the percentage of roots clacked or branched, the marketability of carrots was higher in Japan varieties in comparison with domestic varieties. Therefore we conclude that, in the cropping patterns of carrots, the domestic variety has an advantage over the Japan variety.
