본 품종들은 우리나라 남부지방에 적응한 양질유, 양질막 다수성 품종을 육성하기 위하여 Erra(female)와 Tower(male)를 인공교배하여 육성한 양질유, 양질박, 다수성 품종으로서 목포51호, 목포52호라는 계통명을 부여하여 지방 적응 연락 시험 및 농가 실증 시험을 거쳐서 장려 품종(내한유채, 영산유채)으로 결정된 품종이다. 특히 본 품종들은 한 조합 내에서 장수, 다분지, 다협, 다립 품종으로 수량 형질이 우수하며, 유질에서 지방산 조성이 극히 양호하며 불량 지방산은 전혀 함유치 않고 양질 지방산인 oleic acid과 linoleic acid이 80% 이상 함유된 양질유 품종이며, 박에서도 glucosinolate가 전혀 없는 무독박 품종이다. 또한 생산력은 전국평균 16~22% 증수된 다수성 성분 육종 품종들이다.
Naehanyuchae and Youngsanyuchae were originated from the cross between "Erra(female)" and "Tower(male)". The cultivars were made at Bioenergy Crop Research Center, National Institute of crop science, Rural Development Administration, Korea in order to develop the high cold tolerant and yielding rapeseed variety with non-erucic acid and non-glucosinolate as good seed quality indicator. The superiorities of these varieties have been shown through the regional performance trials and demonstration farmers fields. Naehanyuchae and Youngsanyuchae had good agronomic characteristics related to yield potential such as many valuable branches and pods, and long pod length. The seeds of these new varieties composed of the 80% of oleic acid and linoleic acid without erucic acid, and glucosinolate was not extracted in the oil cake. The average grain yields increased by the from 16% to 22% according to the regional performance trials compared to check variety.
