영문 초록

The objectives of this study were to investigate variations of erucic acid content due to isolated distance of zero erucic acid varieties from high erucic acid variety and to determine the rates open-pollinated and crossed between zero and high erucic acid varieties when planted on the same area in producing rapeseed. Fourteen varieties with zero erucic acid and one high erucic acid variety were used in the experiment. Selfing was the most effective for maintaining zero erucic acid varieties. When planted 10m, 100m, 500m and 1,000m apart from high erucic acid variety, seed of zero erucic acid varieties had 4.8%, 3.9%, 3.1% and 0.4% in average of erucic acid content, respectively. The range of the 14 varieties was from 1.6% to 10.2% according to the varieties. Thus recommendable distance isolated from high erucic acid variety was 1km for economic seed production of rape seed varieties with zero erucic acid variety. However, Youngsanyuchae, which is zero erucic acid variety, had 24.2% erucic acid when planted in isolated island of Jeju due to crossing with volunteers which were high erucic acid varieties cultivated before. It is recommended that zero erucic acid varieties should be planted over 1km isolated field just after completely removing the volunteenrs plants of high erucic acid for pure seed production of zero erucic acid varieties.
