뿌리가 작고 근육이 단단하며 채종이 잘 되는 무 계통 ‘원교10045호’ 육성 (The Development of a Small and Hard Root-Bearing Inbred Line, ‘Wonkyo10045ho,’ with Weak Self-Incompatibility (Raphanus sativus L.))

초록

The radish (Raphanus sativus L.) is one of the major vegetables of Korea and is consumed as the main ingredient of kimchi. To improve the texture of radish kimchi, herbs, and soup, we attempted to develop a cultivar with a hard texture. Using species native to Jeju Island, we bred ‘Wonkyo10045ho’ which produces short, elliptically shaped roots with a hard texture. Generation progress was made via the self-fertilization method using bud pollination. We selected individuals with good horticultural characteristics from each of five generations grown from 2006 to 2010. Finally, in 2015, the line was named ‘Wonkyo10045ho’, and the granting of plant variety rights (Grant number 6527) was certified in 2017 following an application for the protection of new plant varieties (application number 2015-398). The root characteristics of ‘Wonkyo10045ho,’ include an oval shape, mixed white and green root skin, and a white inner root color. ‘Wonkyo10045ho’ had a sugar content of 4.9 Brix, with excellent sweetness, good taste, and strong pithiness. The average number of seeds per plant obtained via pollination by bees in a small net house was 609.1, suggesting that the strength of its self-incompatibility was not strong and male sterility might be advantageous. Therefore, it is expected that this variety will be useful as a material for improving the competitiveness of domestic farmers and for stable radish exports.
