논 적응성이 높고 다수성인 유채 1대 잡종 품종 ‘아름’ = ‘Areum’: F1 Hybrid Rapeseed with Superior Paddy Adaptation and Yield

다국어 초록 (Multilingual Abstract)

The F1 hybrid rapeseed (Brassica napus L.) exploits heterosis to deliver greater yield, stability, and uniformity than open-pollinated cultivars, making it suitable for largescale cultivation. In Korea, cultivation is shifting from landscape and apiculture to expanding edible oil production and increasing the demand for paddy field-adapted hybrids. Using Mokpo-CGMS as the female and the pollen parent ‘09003-B-126-2-1-3,’ we developed the breeding line ‘Dangyo 80,’ which, after multi-environment evaluations of yield and oil quality against ‘Sunmang,’ was selected as a new cultivar ‘Areum. ’ ‘Areum’ exhibits growth habit type IV, yellow flowers, and a red seed coat. Its flowering and maturity times are comparable to ‘Sunmang. ’ Major growth indices did not differ significantly among cultivars; however, while ‘Areum’ showed slightly greater lodging susceptibility, it displayed higher resistance to Sclerotinia stem rot. Notably, in paddy fields ‘Areum’ achieved a higher plant density per square meter than ‘Sunmang’ which produced a 31% yield increase. In fatty acid composition, ‘Areum’ had higher oleic acid content (65% vs. 60%) and lower erucic acid (0.95% vs. 1.35%) than ‘Sunmang,’ indicating improved suitability for high-quality edible rapeseed oil production (Registration No. 9755).
